Hi all,
I have been trying to install KB4579311 for several days now. Every time I try to install it, I get the following error code: 0x800f081f
I am using a custom-built PC that has worked fine for the past 6 years and other updates are able to be installed - just not KB4579311. I am currently on Windows 10 Version 2004 OS Build 19041.508. I am running Windows Home 64-bit.
I have looked up this error code and done many different things that MS support has asked me to try, and none of them have worked. I have:
- Manually installed it from the Microsoft Update Catalog and ran into the same problem
- Manually installed it after deleting the SoftwareDownload folder under C://Windows and ran into the same problem
- Used Windows update troubleshooter and it could not even diagnose my issue
- Used a Dism /Online /Cleanup-Image /RestoreHealth command through command prompt and PowerShell, which got me the following error:
"Error 582. An illegal character was encountered. For a multi-byte character set this includes a lead byte without a succeeding trail byte. For the Unicode character set this includes the characters 0xFFFF and 0xFFFE
Any help would be greatly appreciated!
