Had to do something similar at work a couple months ago when a Windows computer somehow ended up without a single account with administrator privileges but I replaced magnifier.exe with cmd (for some reason I even switched them around) and then opened the supercharged "magnifier" on the login screen. I also didn't use "Startup repair" but a Ubuntu Live CD. I then got called away from the computer before I could switch magnifier and cmd back to normal and somebody started using the computer again, with hilarious consequences (Note: I'm not the IT guy in this company xD)
