Unusual Files in C Drive After FAILED Windows Update Attempts!

Windows 10

Just wanted to give it a fair go one more time by trying to fix problems myself, but still a major failure with Windows Updates.

Also, there doesn't seem to be any issues with the PC itself that I can find using what is available - it really does seem to be corrupt Window Updates.

Error Code: 0x80070057

Reset was done back in February, but didn't work. The only Antivirus third party programs on it before then was Kaspersky and AVG.

AVG was removed in the last part of 2024 and then reintroduced after the reset then removed again when told to remove everything by Microsoft Support.

Current Anti-virus is disabled.

Over the last 48 hours:

a: Scannow came back clean.

b: Chkdsk found nothing.

c: DISM also didn't resolve any issues as none found.

d: Ample storage in C Drive like 500 GBs.

e: Managed to rename SoftwareDistribution folders after the net stop ... net start steps, but made no difference.

f: Troubleshooter had pending restart at first, but since then troubleshooter detects no issues.

g: Have manually downloaded the updates from February and April (can't find anything for March) only these won't install either.

h: With Windows Update ERROR ENCOUNTERED does come up and Troubleshooter still detects nothing.

i: No malware or anything as that was checked prior via someone in the Microsoft Community and I still do checks myself.

j: Under RegEdit after exporting changed the values to 0 for Window Update Ux like:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsUpdate\UX]

"IsConvergedUpdateStackEnabled"=dword:00000000

h: Diskcheckup found no issues.

On checking C Drive about the storage space as I was wondering if maybe I was missing something**,** just in case, I discovered these folders or files and was wondering if my PC is now compromised or these are a tell tale sign of Windows Update being corrupted or Other as these have only appeared in the last 6 hours or so.

NOTE: Will be doing a clean install at some point, but not just yet as need to copy some stuff over that I want to keep and as it may take several hours...

There is one or two others like below as well and all dated the same.

Thanks in advance!
