I did a fresh install of Windows on this Desktop I am hardening After running the script and reseating the device when I log into my Admin user the desktop keeps crashing and a prompt saying that the system detected an overrun of stack-based buffer in this application. Are there any idea on what might be causing this I have done 3 fresh installs just to make sure it wasn't an application that was causing the issue

I am using Windows 11 24H2 and I read the readme file saying to create a local user. However I am confused on if I need to create another local user after the initial setup.

You should only have to create local accounts in lue of any accounts originally set up with a Microsoft login with email.
You don't need to create multiple accounts to replace one.
