System File Checker is a tool created to assist if Windows declines to run usually because of the system being corrupted. It normally gets the issue solved by locating and recovering corrupted or missing system files to the working state. But this tool is not working well as we have expected all the time.
An expanding amount of users are stating that they get “Windows Resource Protection could not perform the requested operation” error message while performing “sfc /scannow” command.
If you’re disturbed by this issue, don’t worry. You can fix it with our help here.
There more than few way to solve this, but we will show four solutions which are expected to solve your problem easily.
Solution 1. Run SFC in safe mode
Step 1: Press the Windows logo key ￼and R key at the same point in time to open the Run box.
Step 2: Type msconfig and press the Enter key.
Step 3: Check the box on the side of the Safe boot in Boot and click OK.
Step 4: Click the Restart option when prompted by System Configuration.
Your Windows will be now booting into safe mode. Run sfc /scannow to detect if it runs properly or not.
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. But running chkdsk can solve the problem of “Windows Resource Protection could not perform the requested operation”. In order to apply this, follow these steps:
Step 1: Press the Windows key and press “cmd”.
Step 2: Right-click on the search results and select Run as Administrator.
Step 3: Click Yes when asked for User Account Control. In a case where you are demanded to enter your administrator password, make sure you enter it correctly.
Step 4: In the Command Prompt window, Type “CHKDSK C: /R” and press the Enter key.
Step 5: When asked for schedule checking disk, type y and press the Enter key again.
Step 6: Restart your PC and wait patiently until the CHKDSK is completed to check disk and fix the detected errors.
Step 7: Run SFC again to verify whether it is running properly now or not.
Solution 3: Modify the security descriptors on the winsxs folder
If the “Windows Resource Protection could not perform the requested operation” error message is still popping up, it implies that the issue has nothing to do with the disk failures. Then continue to check another potential cause – the SFC utility cannot access the winsxs folder (C:\Windows\winsxs) because of some issues with the folder’s security descriptors.
Step 1: Open the command prompt by following the above steps.
Step 2: In the Command Prompt window, Type “ICACLS C:\Windows\winsxs” and press the Enter key.
Step 3: Anticipate until the command is executed, then close the Command Prompt.
Step 4: Reboot your machine and run SFC again to verify if the issue has been resolved.
Solution 4: Reinstall the system
If none of the solutions worked positively for you, you can try to reinstall the system. It is the fastest way to resolve the “Windows Resource Protection could not perform the requested operation” error:
Step 1: Go to Microsoft Media Creation Tool window and select the Download tool now option.
Step 2: Accept the license agreement.
Step 3: Keep the default which is to Upgrade your PC and click Next.
Step 4: Now just follow whatever is prompted in order to complete the process.
