v1607: Can't disable last user auto login

Before v1607, I used the gpedit logon script to disable the automatic login of non-passworded accounts. It's been fine for all the time I've been with Win10 since release.
Specifically:

Code:

Name: C:\Windows\System32\reg.exe
Parem: ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\UserSwitch /V Enabled /T REG_dWORD /D 1 /F

Since v1607 hit, it has stopped working. So I tried this instead, and the keys/strings were already set as it says so on the guide--so nothing to do there.

Does anyone else have any suggestions? Other than adding a password to this one account or having to type in a username/path to login (this account is for family members). Or did Microsoft bork something again?

That's what I was afraid of was going to be the only option. Oh well, thanks for the input. They always break one thing and fix another...
