I have been noticing something was eating up a chunk of RAM recently, and after having messed around with the task manager i found out what it was...
Internet Explorer (iexplore.exe)
I use Google Chrome, and before that i used Firefox, so there is no reason for IE to be open at any time. I tried killing it in the task manager, but every time i stopped it, the next time i checked it would be there again, eating RAM.
I located the folder and tried to delete it, and it told me i didn't have authorisation to delete the folder, which shocked me, as i disabled UAC months and months ago.
I tried everything to get rid of the folder, or find a way to render the program inoperable, but i couldn't, i was thwarted at every turn by the UAC that i had long since deactivated.
I couldn't even find IE in add/remove programs and add/remove windows components.
So, why do i not have full control of all of my files seen as UAC is turned off? I deactivated it to prevent such situations from ocurring, and why does IE keep coming back after i kill it?
And most importantly: how can i kill IE for good? (Garlic and silver bullets do not work)
