KB4480955 (2019-01 Preview of Monthly Quality Rollup for Windows 7 for x86-based Systems) and a MSE definitions update got installed on my Win 7 Pro+SP1, 32-bit PC via Windows Update tonight. And then the "fun" began...
The PC says updates both were "successful" but... PC taking a very long time to reboot. "Please Wait..." followed by "Welcome..." with a few black screens before it finally gets to desktop after ~2-3 min.
There's a warning popup saying the "Windows Event Notification Service failed to start and only administrator users will be able to log in. Normal users will not be able to log in."
Also taking ~4-5 min before the Windows Audio Service starts and the red X over the speaker icon on taskbar disappears.
Rebooted 3-4 times but still the same issues. A System Restore point appears to have been set prior to tonight's updates but I haven't tried it yet...
Anyone else with this problem?
My advice: DO NOT install this update..!
