how to format my hard drive without logging into os

Both ways work for me.Do you use a Windows PC and have lost your password? Do not worry! I will share two methods on how to recover your files and data from the locked PC. Hope this helps others: if you’re using an external keyboard, try logging in with the built-in one, or use the on-screen keyboard. I have to log in with the built in keyboard apparently. I’ve checked the drivers for my keyboard and Windows thinks I already have the latest drivers. This is clearly yet another bug introduced by the brilliant Microsoft Windows team. The fact that I can log in either of these two ways implies clearly what the problem is (in my case anyway): it has to do with the external keyboard. As others have said, I can also log in using the on-screen keyboard. I have not changed my external keyboard in years, and it’s been working fine for years up till two days ago. When I use the computer’s built in keyboard, I can log in fine. No one has mentioned this, but in my case I’m using an EXTERNAL keyboard. I’m 100% sure the pwd is correct (same one for a decade, no chance of being wrong). I too have now encountered “wrong password” when trying to log in after computer has been sleeping. The answers on this page are not getting at the problem. Geeks will want you to change your password from time to time for a variety of reasons but they don't know how to say that so they tell you that YOU forgot YOUR password even if you have it correctly written/typed in 10 places. Same setup, software environment, manufacturer and Windows 10 is a completely different animal between the 2. One went well whereas the other was a 2 week process culminating in a $200 purchase that, so far, has required multiple sessions with tech support over 5 months, restoration of the data partition of the hard drive from a backup, restoration of the OS partition as a manual re-install all my software. I deployed 10 over XP 2 PCs configured almost identically. I am almost too committed to Windows having cussed at Windows 95, 98, Millenium, 2000, XP and now 10.
