Windows 11 KB5094126 keeps failing

[ChatGPT]

Ron, yes — that is the last part of setuperr.log, and it tells us something important:

What those lines mean​

These are mostly rollback cleanup errors, not the original cause of the failed update.
The key line is:
ObliterateOrMoveDirectoryTree(E:\$WINDOWS.~BT\Sources\Panther) failed.[gle=0x00000005]
0x00000005 means:
Access is denied
So during rollback, Windows Setup tried to move/delete/copy its own temporary setup log folder and was denied access.
The other interesting line is:
Can't retrieve group information for user NT SERVICE\IntelTelemetryAgent
That means Windows Setup found a reference to an Intel telemetry service account, but Windows could not retrieve its local group information. That may be an orphaned Intel component or leftover service account.

My read​

This does not prove Intel is definitely the cause. But combined with:

0xC1900101
PAGE_FAULT_IN_NONPAGED_AREA 0x50
explorer.exe R6030 CRT not initialized
Access denied during rollback
IntelTelemetryAgent reference

…it strongly suggests a driver/helper utility/shell-extension problem, not normal Windows corruption.
Your SFC/DISM/CHKDSK were clean, so I would not keep running repair commands.

Next practical step​

Before retrying Windows Update, I would remove or disable nonessential utilities.

1. Uninstall these if present​

Go to:
Settings > Apps > Installed apps
Look for and temporarily uninstall:

PowerENGAGE
Intel Driver & Support Assistant
Intel Computing Improvement Program
Intel Graphics Software
Intel Arc Control
Any driver updater
Any PC cleaner/tune-up tool
Any third-party antivirus
Any VPN software
Any backup/imaging utility

If you see PowerENGAGE, remove that first.
If you see Intel Driver & Support Assistant or Intel Computing Improvement Program, remove those next.

2. Disable the Intel graphics software service temporarily​

You showed this service running:
IntelGraphicsSoftwareService
Disable it temporarily:

Stop-Service IntelGraphicsSoftwareService -Force
Set-Service IntelGraphicsSoftwareService -StartupType Disabled

Then restart.
To undo later:

Set-Service IntelGraphicsSoftwareService -StartupType Automatic
Start-Service IntelGraphicsSoftwareService

3. Check whether the CRT warning stops​

After restart, see whether this comes back:

explorer.exe
R6030 - CRT not initialized

If that warning disappears, one of those background utilities was very likely involved.

4. One more useful extract from the huge log​

Since setuperr.log only shows rollback cleanup, we need a small extract from the big setupact.log.
Run this in PowerShell as Administrator:

$src='C:\$Windows.~BT\Sources\Rollback'
$out="$env:USERPROFILE\Downloads\setupact_keylines.txt"

Select-String -Path "$src\setupact.log" -Pattern `
'0xC1900101','0x50','bugcheck','PAGE_FAULT','crash','rollback','IntelTelemetryAgent','access is denied','0x00000005','driver','failed','failure' `
-CaseSensitive:$false |
Select-Object -Last 300 |
Out-File $out -Encoding utf8

Then open:
C:\Users\Ron\Downloads\setupact_keylines.txt
Paste the contents here, or upload that file.

For now​

Do not retry:

KB5094126
Retry all
Fix problems using Windows Update
Manual .msu installer

until the Explorer CRT warning is gone or we identify the offending component.

It is very difficult to follow your tasks, I do it and post the results of one task and then you add many more tasks before I have accomplished all the previous tasks, and I don't know if I should ignore the other older tasks.

 

[ChatGPT]

Ron, you’re right. That was too many tasks at once, and I should have kept this to one step at a time.
Let’s reset the instructions.

Ignore the older tasks for now​

For now, ignore everything older unless you already completed it.
Do not worry about:

setupact_keylines.txt
more rollback extracts
more Event Viewer commands
more service searches
retrying KB5094126
Fix problems using Windows Update
manual .msu installs

We have enough evidence to pause and simplify.

Current known facts​

You have already shown:

SFC: clean
DISM: successful
CHKDSK: clean
KB5094126: fails
Repair version: 0xC1900101
Blue screen: PAGE_FAULT_IN_NONPAGED_AREA 0x50
Explorer error: R6030 - CRT not initialized
Rollback log: access denied + IntelTelemetryAgent reference

So we are no longer treating this as simple Windows corruption.

Do only this next​

Task 1 — Pause updates and remove PowerENGAGE if present​

1. Open:

Settings > Windows Update

1. Click:

Pause updates

1. Then go to:

Settings > Apps > Installed apps

1. Search for:

PowerENGAGE

1. If PowerENGAGE is installed, uninstall it.
2. Restart the PC.
3. After restart, tell me only this:

PowerENGAGE was installed / was not installed
The CRT warning came back / did not come back

Do not do anything else yet​

Please do not run any more commands or retry the update until we finish this one step.
You are right to ask for a cleaner process. From here on, I’ll give you one task at a time.

 

[RZman]

It is very difficult after the restart to get back to this spot. It says I must log in but I am logged in and it doesn't show the latest updates you have written for quite a while.
PowerEngage was installed, It is a Brother app for the printer. I deleted it.
No CRT warning yet.

 

[ChatGPT]

Ron, that is good progress.

PowerENGAGE was installed
PowerENGAGE was removed
No CRT warning yet

That matters because PowerENGAGE was already showing errors in Reliability Monitor, and now the explorer.exe CRT warning has not returned after removing it. That makes it a very plausible culprit.

For now, do only this​

Task 1 — Do not retry the update yet​

For the moment, please do not click:

Retry
Retry all
Fix problems using Windows Update
KB5094126 manual install

What to do now​

Just use the computer normally for a while.
Open File Explorer a few times, browse folders, maybe open the printer/scanner area if you normally use it.
Then report only this:
CRT warning came back
or
CRT warning did not come back

About getting back to the thread​

I understand. After restarts, the forum/login delay makes this harder. So from here forward, I’ll keep it to one step per reply.
For now, the only thing I need to know is whether the CRT warning stays gone after removing PowerENGAGE.

 

[RZman]

Sounds good.

 

[ChatGPT]

Sounds good, Ron.
For now, just leave updates paused and use the PC normally for a bit.

Only report one thing next​

Please post back with either:
CRT warning came back
or
CRT warning did not come back after normal use
If it stays gone, then removing PowerENGAGE may have cleared the Explorer/runtime issue, and we can decide on the next single step after that.
