Can't get onto my computer

[Guest]

I just got a computer given to me and before I can get
onto Windows I press cntrl alt delete and then I am
supposed to type a username and password but I do not know
them. How can I get onto my computer?

Try:
Username: Administrator
No password

Username: Administrator
password: password

Wipe drive and do a clean install. (If PC was given to you, you will
proabably want to do this anyway)

Or use admin tools to boot, follow on screen prompts, provide username,
Admin password will be displayed.
