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!

    Hi Min,

    Got the logs. Yes, you can remove them.

    1. Please share "C:\Windows\Panther" as well.
    2. Export the "Administrative Events" log from the Windows Event Viewer. To do so, open Event Viewer, navigate to Custom Views, and then select Administrative Events. Right-click on the "Administrative Events" entry and choose "Save All Events As..." to save the log as a .evtx file.

    Isn't there a Panther folder inside that ZIP thing?

    Am sure I saw one.

    Will do it, but not right now plus it will take a while to work out how to do that through Google and reading it a few times back and forth as I did with that batch file one.

    Is 1 and 2 two different requests or just how to get the Panther thing you want.

    Please tell me there isn't anything further needed because I think a clean install is the answer and finding an audio driver replacement.

    Ok. The component store is very much corrupted. It should have been fixed during the repair install. This makes me wonder if the repair installation failed and silently rolled back. Inspecting the setup logs should help.

    For some reason I can login to this site on my PC, but not Microsoft or Microsoft OneDrive.

    Logging in on the phone seems to work fine though.

    So, everything had to be done from PC to phone...again.

    SetUpLogs.zip.

    Thanks...

    Please see my previous post. Share "SetupLogs.zip" as well.

    Didn't see this part.

    Will have to do it another time (maybe tomorrow) as I only use my PC for Netflix and YouTube not things like One Drive or Microsoft - just online streaming.

    Am not doing three overnights in a row.

    I had to find a way to put that last Zip folder in my phone somehow to post it here and that took a bit of working out as have never used One Drive before (that I can think of) nor a lot of this PC stuff for Windows or Microsoft.

    Microsoft should have left it at XP or Windows 7.

    Anyways, will do the next part later and post it here when I do.
