that you probably haven’t ever looked into. Usually you won’t need to bother with these, but if they get corrupted somehow, it causes problems. Blue screens, weird error messages, and crashes can all be caused by screwed-up Windows system files.

Thankfully, there’s a built-in Windows tool called the System File Checker (SFC) that will automatically scan and try to fix for damaged Windows files. To use it, open an Admin Command Prompt by typing cmd into the Start Menu, then right-clicking on it and choosing Run as Administrator. Type the following command to run the SFC:

sfc /scannow

Open a Command Prompt as above, then use this modified SFC command to scan the external drive instead of the unaffected computer’s internal drive:

Before you do this, open This PC by pressing Windows key + E and confirm which drive letter the external drive is at. Replace the d in the command above with your drive’s letter to scan the correct one. Give it some time, and the command line will produce a message with the results.

Using a Windows repair drive, you can also get into a Command Prompt and use this modified command to scan your internal drive using SFC. If SFC can’t solve your problem, check out further troubleshooting for a corrupted Windows 10 installation
