explorer.exe as windows system application


is it safe to set explorer.exe as “windows system application”?
one security problem I can see doing that is that, if a program gets to “control” explorer.exe somehow, it can basically do anything
but I guess I’ll be alerted if a program tries to do that, so that should be pretty safe

what do you think?


I would leave it with its default settings. Suppose you install something which contains something malicious that you don’t know about. When in Installation Mode it can start explorer with no alerts because of the elevated rights of Installation Mode and the malware gets to do its thing.
