Windows 10: windows 21H2 update

So for the past day or so ive been trying to update my Windows 10 pc to the latest version which is 21H2 KB5012599 It download and start to install. Once it starts installing it will go to 20% for abit and eventually get to 100% before it fails to install it. I keep getting error code 0x800f0900 and ive even tried using the windows trouble shooter but it says everything is fine. But everything is the opposite of fine for my computer since this update came out as its slowed my computer down dramatically. All i want is to return my computer back to its normal speed.

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?

 

Windows Updated(16299.309).KB4088776 Restart is required to complete.

Hi dalchina. Good news, I followed your suggestion and reinstalled the update and now it appears as "installed correctly" *Biggrin Maybe it was not necessary to run the Windows Update Troubleshooter or maybe if necessary. But using it I do not think it could have worsened something. The installation was very fast, unlike the first time it showed step 1 and step 2 completed.

Thanks for the suggestions and for the time to respond Best regards.


And thanks for the tip of that program, I'll have it on my list.
