[SOLVED]"Fail Fast Exception" error

with or without MRP.
if it's with i've met him a few times but not for since my last tests.
Look on the thread, I think this has been discussed.

 

It seems to me that it was Enthousiast who was the first to report the problem. Here.
Random and infrequent problem for me. No solution found.

 

Im not 100% sure but it could be either a code fault in explorer.exe more so with w11.

Or too many context menu entries. But that would appear every time so doubt it that.

Could be a 3rd party app or dll etc that is installed which can interlink with explorer.exe that confuses something in the os.

All speculation and maybe a error introduced into explorer shell by ms via a later cu.

My approach is different. I never modify install.wim.
I only use MRP and SetupComplete.cmd for custom Windows installations.
This allows me to limit my research in case of problems.

 

I really have an atypical way of proceed. Like the others, it has its pros and cons.
I use standalone silent installers which I place in a specific folder according to my needs.
