I have read through the posted articles/questions. None of them seem to fit this issue.
This is the second time I have installed KB2919355 update. It is also the second time the result was this problem. Each time, I had to do a Checkpoint Restore to get the system back to usable state.
System - HP Laptop - (can't get full details, system is doing the Checkpoint Restore)
Quad-core I3 processor, 6 GB RAM, 750 GB HD
Windows 8.1, fully "patched" prior to this update.
I installed KB2919355. It appeared to go well. System restarted after the install and comes to the Login Screen. Once you login, it takes you straight to the desktop, which I don't mind. However, when the desktop loads, it appears to be okay, but once you try to open anything, the desktop goes into a continual reload cycle, i.e., a loop. It does not reboot. It just continually reloads the Desktop. Generally, it won't stop this loop until you force a reboot. I was able to start the Task Manager. The Wireless connection appears to be running and "talking" to the internet. The CPUs are running at about 33 to 43 percent utilization. Disk operations are pretty high. I suspect these are caused by the continual reload of the Desktop.
I was able to the PC Settings options after several frustrating attempts. CTRL-ALT-DELETE works, which is how I got the Task Manager started.
After the Checkpoint Restore, I cannot find anything that seems to be the cause of this problem. To be candid, I didn't expect to find anything because of Checkpoint Restore. I tried booting to Safemode. No luck.
You cannot load the Metro "screen" or get to it with the keyboard.
The system was fully "patched" up to KB2919355, prior to the Checkpoint Restore. All the problems start AFTER the KB2919355 install.
Again, this is the second time I have tried to install KB2919355. I have gotten the same issue after each install. Each time, the Checkpoint Restore was how I resolved the issue.
I am not green at this. I've been in IT Support, primarily UNIX, Windows Server, and Database support for quite some time. This one has me stumped.
Does anyone have any ideas or thoughts? I will get the system details after the Checkpoint Restore completes.
