[Solved] Windows Resource Protection could not perform the requested operation
When some Windows functions don’t work or Windows crashes, use System File Checker (SFC) to scan and restore corrupted Windows system files. However, as many users reported, when they perform a “sfc /scannow” command, “Windows Resource Protection could not perform the requested operation” error pops up.
If you’re annoyed by this problem, don’t worry. You can fix it with our help here:
Solution 1. Run SFC in safe mode
1) Press the Windows logo key and R key at the same time to invoke the Run box.
2) Type msconfig and press Enter.
2) Tick on Safe boot in Boot and click OK.
3) Click Restart when asked by System Configuration.
Your Windows will then boot into safe mode
4) Run sfc /scannow to see if it works.
Solution 2. Run CHKDSK
If there were errors on your hard drive, SFC would also fail. CHKDSK can check the integrity of your hard disk and fix various file system errors:
1) Type cmd in the search box from Start. Then right-click on Command Prompt to choose Run as administrator.
2) Click Yes when prompted by User Account Control.
3) Type chkdsk /r in the open Command Prompt window and press Enter. Enter y, When asked to schedule checking disk.
4) Close the Command Prompt window, and restart your PC.
Then it will start checking disk and fix the errors detected automatically.
5) Run sfc /scannow to see if it works.
