Windows 10: corrupted files!

Hi! So I was playing Warzone and left my pc to go have dinner. Come back and I see the WiFi isn't working. Then also can't windows-tab out. After a bit I realise that any windows default things aren't working, eg. start button, anyhting on taskbar and trying to opening apps such as settings through task manager run task or opening a photo with photos gives me the error: "class not registered." I can open some 3rd party apps, but not all. Also the WiFi just stopped working despite my WiFi chip still working. Online I was told to use powershell to fix the issue, but when I open powershell, it instantly closes. I tried resetting the whole PC and it said trouble resetting PC. I tried reinstalling windows and it said error with second-boot and all changes were to be undone. I opened CMD prompt through windows safe mode launch and I tried a SFC scan and got an error message. What should I do??

Corrupted file RAR

If the archive has been created using WinRAR, why don't you try WinRAR itself? It has a built-in repair feature for repairing corrupted archive (ZIP as well as RAR). Follow the steps given below:

• Open WinRAR application in your system.
• Now click on File tab > Open or simply press Ctrl+O.
• A small window "Find Archive" will pop up. Locate the corrupt RAR archive from your system directory and select it.
• Now click Open button.
• Click Tools tab > Repair archive or simply press Alt+R.
• Again a small window "Repairing File name.rar" will pop up.
• Now click Browse to select a location to save the repaired archive.
• Check the box "Treat the corrupt archive as RAR" and click OK.
• WinRAR will start repairing of corrupt RAR archive. Once it gets completed click Close.

I hope the above steps will help you repair the corrupted RAR archive.

Thanks.

Hi Vincent,

Thank you for posting your concern here in Microsoft Community.

Please perform the below steps and see if it helps to resolve the issue.

This issue may happen due to system file corruption. I suggest you to run System file checker. System File checker (SFC) scan is done to check if there are any corrupted system files that could be causing this issue. Kindly follow
the below given steps:

• Press Windows key + X, select
  Command prompt (Admin) to bring up elevated Command prompt.
• In Command prompt type sfc/scannow and press enter.
• Restart the computer.

If no corrupted system files were found in the previous state, then I suggest you to try the following steps:

• Open command prompt by pressing Windows key + X and selecting “Command prompt admin”.
• In command prompt, type the following commands and press Enter after each command:

DISM.exe /Online /Cleanup-image /Scanhealth

DISM.exe /Online /Cleanup-image /Restorehealth

• Close the command prompt and restart the PC and check if it works.

Hope this information helps. Please post us if you need any further assistance with Windows.

Thank you.
