I was trying to customize Windows 10 with our corporate backgrounds. The target is to have the same wallpaper and the same Lock Screen Background for each user in the domain.

Normally what i did in Windows 7 was perform that modification in Audit Mode, but i'm not able to do it with Windows 10. When i try to change lock screen Background is impossible....

But i notice after the installation if i try to change the Lock Screen Account with the user i have created(with Admin Right) during the installation i will be able to customize all.

My question is i can try to run sysprep /generalize /oobe /shutdown /unattend:copyprofile.xml with the Admin User Created during the installation?
