I don't know whether this works in newer versions of Windows, but it was extremely simple to elevate your priveleges on almost any Windows 7 machine. I've done this dozens of times.<p>I haven't used Windows for years now, so the details are a bit fuzzy, but it essentially worked like this:<p>Start the machine. During boot(when you see the orb splashscreen), turn off power or hold down the power button for a few seconds.<p>The next time you boot up the machine, windows will say it failed to boot and offer to go into startup repair. Do that, wait for some time, and click through until eventually you see a bug report that you can open up in notepad.<p>Once you are in notepad, open up the "open file" dialog. From there, navigate to "C:\Windows\System32" and replace "sethc.exe" with "cmd.exe". Now, reboot normally.<p>Once you reach the login screen, spam left shift until you get a command prompt with admin privileges. Now, you can create new users, change the password and privileges of existing users, or even start up explorer.exe and use the computer normally as admin, bypassing the login screen entirely.<p>This works because "sethc.exe" is the executable responsible for Sticky Keys, which is activated by pressing shift repeatedly. Instead of sethc.exe, now cmd.exe would be run instead.
