The Email said as this:
Reinstalling windows 7, no password?
I bought a laptop from somebody, and stupidly, I didn't realize that when they were demonstrating how it functioned that it was logged into Guest. The administrator has a password and I don't know it. I have no password reset disc, or anything like that, and I can't do system recovery, restore, or even use the command prompt because only administrators can do that!
I read that I can reinstall windows 7, but how would I to bypass Windows 7 password? Please help!
Answer 1: If you got a windows 7 disk with the computer, all you need to do is put it in the laptop and on start up press F12 or F1, this might depend on the computer, and choose to boot from a CD.
If you dont have a CD labeled Windows 7 or Restore Disk, you will either need to go get this fixed at a computer repair shop or buy another disk from the electronics store.
Answer 2: See if you can run this command in the run. type it in the search bar down at the bottom
if it works click on the administrators account and set a new password
