- opening a folder from uTorrent ('Class not registered')
- opening Network and Shering (dosen't open)
- opening System window (same)
- opening most of my Control Panel windows
I found a lot of solution that didn't work for me, but the only that did was on google chrome's bug tracker in this post, response #9.
The solution just repairs all the dll's on c: drive, if you have Windows installed on a difrent partition just change C: to whatever letter is your windows partition.
I recommend reading the post before running the command just know the risks and what to expect.
FOR /R C:\ %G IN (*.dll) DO "%systemroot%\system32\regsvr32.exe" /s "%G"
