Windows Update stuck downloading/Installing updates in Windows 10

This can become a problem if you have not been doing your updates regularly.

I have found that the below helps to resolve the problem.

• Open an Admin Command Prompt.  To do this click start and type CMD.  Right click on cmd and choose “Run as Administrator”.  In the cmd window type the below
• Net stop wuauserv
• Net stop bits
• Once both services have stopped move onto the next stage.  If the wuauserv service doesn’t stop do the bits one and then retry the wuauserv.
• Open file explorer and browse to C:\Windows\SoftwareDistribution.
• Delete all files within this directory.  If they don’t delete make sure the services are still stopped as Windows 10 will try and automatically restart them.
• Once the directory is empty go back to the CMD window and type the below
• Net start wuauserv
• net start bits
• Retry your windows updates and the should install.  You may have to do this more than once.
