Windows Update runs into problems from time to time. It might take a long time to check for downloads or it might simply quit working altogether.
As an IT professional, you must know how to perform a full Windows Update reset when problems arise. Your first option is to access the Windows Update Troubleshooter built into Windows 10. You can access it through Start > Settings > Update & Security > Troubleshoot > Windows Update. The Windows Update Troubleshooter is also available to download online.
If neither version of the Windows Update Troubleshooter can fix the problem, it's time to perform a full Windows Update reset. You can perform a Windows Update reset fairly quickly and easily, but you must be logged in with administrator privileges to do so.
That's all it takes to execute a full Windows Update reset.
