Hey guys, major problem here. I've removed the authui.dll whilst trying to mod windows 7, yes I know I shouldn't...

Anyway I can't put the file back because of the windows 7 security permissions, and because I've got UAC set to max settings, I can't edit the permissions to put the file back in. Can someone please help me ASAP please!

I don't have a spare disk on hand, which means I'll have to run an ISO from a USB but I don't know how. Please help me guys!

LC have a look at this http://www.sevenforums.com/tutorials/219487-clean-reinstall-factory-oem-windows-7-a.html

You need to make sure to pick the right version of 7 nothing with "old" or "N" against it and in the right language.

The ISO link Windows 7 Direct Download Links, Official Disk Images from Digital River has the OS's on it and in my pic is the list to pick from just look for the olds and N's they are old and the N means there is no Media Player in it.

But read the tutorial thoroughly first!
