My Windows 7 desktop PC, built by me, started acting very weird in the last couple of days. I use it quite often, about half of the time through TeamViewer. Explorer would crash and restart randomly, almost always through TeamViewer. This made me suspect that TeamViewer was the problem but I have reproduced it with and without TeamViewer several times. The only way I can seem to get the problem not to occur is by booting into Safe Mode.

I have used CCleaner and Malwarebytes to make sure it wasn't a registry error or malware causing the problem, and I have tried the fix in the seemly related issue here as well every other fix I have found online including removing security updates KB980408 and KB2926765 as well as using "sfc /scannow" and a bunch of other things I can't remember.

More recently when I try to start explorer it is popping up a small window that says "Personalized Settings" on the top, but is completely empty and crashes instantly. The only way I can get it to disappear is to kill the explorer.exe process. I wish I could take a screenshot but I can't seem to open paint or even find the exe. I have tried restarting it, I have tried starting it while the personalized settings window was open.

I have come up with two lists of processes the first is the list of active processes when I boot into safe mode and explorer seems to work fine. The second is the list of processes that I can narrow it down to in normal boot and still replicate the problem. There is one process that I can't seem to close. NisSrv.exe which is describes as "Microsoft Network Realtime Inspection Service". When I try to close the process NisSrv.exe it says "The operation could not be completed. Access is denied." When I try to close the related service it gives the same message.

Another probably unrelated error that I seem to be getting pretty often.

Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60
WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage > 99"
could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. 
Events cannot be delivered through this filter until the problem is corrected.

My explorer tab in Autoruns seen below along with the error when I try to uncheck something. I should add that I seem to be able to disable shell extensions with ShellExView but I still can't get explorer to start correctly.

EXPLORER SHELL UPDATE - See screenshot below I can access the explorer right click menu through a file manager I downloaded called NexusFile, but still no luck starting explorer.
