1. Launch the Task Manager either by right-clicking on the taskbar and selecting Task Manager, or hitting Ctrl+Alt+Delete.
2. Select “Run new task” and run PowerShell by typing “PowerShell”. Make sure you check the option to run this task with administrator privileges.
3. Once PowerShell has opened, type “sfc /scannow” and hit Return. Let it run, and if you see the message “Windows Resource Protection found corrupt files but was unable to fix some (or all) of them”, it has found some errors.
4. To fix them, type “DISM /Online /Cleanup-Image /RestoreHealth” – you’ll need to be online, as Windows will download “clean” versions of the corrupted files and replace them.
