Windows 10: Cannot download and install "Update for Windows 10 Version 21H2 for x64-based Systems...

Hi, my computer wont download and update for Windows and is giving me error 0x80070643. I've tried a bunch of different fixes Clean Boot, fixing .NET failed, etc. and it still gives me the same error. My antivirus reports nothing fishy, so I'm assuming there's nothing wrong on that end. My computer has also been having some weird issues lately Task Manager and File Explorer crashing and 'Not Responding', but I don't know if the issues are related. Thanks in advance.

Maybe try with the Windows update mini-tool, found here http://www.techpowerup.com/forums/t...dows-10-automatic-updates-and-spyware.218745/ , thanks to Mussels. it installed perfectly for me last night.

 

Windows 7 Ultimate (64) Security updates not installing.

I have been having problems in installing the updates that I have listed below. For each update I attempted to install them individually but they would not install. I also downloaded the SURT 6.1 KB947821 v27. The problem has been going on now for about 2 months. (whenever the issue with the updates comes to mind I am never near my pc). Thank you in advance.
