Are you having problems running the System File Checker?

Windows Resource Protection restricts editing of the already-installed folders and files that come along with the operating system. This is in an attempt to maintain the integrity of the operating system.

However, in one way or another, system files might get corrupted. The Windows system may start to crash or cease functioning correctly.

On such occasions, use System File Checker (SFC) to inspect and repair corrupted system files.

The SCF utility readily detects any corrupt files, missing contents of a file, and restores the healthy ones from a compressed folder in your system.

However, many folks report that when they execute the “sfc / scannow” command, the error of “Window Resource Protection couldn`t start the repair service” pops up.

The good news is that the above error is easily fixable. Just keep reading the guide.

If the SFC utility doesn`t quickly check and restore your system file, take it easy. It isn`t difficult as it may appear to correct the error.

The fixes below cover the basics of fixing this error. One of them should be able to fix your problem.
