This is my first account and I don't have enough rep points to comment there, apparently. So I have to make a new question...
Noticed in my lab (1809) that a logon script seemed very slow to process. At work we're running 1703 and as far as I can tell logon scripts are executed quite fast.
Slow as in about two minutes, not the full five minutes, however.
I tried setting Configure Logon Script Delay to Disabled, however it seemed to make no difference in logon script delay. It kept launching about 2 minutes after desktop was presented.
