1. I get a data execution prevention: explorer.exe error click ok and explorer shuts down. (start bar icons etc)
2. (some times) I get a buffer overflow (I think thats what it is) error for explorer and the effect is the same as 1 if you click ok.
3. I noticed some pop-ups so I started windows defender and it wouldn't update properly. So I went on to the microsoft website and downloaded the newest version and while
attempting to install it I get this error: The windows installer service could not be accessed (I get the same error for all .exe s requiring the "Windows Installer Service")
please help I'm going insane :
