That's a good point, Greg. I modified it to include that functionality.
I was racking my brain at lunch trying to remember where this was and I just now remembered…and then I facepalmed when I read Greg's second sentence here.
But, since I had a eureka moment "It was in Tim's repo!" I am posting it anyway 😛

If I were to use some variation of this, I'd probably also have a "ignore list" of account names to ignore, with the primary (or maybe only) member being our local admin account.
When a machine is first deployed it's not unheard of for the local admin account to be a more "frequent" user than the (new) local user.
