Windows 10 LTSC 2019 v1809 in-place upgrade to LTSC 2021 v21H1 crash

Question

Hello to all Technicians and more :)

I' trying to upgrade a notebook from Windows 10 LTSC 2019 v1809 to LTSC 2021 v21H1 but unfortunately, the setup crashes always at the end at around 95%.

I've noticed that in setup, the progress stays at 88% for a long time!

Last message is that it's going to restart the system to proceed with the upgrade and then the window suddenly disappears without any further notice...

After a restart, I also noticed that Windows boots with the generic logo and the EFI-Parition is visible for one time until I restart the system again.

System integrity has been checked with SFC and DISM without any errors, I "repaired" it with DISM anyways just in case, nothing went wrong

CHKDSK also doesn't claim any problems (3 SSDs and one external HDD)

LTSC 2021 media have been checked with SHA256

I tried to deactivate and uninstall Avast One, I also removed some drivers just in case but nothing has changed so far
BTW this is the only device where the upgrade fails!

I add the logs and EventViewer on my OneDrive for you

Eyecatcher is this line;

FatalError [0x090001] PANTHR Exception (code 0xC0000005: ACCESS_VIOLATION) occurred at 0x00007FFEBD2F12DD in C:\$WINDOWS.~BT\Sources\SetupPlatform.dll (+00000000003F12DD). Minidump attached (141193 bytes) to diagerr.xml and C:\$WINDOWS.~BT\Sources\Panther\mnd7102.diagerr.mdmp.

2nd try;

I tried again but this time, I also removed Alcohol 120% with SPTD and AOMEI including ambakdrv.sys (BSOD friendly cough)
Nothing changed so far :(

I thank you all in advance and wish you a lovely summer :)

Best regards

Answer 1

Delete C:\$Windows.~BT\

Then from an admin command prompt (search start for cmd right click Command Prompt Run as administrator ), copy and paste;

Net stop bits
Net stop wuauserv
Net stop appidsvc
Net stop cryptsvc
Del %ALLUSERSPROFILE%\Microsoft\Network\Downloader\qmgr*.dat /Q
Del "%HOMEDRIVE%\Users\All Users\Microsoft\Network\Downloader\qmgr*.dat" /Q
Del %WINDIR%\SoftwareDistribution*.* /s /Q
Net start bits
Net start wuauserv
Net start appidsvc
Net start cryptsvc
Check again for updates.

Didn't helped unfortunately :( Same error with access violation...

I uninstalled cFos just in case the network driver causes some confusion but nothing happened...

Answer 3

Problem solved!

Whatever happened, we "repaired" the system via an in-place upgrade with LTSC 2019 and then upgraded immediately to LTSC 2021....

Somehow it worked flawlessly! We don't know why but nevermind TBH ^^

Hi there,

This issue is caused by something being corrupted in the windows provisioning information. You can fix this by replacing C:\Windows\Provisioning and HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Provisioning with copies from a machine that worked. As you have stated that the update fails in only one machine try replacing this with the machines where the updates were successful.

The below thread discusses the same issue and you can try out some troubleshooting steps from this and see if that helps you to sort the Issue.
