If you are running Windows 10, Windows 8.1 or Windows 8, first run the inbox Deployment Image Servicing and Management (DISM) tool prior to running the System File Checker. (If you are running Windows 7 or Windows Vista, skip to Step 3.)
Important: When you run this command, DISM uses Windows Update to provide the files that are required to fix corruptions. However, if your Windows Update client is already broken, use a running Windows installation as the repair source, or use a Windows side-by-side folder from a network share or from a removable media, such as the Windows DVD, as the source of the files. To do this, run the following command instead:
Note: Replace the C:\RepairSource\Windows placeholder with the location of your repair source. For more information about using the DISM tool to repair Windows, reference Repair a Windows Image.
The sfc /scannow command will scan all protected system files, and replace corrupted files with a cached copy that is located in a compressed folder at %WinDir%\System32\dllcache.
The %WinDir% placeholder represents the Windows operating system folder. For example, C:\Windows.
Note Do not close this Command Prompt window until the verification is 100% complete. The scan results will be shown after this process is finished.
To repair the corrupted files manually, view details of the System File Checker process to find the corrupted file, and then manually replace the corrupted file with a known good copy of the file.
Swipe in from the right edge of the screen, and then tap Search. Or, if you are using a mouse, point to the lower-right corner of the screen, and then click Search. Type Command Prompt in the Search box, right-click Command Prompt, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.
To view the details that included in the CBS.Log file, you can copy the information to the Sfcdetails.txt file by using the Findstr command, and then view the details in the Sfcdetails.txt. To do this, follow these steps:
Note The Sfcdetails.txt file contains details from every time that the System File Checker tool has been run on the computer. The file includes information about files that were not repaired by the System File Checker tool. Verify the date and time entries to determine the problem files that were found the last time that you ran the System File Checker tool.
After you determine which system file was corrupted and could not be repaired through the detail information in the Sfcdetails.txt file, find where the corrupted file located, and then manually replace the corrupted file with a known good copy of the file. To do this, follow these steps:
Note You may be able to get a known good copy of the system file from another computer that is running the same version of Windows with your computer. You may perform a System File Checker process on that computer to make sure the system file that you intend to copy is a good copy.
Copy Source_File DestinationNote The Source_File placeholder represents the path and file name of the known good copy of the file on your computer, and the Destination placeholder represents the path and file name of the corrupted file. For example, type copy E:\temp\jscript.dll C:\windows\system32\jscript.dll.

Repair a Windows image using DISM. You can repair offline Windows image in a WIM or VHD file, or an online Windows image. An online Windows image will also attempt to repair itself if it becomes unserviceable. The repair source for this operation is the same source that is used for Features on Demand and is determined by Group Policy settings. For more information, see Configure a Windows Repair Source. When you use the DISM tool to repair an online or offline image, you can use the /Source argument with the /RestoreHealth argument to specify additional repair source locations to use to search for the required files.
When you use the /CheckHealth sfc argument, the DISM tool will report whether the image is healthy, repairable, or non-repairable. If the image is non-repairable, you should discard the image and start again. If the image is repairable, you can use the /RestoreHealth argument to repair the image.
If you do not specify a /Source for the repair files, the default location for Features on Demand is used. For more information, see Configure a Windows Repair Source. If you specify more than one /Source, the files are copied from the first location where they are found and the rest of the locations are ignored. You can use /LimitAccess to prevent the DISM tool from using Windows Update as a repair source or as a backup repair source for online images.
In some cases, an image can be corrupted while modifying it with DISM. Use /Cleanup-MountPoints to repair it. This command will not unmount images that are already mounted, nor will it delete images that can be recovered using the /Remount-Image command.
Hi, my prusaslicer auto-repair tool doesnt work. I have the 2.7.1 version installed. But it didnt worked with ver. 2.6.0 either. The progess bar go to 50% then it just hung there and never finish the repair.
The repair tool works just fine with my PS 2.7.1. Have you tried it with a simple object? If you have some very challenging mesh, or a very complex mesh with millions of faces the auto-repair tool can take a very long time and during that time it will look as if it permanently froze. But it isn't. I have had some auto-repairs which took a whole night to complete and while doing so looked frozen until it is done.
It can help a lot if you use the "simplify model" tool before, just reduce the mesh to whatever the "Detail level high" setting suggests and check if you lost any significant details. If you lost something you can use a milder reduction by using the reduction by percent option. If the simplified model looks fine, proceed with the auto-repair tool. It should be a lot faster then.
It happen with every broken object i try to repair. And in the window repair, the progress bar goes only 50% and freeze there. And the text inside that window say "Item repaired by windows repair algorithms"
Indeed. PS is quite good at getting printable g-code out of almost any mesh, no matter how broken the meshes are you throw at it. However, not always. Sometimes there are issues with missing layers or even entire volumes.
I have a classroom of 32+ Windows 10 Enterprise machines that boot into Repair Mode every day. This has just been over the last two weeks; previously, they booted normally without issue. Restarting the machines or going to Advance Options and choosing Continue to Windows 10 causes them to launch the OS properly. The OS loaded on these machines was from SCCM, but other classrooms not experiencing any boot issues were also loaded from SCCM on the same date, so there is not a similar connection here.
Students are ingenious at times. Being as you are the only Classroom affected, I wonder if they could have done something. Would it be worth reinstalling Windows on one machine to see what happens. Could also try fixing the boot process -efi-and-uefi-repair-cds-for-windows/
And, so that we have the information here for people that happen to find it via some google-fu, we have released a updated build of Deep Freeze (8.56) that includes some fixes that should help address the causes of a lot of this type of issue.
This morning I received the ugrade version prompt for the VPN client I mindlessly clicked yes but didn't reboot and kept working... During the day I did a reboot of the laptop and received an error prompt about MFC120.dll missing. I already tried uninstalling and repair and both options don't work.
Here is what finally worked for me. I was able to successfully repair the install using the installer of the previous version. But after uninstalling and reinstalling the new version the same error occured.
Sometimes a Windows 10 system starts misbehaving to the point where repair is needed. This often takes the form of worsening performance or stability, and can originate from damage to, loss of, or corruption of Windows system files typically found in the C:Windows folder hierarchy. When that happens, users would be well advised to break out the following routine to help them set things back to rights.
The amount of time and effort required for each step goes up incrementally. Some steps involve additional work to restore the prior state of your PC more or less back to where it was prior to taking that step. Thus, the most important bit of advice I can dispense for those who must venture beyond Step 1 is this: make a complete backup of your system to provide a source for files and information that might otherwise go missing. Ignore this advice at your own risk.
