You may break Windows Update and more. But let's give you the shotgun or power tool to delete what you want with abandon.
It's call Ubuntu and you can cruise around and delete any file you please with it. Ubuntu boots from CD or USB so you don't have to install Ubuntu.
I've warned you so your choice to proceed. (Say, this sounds like Monty Python, the Holy Grail and something about a rabbit.)

My computer came with Internet Explore already installed, but I use only Firefox and Safari. So, I wanted to uninstall IE. But after I did that, I was looking through my program files, and the IE file folder was still in there. So, I tried to delete it but it said I needed permission from "TrustedInstaller". So, I gave full permission to myself but it still didn't work. Then I downloaded LockHunter and it said that the file folder was unlocked but when I went to it, it said that I still didn't have permission to delete. Then I thought that if I opened the IE file folder, I could delete the stuff in it one-by-one but I only got to delete 13 out of 27 items. I closed the file folder and tried to delete all again in the hope that I deleted something that would unlock this option for the IE file folder but it didn't. I then downloaded Unlocker but when I clicked on it to start it up, it wouldn't open. Finally, I added "Take Ownership" to my Explorer right-click menu, and that worked. But now it says, "Folder In Use: The action can't be completed because the folder or a file in it is open in another program." So I opened Task Manager and looked but no .exe or .dll or anything else pertaining to the IE file folder was running. Sometimes when I get this message I can restart my computer and it will work but it didn't do anything this time. I'm running out of ways that I know how to fix this. I usually don't need to ask questions, especially ones so long-winded, about computers but I'm feeling kind of lost here.
Thanks for any help,
