The good news is that most problems can easily be repaired with just a few steps. Windows 10 is the most popular operating system in existence, which means that its users will encounter some of the most common problems at some point. It will provide a summary of its activity when finished, as well as a destination where you can find the log files. While it runs, the System File Checker will look for corrupted files and attempt to repair them if possible. The process will take some time-up to several minutes depending on the size of your drive. Just type in sfc /scannow and sit back and wait. While it may look intimidating, it isn’t. Open the command prompt by typing Windows + R and then cmd.
