Hi everyone. First, my english is not so good.
Before two days i set password on my windows, but i forget it. And now i can't log on in to windows. What can i do? PLEASE HELP ME. try this, reboot your PC and as SOON as it starts to reboot start pressing F12 you should come to a screen that gives you mulitpe otipns on how to start up. Go ahead and start up in safe mode, it might take awhile to come up becasue it has to go thru its process. When it finally comes up you should have two OPTIONS to login with
1.ADMIN
2.your user name
click on the admin name and it should let you right in.
now to fix your password got to -> start>CONTROL panel>users accounts>click on your name and reset your password.

When done kust reboot normally and try to login.Restart your computer and KEEP tapping F8.
Choose Safe Mode.

Logon with the inbuilt administrator account.
Click on Start, Run and type in control userpasswords2
Choose your user account.
Click on Reset Password...
