Pretty hard, as it turns out. I knew I was in trouble when after staring at the "start" screen for a few minutes, I had no idea how to access settings or navigate the file system to get to, say, my NAS unit or USB stick.

I have yet to go to a business as a sysadmin where they didn't use default passwords (P@ss1234, now how many businesses use that gem) which are on just about every device or local admin account.
