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. Don’t worry, you can fix it with the methods here. Read along to find how…

Try these fixes:

  1. Run SFC in Safe Mode
  2. Run CHKDSK
  3. Bonus Tip

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.

3) Tick on Safe boot in Boot and click OK.

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.

Bonus Tip

Updating drivers should always be your go-to option when something goes wrong with your computer or system. Whether you choose to update the device drivers manually, using Windows Update, or you use a trusted third party product, it’s essential that you have the latest correct device drivers for your operating system at all times.

If you’re not comfortable playing with device drivers, we recommend using  Driver Easy. It’s a tool that detects, downloads and (if you go Pro) installs any driver updates your computer needs.

To update your drivers with Driver Easy, just click the Scan Now button, then when it lists the drivers you need to update, click Update. The correct drivers will be downloaded, and you can install them – either manually through Windows or all automatically with Driver Easy Pro.
