A simple restart command doesn't perform the update step, just the restart, so the update doesn't get applied.
This has been an issue for a very long time with windows. I am surprised it hasn't been fixed yet. It's really annoying
Well, at least with Win 7, a standard reboot applies updates. At least, I think it does. The main difference between Win 7 and 10, is that they have switched to the osoclient.exe to manage the updates.
I'm pretty sure server 2008 and onward had the issue. I don't remember dealing with it on workstations
I still have a 2008 R2 box and can test it on the next go 'round. I won't have it much longer, as I am dumping it prior to EOS.
LOL - Didn't make this cutoff. Next week, hopefully.
