Windows update is trying to install the following update and failing with error 0x80070643
“Security Update for the remote code execution vulnerability in Visual Studio 2013 Update 5 (KB4571480)"
I was able to determine the cause by trying to install the update manually from the Windows Update Catalog. Doing that clarified the error
The update is failing because | DO NOT have Visual Studio 2013 on my PC (I have VS2010. VS2015. and VS2019: but, not VS2013).
Note: I checked my system and I do have the VS2013 redistributables installed; but, this update is for VS not the redistributable.
I also tried using the Windows Troubleshooter and following the procedures on https:/iwww.howtoedge. com/fix-update-error-0x80070643-on-windows-10/
Note: After deleting the SoftwareDistributian folder Windows Update just downloaded it again and then failed the install again.
