Sysprep fails on Windows 10 20H2

Question

Greetings,
I am doing my first build and capture for Windows 10 20H2 and that capture step fails with the generic 4005.
The sysprep log says 'failed while deleting repository files under c:\programdata\microsoft\windows\Apprepository.
The setupact logfile has a number of errors referring to 'appx' applications - '0x20 and 0x91 error while deleting file'
Anyone know how to fix this please?
Thanks
David Z

Thanks - Ill go through that when I get some time.
The scenarios they mentioned dont cover mine from what I can see.
I did an OSD loading the vanilla version of 20H2 and installing only Office. I then applied all the updates and then attempted the capture.

Hi,

Thanks for posting in Microsoft MECM Q&A forum.

May we know what version of ConfigMgr and Windows ADK you are using? If you are running a older version, please upgrade to ConfigMgr 2006/ConfigMgr 2010 and Windows 10 ADK version 2004 to support Windows 10 20H2 as a client.

Here are some articles for your reference:

Hi, Another tip..
I would start with

1. removing Office
2. make sure that the builtin-apps doesn't update sounds like that could be the issue, While you install Office apps starts to update.
   Easiest is doing a capture on a VM without internet connection or stop the apps from updating..

Then when/if that works add back Office and test again.

Answer 5

Please go to my sysprep guide here
Under

“known problems that can happen :“

You’ll find a remove command

“remove-appxpackage whateverthenameisoftheapp”

Take another look in setupact file and copy the name of the appx and replace whateverthenameisoftheapp with the name, paste the whole thing in power shell after removing try again. if sysprep fails again look in that setupact file again and copy the name of the offending app again, repeat the steps till it works... please leave a comment on my guide if it works and mark this question as solved

If the above doesn’t work I’m out of ideas, you’ll have to start over, let this be a lesson not to use internet on a device you have in Audit Mode!

Good luck
