Update Windows 10 version 1909 to version 21H2

Can I Update Windows 10 version 1909 to version 21H2 (latest)?

Then Please send the useful steps to do that...

By changing windows version 1909 to 21H2 does it removes all files(music, videos, software,etc.) present in my laptop or it is safe, nothing will be deleted.

Now I am not getting critical updates for windows version 1909.

Please anybody give suggestion regarding this matter.

 

Windows 10 fails to update


When you finish testing the Avast suggestion, make sure that you restart your machine.

Then if the issue persists, please return to the trouble shooting list in post# 89

I think there are three steps that remain; the WU troubleshooter, reset WU components, and manual WU reset.

 

KB4023057 Version 21H2 appears in Windows updater for a moment

Hi

In Windows Update KB4023057 Version 21H2 appears and it wants to downloading but stops immediately at 0% and disappears.
Under View update history the update appears as Successfully installed on 9/9/2021.

I can manually check for updates and the update appears again for 2 seconds.

I run the Windows 10 Update troubleshooter. Didn't found any issues. Wanted to uninstall the update but it isn't listed under Uninstall Updates in View Update History.

Not sure if relevant; As Optional quality update available is cumulative preview for 21H2 (KB5007253). Usually I don't install optional updates.

Any suggestions?
