A bit of an odd request I gather, but for reasons too deep to go into detail here I need to replace my explorer.exe in the C:\Windows directory.

I have tried doing it myself, through the GUI and command prompt (ran as administrator) but I get access denied. It seems that being an admin on your machine is not the highest permission level after all, and only Trusted Installer can modify the file.

Does anybody know a way that works? I was about to boot into safe mode and try it but wanted to get some feedback before I do anything in-depth.

Thanks.
