So after that, I tried booting it up on same OS version that it last worked with it, same issue. :( So, being weary, and would rather play it safe, I decided to just make a new Office 2021 layer, then did the RunOptimizer part to it.
I spit out a template after all that, and i can't even login to my template... It stays at the Ctrl + Alt + Del screen, and only flickers when you hit Ctrl + Alt + Del. FUN!
After some extensive troubleshooting doing process of layer elimination, I found that my View Agent layer was the culprit. So, I re-did that layer too! And I had just re-done this layer about a year ago too!
So now my template is useable (after some brief RPC errors in regards to domain joining), and we'll see if I can recompose some guniea pigs and see what else is broke! :)
