I had a problem with a program that I thought I'd be able to solve
by doing a system restore.
The side effects however were too severe and made me undo the system
restore. After the undo, the problems weren't solved at all...
My computer boots as fast as it did before, but almost none of my
startup programs still start up. (in the task manager under the tab
where the startup items are, they're still listed and active)
If I shut down or restart, my system takes about 3-5 minutes to do
so (it stays in the windows 8 shutdown screen)
Programs take quite a while longer to boot up (where Word booted up
in about 3-4 seconds, it now takes about 20 seconds, the same is true
for Powerpoint and Visual Studio).
The last problem (that I currently know of) is that Outlook 2013
stays stuck at the splash screen and says 'loading profile'. I can't
get it to open at all, even in Safe mode it won't budge...
What can possibly cause this kind of behaviour? I already scanned
for registry problems with CCleaner and for malware with Malwarebytes.
edit: More problems found, if I try to go to the Windows Update
screen, explorer hangs, and when I try to run things like DISM or
sysscan in an elevated cmd, it doens't even start to do
