Yesterday I ran into a weird issue when I tried to capture a Windows 10 image with sccm.
‘A fatal error occurred while trying to sysprep the machine.’
Let’s check the logfile: c:\windows\system32\sysprep\panther\setuperr.log
Hmm, the problem is related with one of the built-in application.
I didnt want to remove these apps.
In this Windows installation, the local username created for first time was ‘User’
In this time, I had an idea…what if local username was the problem?
Immediately I installed another image where the local username was ‘SCCM’. Test with sysprep…bamm, sysprep ran without error!
Wrapping up: do not use built-in usernames like ‘user’ or ‘administartor’ etc. Local username should be unique
