Solved “Windows Resource Protection could Not Start Repair Service” Error

Windows 10 would have now become the part and parcel of your digital life. All the features and enhancements developed exclusively on Windows 10 are ,in fact, highly appealing. One of its major features is the System File Checker or SFC. This is mainly used to do a thorough scan on the complete file system of your PC. This can easily detect any corrupted files and the missing contents of file. Whenever you find that a file doesn’t open properly, or there are any corruptions with the file that gets downloaded from browsers, then they need to be scanned or the browser needs to be reset. This can happen mainly due to network traffic congestion or the involvement of viruses in the files. Also, another cause may be due to the improper service running behind the Windows Module Installer.

To overcome such issues, a very easy way is to open up the command prompt in Admin mode. Once the window opens up, type in the command sfc/scannow. The scan begins immediately and you will have to wait for about 5 minutes till the verification phase completes. But many a times you do this, an error given below pops up.
