Microsoft tries in every way to improve the stability of its system. One way to implement this striving is to introduce testing of manufacturers for compatibility. Now the system checks the legality of the files installed. However, because of this, you can often find an alert: "Unable to check the digital signature of the drivers (code 52)", which is found in Windows 7, 8, 10. Today we will tell you what to do when this notice appears and what's wrong with the drivers .
Purpose?
Thanks to the digital signature of the developer (CPR), the ordinary user is able to establish only verified for compatibility of iron, devices and firewood to them. CPR eliminates the set possible problems and reduces the threat of installing undesirable software (including viruses), but also limits, because to attach equipment without electronic certificate will not work.
The phenomenon is accompanied by a message about the absence of such a signature (code 52) and the alert that last change An incorrectly signed file was installed, or a malicious program of unknown origin. Even if you choose item "Equally install"At the end, the equipment will still work unstable.
To solve the problem, you will need to disable the checkup option in Windows. That's when you have to disable the monitoring of the check:
- The use of obsolete device, with which the firewood is coming, not passing a test for compatibility with the OS.
- When installing custom drivers.
- To establish the functioning of non-standard devices, but their number is small.
How to fix the code 52 in Windows (7, 8, 10)
If you are confident in the software supplier and take all the risks for yourself, then deactivate the tracking system. Disable monitoring can be dangerous, because in the process, the user can establish a malicious software, not knowing about it. Therefore, it is recommended to cancel the test only at the time of operation / testing certain functions and equipment. Methods of manual shutdown:
- change local group Policy;
- modification of the operating boot;
- self signature of firewood (for experienced users).

When you turn on checking this equipment It will be impossible again.
For disposable testing
Do not want to risk stability and security? Suitable method - Mode without testing digital signatures. Here brief instructions:
This is a suitable solution in situations where the use of equipment needs only from time to time or once.
Periodic use
If it is necessary to deactivate the test for a certain time, then the two options are suitable.
Group Policy Adjustment:
Do not want to wander around the configuration? Then there is a simpler method.
Changing download parameters:
In this case, the reverse inclusion procedure looks like this.
- Turn on the console from the admin.
- Register: bCDEDITIT.EXE / SET LoadOptions Enable_integrity_Checks. Wait for execution.
- Register: bCDEDITIT.EXE / SET Testsigning Off. Wait for completion and restart the transaction.
Independent signature
As in the previous case, there are several options. An easier method is to use the appropriate software that performs the signature procedure. For example, Driver Signature Enforcement Overrider. How to make a signature with it, see here:
Conclusion
There are more complex but effective methods To correct the error, "the driver's digital signature cannot be verified (code 52)". Independent signature programs Microsoft Windows. SDK for windows and Windows Driver. Kit. Allows you to use the equipment more comfortable, so if you are settling the work of the equipment, which will also use others, then this option is preferable. To perform the necessary manipulations will also need .Net Framework. 4 .
Please note that the independent signature does not lead to the disconnection of the protective mechanisms of the OS, which makes it possible to use the equipment longer.
Sometimes when trying to run or restart Windows XP, the above error may appear. This is due to the lack of or damage to the necessary files. windows registry. There may sometimes be missing other directories, for example: / Windows / System32 / Config / Software, / Windows / System32 / Config / System or / Systemroot / System32 / Config / Software. In this case, errors may look like this:
- "Unable to run Windows XP due to a spoiled or missing file / Windows / System32 / Config / Software"
- "STOP: C0000218 (Failure in the registry file) The registry fails to load the partitions family (file) / Systemroot / System32 / Config / Software or its log or a spare copy"
How to restore Windows XP boot.
A file error may also occur Lsass.exe.. The causes of these errors may be as follows:
- Incorrect or unforeseen completion windows work.
- Problems with hard disk Computer or laptop, perhaps he came out or almost failed.
- You yourself, accidentally or deliberately removed the system files necessary for Windows XP.
How to remove this error and run Windows XP, solving the problem?
In addition to reinstalling the operating system, there are several ways to solve this problem. The meaning of these methods is reduced to restoring damaged or deleted files and registry catalogs.
First option.
You must start the computer from the boot CD / DVD disk or flash drive. For this, such products are suitable such as Live CD from Dr.Web, it is built in the convenient file manager and the program for checking the PC to viruses and trojans. In order to download a computer or a laptop from a disk or flash drive, you need to press when downloading F1, F2 or DEL, and set the priority of booting from the disk.
Loading, run the file manager, select the / windows / System32 / Config / System directory on the left / Windows / Repair / System on the left / system32 / refig / system. All that is copied to the left window to the left. After that, reboot your computer or laptop, without forgetting to set back the download from the hard disk. If the actions described above did not help, and the system as before it does not start, then you should not despair, because there is a second way to solve the problem.
Second option.
if you have installation disk With Windows XP, you can restore missing files using the recovery console. To do this, set the boot from the disk in the BIOS. When you start from the disk, press the + R key to start the console windows restoration. After starting, we sequentially enter the command, after entering each click + Enter:
MD TMP Copy C: / Windows / System32 / Config / System C: /Windows/Tmp/System.Bak Copy C: / Windows / System32 / Config / Software C: /Windows/Tmp/Software.Bak Copy C: / Windows / System32 / Config / Sam c: /windows/tmp/sam.bak Copy C: / Windows / System32 / Config / Security C: /Windows/Tmp/Security.bak Copy C: / Windows / System32 / Config / Default C: / Windows / TMP / DEFAULT.Bak
delete C: / Windows / System32 / Config / System Delete C: / Windows / System32 / Config / Software Delete C: / Windows / System32 / Config / SAM DELETE C: / Windows / System32 / Config / Security DELETE C: / Windows / System32 / Config / Default
copy C: / Windows / Repair / System C: / Windows / System32 / Config / System Copy C: / Windows / Repair / Software C: / Windows / System32 / Config / Software Copy C: / Windows / REPAIR / SAM C: / Windows / System32 / Config / Sam Copy C: / Windows / Repair / Security C: / Windows / System32 / Config / Security Copy C: / Windows / Repair / Default C: / Windows / System32 / Config / Default
You can use the standard features of the system: try to boot with the "last successful configuration". This is done when the computer starts. Also, if you have previously activated automatic recovery Systems, you can make it rollback.
If you decide the problem, but the mistake is repeated again and again, most likely with your hard drive, serious problems and live him not long, so think about his replacement and backup copying Important data.
According to the latest statistics, the percentage of computational systems running software package Microsoft - Windows is about 91%. In the light of this, it is not to be surprised at the abundance of questions from users who are somehow related to the work of this particular operating system. One of the most commonly occurring is associated with the features of the work of the concomitant software.
So, sometimes an attempt to install the application leads to an error "Windows cannot be installed to install the necessary files 0x80070017". Such malfunctions can be associated both directly with the Windows operating system itself and with third-party applications.
"Problem" carrier
Although many owners computing machines Already practically abandoned the use of CDs, preference to media based on solid-state flash memory, yet the first are still found. One of their disadvantages is the impossibility of unmistakable reading recorded data with inaccular storage and scratches on the mirror surface. Thus, if the system window appears when working with CDs when you try to install the application, the Windows window appears, which reports that Windows cannot install the necessary files, then you need to make sure that there are no damages on the carrier. Sometimes to restore performance, it is enough to wipe the disk, eliminating the contamination, fingerprints, etc.
Incorrect entry
In addition, the recording program must be properly configured, so the different functions of the "renovation" must be disabled. And finally, it should be remembered that those rewritable are inferior in quality to their simpler rates of standard R (both + and - and -). The best option "treatment" is the use of a flash drive. You can also try to switch the hard drive mode with AHCI on IDE in the system BIOS.
Blocking protection
Both of the above points concern primarily errors arising when installing the operating system itself on a computer. No less often, users receive a message that Windows failed to install the necessary files when working with applications. To deal with the cause of what is happening, summarize the process of installing programs. When you click on the executable file, the background extracts in it in it in an intermediate folder, from which, from which from bricks, is created in the target directory of the holistic set of program files. If an anti-virus protection is installed on the computer that found in one of the unpacked files a danger, then access to it is blocked. And since often the user does not even report about it, then the result is issued system error "Windows failed to install the necessary files." Thus, when you appear this, you can try to disable antivirus protection during the installation of the application.
If re-installation passes without errors, then the reason in the antivirus or, indeed, in the presence of threats in one of the files. Obviously, such a check is potentially dangerous due to the risk of infection of the system, so it is recommended to try to install the same application obtained from another source.
Internal damage
If the user is reported that Windows failed to install the necessary files, then one of the reasons may be incorrect work Installator. Earlier, we described the application installation process. It occurs "under the control" of the executable module, which indicates the system which files to be transferred from the time folder, disparaging compressed data. Consequently, any failure in its operation just leads to the message "Windows failed to install the necessary files." Although, repeat, this is, just one of possible options. The decision is to test the performance with a similar application from another source.
Storage device
Since the installation is carried out on some disk (Winchester, flash drive, etc.), then when the free space is exhausted on it, the installation cannot be completed without errors. In addition, failures when copying files can be caused by file system errors on the medium itself. In these cases, you need to make sure that the free space is enough, as well as check the disk for errors.
In some cases, when the user tries to format its flash drives, the system gives an error "Windows cannot complete formatting".
Sometimes it happens when working with HDD, DVD RW and other drives, but most often such a problem is subject to Micro SD.
Why does Windows writes such text?
This happens because OS for some reason cannot independently format or the cause of the SD card or hard disk malfunction.
It is also possible that before the memory card was used to another operating system (Linux, Mac OS and the like) and the file system is incomprehensible to Windows.
It is the impossibility of working with file system It is the most common cause of such an error.
This error looks like shown in the picture.
But what to do when the system gives out such a mistake? There are several ways.
The easiest of them is performed standard means Windows and available both for Windows 7 and for Windows 10 and even for old good Windows XP.
Solving the problem with the system of the system
Step-by-step instructions, how to remove this error When formatting a removable disk, it looks like this:
- Press the combination of the Win + R buttons on the keyboard. Thus, we open the "Run" dialog box. The image shows which keys to click on the keyboard and the window, which should appear after that (circled with a green frame).
- To this window, you need to enter the following: diskmgmt.msc and press ENTER on the keyboard. Thus, we opened the "Disk Management" program.
- In the window that appears, you need to find a memory card designation. You can find out the removable media by the corresponding lettering "Removable Device" at the bottom of the program and on the image of a memory card, which differs from other media at the top.
- In one of the places marked with green frames in the photo above, you need to click the right mouse button. As a result, you can see the drop-down menu shown in the figure.
- In this menu you need to click on the inscription "Format ...". Then the flash drive will be formatted by a somewhat different algorithm than in other cases.
Clarification! Perhaps the problem is that the carrier is simply not distributed. Then the inscription "Delete Tom" (highlighted with a yellow frame in Figure No. 4) will be active, not dull, that is, it will be possible to click on it. Try to do it. After that you will need to create new volume.
Creating a new volume
To create a new volume on unallocated carrier you need to press right-click Mouse on it and in the drop-down menu select "Create a simple volume ...".
After that, the "Wizard of the Promotion of Simple Tomov" will open, in which you should not change any parameters - all leave the standard and simply press the "Next" button several times.
After that, in the "Disk Management" program opposite the flash drive, "Fixed" will be written as shown in Figure No. 6.
After that, you can again try to format a flash drive with standard means - through "My Computer" using clicking on the required media with the right mouse button and select the "Format ..." item.
Disconnect the foreign process in the system
It is possible that the formatting of the flash drive is hampered by any foreign process in the system.
To exclude this option, you need to do the following:
- Restart the computer in safe mode. To do this, open the "Start" menu, then click on the button circled in the image in green, and select "Restart" (this is for Windows 7).
The computer will turn off, and immediately turns on again. So, immediately after turning off, press the F8 button and wait for the download.
- After that, run command line On behalf of the administrator. To perform this action there are many different ways.
The easiest of them is to press the SHIFT key on the keyboard and the right mouse button to click on any free desktop place. In the menu that appears, you need to select the "Open command window" item.
- In the window that appears, you need to write the following: Format [Drive Letter]:. To find out the drive letter, you need to go to my computer and see what is written near the media, as shown in the figure (designated by arrows).
In our case, this is the letter "e", so in the command menu we write "Format E:", as shown in the photo below (circled with a blue frame) and press the Enter key.
If it does not help, you will have to use help from the side, that is third-party programs Recovery.
Disk Recovery Programs
One of these programs is D-Soft Flash Doctor. Download it on the Internet is very easy. The program window looks like shown in the figure.
In this window, you must select our media. You can find it in the letter (in our case it is "e").
To do this, just click on symbol Flash drives at the top of the program (the photo above is highlighted with orange color).
After that, you can select the item "Restore Media" (marked with a red frame). There will be a recovery, after which you can try to format the disk again.
You can also select the "Scan to Error" item.
Then the scanning will begin, and the user will be able to know that not so with his carrier.
If the flash drive is not only not formatted, and also shows that the volume is 0 MB, well helps Ezrecover. By the way, you can also find out the volume of the flash drive in "My Computer".
In the figure, the red lines are emphasized by the place where the drive is shown.
In our case, 5.18 GB is displayed there, but if you show 0 MB, boldly download Ezrecover.
Ezrecover independently finds removable media, it does not even have to indicate anything.
After opening the program, the user remains only to press the "Recover" button and wait a bit.
On the Internet there are still a lot of programs to restore flash drives, you can also try others. If nothing of all these options gives the result, the USB flash drive remains only to throw away.
On the video below, it is clearly shown how to achieve a disk formatting standard windows tools.
Not formatted flash drive, repair by means of Windows
SOLUTION OF THE PROBLEM - Windows fails to complete formatting
Error "Windows cannot be connected to the service notification service of system events" is caused by the service failure and system components Systems. The cause of the failure can be viral activity, equipment conflict, software incompatibility.
After the error appears, many system services cease correctly. Disconnect the ability to log into the system under the accounts of other users. This is one of those cases when the user sitting in the system under the administrator account will be easier to correct the problem. Despite the prevention of the system that the error "prevents the input to the system of ordinary users", sometimes Windows does not allow to change the usual account to the administrator account.
The frequent cause of the appearance of an error is damage system files As a result of viral activity. Some methods of fixing problems require windows rollback To the recovery point and other actions that can damage or delete files on the computer. Before starting an independent solution, you should save all important documents and files, create a recovery point (the instruction is attached).
Ways to solve the problem:
Using the cmd.exe command line
The error "cannot be connected to the service" can be fixed with console teams Netsh Winsock Reset and Route -f. These teams are discarded network Installations Windows for default settings, which allows you to get rid of the error and restore the performance of the system and network. Reset settings will not eliminate the cause of the problem: viruses, equipment conflict or software.
After eliminating the error, you will need to spend time on finding and eliminating the cause of the error. Alternative option - roll back the system to one of the recovery points, when there has not yet been a viral infection or other malfunction.
The following actions must be performed on behalf of (in account) Administrator:
- Press Start -\u003e Standard -\u003e Command Line or Start -\u003e Run -\u003e Enter into the cmd.exe window and press ENTER.
- Enter the Route -F command and press ENTER. The command will be executed only if the administrator's rights is available and clears the routing table from all unnecessary records. All important network and nodal routes remain workers.
- Enter the Netsh WinSock Reset command and press ENTER. The command reset one of the key system handlers - Windows Sockets.
- Reload the computer to change the changes to take effect. It is advisable to add this page to the bookmarks if Windows is notified to connect to the service will disturb once again.
Windows Sockets handler is modular and multitasking, viruses and other applications can be built into its operations. This mechanism is required to the system so that applications can enter the Internet simply, avoiding unnecessary interaction with drivers. In Windows Sockets, the most different handlers can be built, it uses antiviruses to intercept and scanning traffic for threats. If an error occurred at some stage of processing packages, the user will receive non-working Internet, malfunctions in applications and the error of the following content:
Could not connect to windows service
Windows cannot connect to the Service Notification Service for System Events. This problem prevents the login to the system with limited rights.
The user with administrator rights can view the log of system events to determine the causes of the problems.
Restoring the system from the control point
If, after using console commands and reboot the computer, the error continues to appear, and the reason for the problem was not possible to find, you can roll back the system to one of the last recovery points. To use recovery points, you need them before - this feature is disabled on many computers with Windows XP and 7.
Windows will offer to select a checkpoint and report what data will be deleted or restored. In any case, before the start of the recovery process, it is desirable to keep the most important files on removable media. It will not hurt to check the files for the presence of viruses, especially if the service event error began to appear after the infection of the computer.
Methods for running Windows recovery from the control point:
- Method 1: Press the Start, in the search bar, enter recovery and select the system restoration from the appeared options.
- Method 2: Go to Start -\u003e Control Panel -\u003e Backup and Recovery, Press the System Settings or Computer at the bottom of the screen, then click on the Run Repair System button.
- Method 3: Press Start, enter RSTRUI in the search bar and press ENTER. Either enter the same command in the Run menu (Win + R).
- Method 4: Go to Start -\u003e Control Panel -\u003e System -\u003e System Protection and Press the System Restore button in the window that opens.
Regardless of which of the way to start the recovery system is selected, Windows will offer to select a checkpoint. It often happens that automatic archiving on the computer turns out to be disabled, and the user himself did not do backups.
In this case, in the recovery and archiving section in the control panel, approximately such a picture will be observed: 
Even if things are in this way, it is still worth trying to start the recovery process. In the "Restore System File and Parameters" window, select the option "Select another recovery point" to view all available archives.
Windows automatically saves control points after the critical system updates and in a number of other cases. When restoring the system from the control point, another recovery point with the source status of files and system will be created. In other words, the system rollback can then roll back, but the backup copies of the files are still better to have on the outer carrier.
System Scanning with SFC / Scannow
You can carry out the system diagnostics by entering the SFC / ScanNow command in the control panel. In order for Windows to replace the missing, damaged or remote files, in the drive (or on another removable carrier) should be the same windows versionAs a device. This applies not only to the version of the system itself (XP, 7, 10), but also the update package (SP). It is best to use that disc from which Windows was installed on a computer.
To start scanning the system you need:
- Run the command line. To do this, enter CMD in the search bar in the Start menu, or in the Start window -\u003e Run.
- Enter the SFC / ScanNow command and press ENTER.
- Wait for the end of the system diagnostics.
Depending on the recovered files, Windows may need to restart the computer after the expiration of the system scanning. The result will also be shown: was it possible to detect errors at all, did they manage to eliminate whether other problems arose during the inspection.
You can start checking the system without the installation disk. If there are no errors, the system will not need to restore any files. If errors will be detected but the installation windows disk No, then replace damaged files will not come from. The following content is displayed: Protection Program windows resources Detected damaged files, but cannot restore some of them. There will also be a path to which you can see the check log.
Using Windows Repair Free
Try to eliminate the connection error to the system of system events you can use free version windows programs REPAIR. Before running the program, you should create a point of recovery in case of unforeseen problems.
Sequencing:
- Open Start -\u003e Programs -\u003e Standard -\u003e Service -\u003e Restore System.
- Click "Create a Recovery Point", then "Next", enter the name of the stored point and click the "Create" button again.
- Wait for the end of creating a recovery point, download Windows Repair Free or Windows Repair (All in One) from the official site.
- Install the program to the computer, start the application.
- Open the STEP 2 tab.
- Press the DO IT button to check the disk. The computer will be automatically rebooted.
- After restarting the PC, open the program again, open the STEP 3 tab and start the next step by pressing the SFC button.
- After that, you need to go to the Start Repairs Recovery tab and start the process by pressing the Start button.
- The program will propose to create a recovery point - the "no" should be answered, since the archiving was performed in advance.
- Next, you need to mark the following two points in the left side of the window:
- Remove Policies Set by Infections
- SET Windows Services to Default Startup
- Press the START button to start the scanning process. The computer should not use at all at the time while scanning is.
If none of listed methods It did not help solve the problem, it is worth using another method - disable all extra devices from the computer. For example, an error can cause simultaneous connection to a microphone PC, headphones and a music center. If the devices are not connected simultaneously, the service notification service errors do not occur.
