How to Reset / Recover Forgotten Windows NT / 2000 / XP / 2003/VISTA Administrator Password?

Forgetting your Windows administrator login password. With no way to get into the system, you can’t even perform basic maintenance, let alone a thorough tune-up. Formatting is always an option, but we consider that a last resort. (Plus, guess who’s going to have to help reinstall all the programs lost after a wipe?) But all hope is not lost. There are a few ways to actually retrieve a lost Windows account password. Read on, and we’ll show you the light.

1st Method:

The first thing which you check if you forget login password. When we install Windows, it automatically creates an account "Administrator" and sets its password to blank. So if you have forget your user account password then try this:

Start system and when you see Windows Welcome screen / Login screen, press ctrl+alt+del keys twice and it'll show Classic Login box. Now type "Administrator" (without quotes) in Username and leave Password field blank. Now press Enter and you should be able to log in Windows.

Now you can reset your account password from "Control Panel -> User Accounts".

Same thing can be done using Safe Mode. In Safe Mode Windows will show this in-built Administrator account in Login screen.

2th Method:

There are a lot of Windows password revealers and crackers available.

This tool only works on NTFS partitions, but it works great! You can even use it to copy data from one place to another. But it is not for free.
