It's no secret that Windows often fails to install the updates released by Microsoft. In most cases the problem comes from Windows Update. Many times a restart of the service can solve the problem, and continue the process of installing the updates.
This can be done in a variety of ways, including your service system list (look for Services in the Start menu and press Enter, find Windows Update and select Restart), but there is also a much easier way from the Command Prompt or PowerShell.
Below we will see two different commands. To run them you will need to open the Command Prompt or PowerShell with administrator privileges. (In the search, type cmd or powershell and when the icon you are interested in appears, right-click on it and "open as administrator")
First of all, we will stop the Windows Update service: copy and paste the following command:
net stop wuauerv
If you restart your computer, Windows Update will start automatically. Otherwise, you can use the following command to start the service:
net start wuauserv
The above commands are only for restarting the Windows Update service, and not for resetting, as a reset is a much more complex process that includes many other commands.
We know that a simple reboot of Windows Update often helps Windows 10 updates that are stuck during the download process. The above solution does not work in 100 percent of cases.
In fact, it's proven that sometimes it does not work when they try to install cumulative updates, and in that case the only thing we can do is wait for Microsoft to provide a solution.
