Up until now, the Windows 7 Log-On sound could be heard as soon as the user logged on. After the 20.1.1.2 upgrade, the log-on sound is not heard until a few minutes (!) after log-on. This is a crazy situation, as the system is fairly fast.
I am of course hesitant to install the upgrade on all remaining PC's until this is fixed.
I did use the "Live Update" button several times and subsequently rebooted the same amount of times, to no avail.
I had experienced problems with upgrades in the past, but this one tops them all
