We tend to have lots of passwords at work, online and at various computers. So to save yourself from a locked out situation, we recommend that you create a password reset disk.
In this article, I will share with you a very simple method to create a Windows 7 Password Reset Pen Drive. So next time you are locked out of Windows 7 at the login screen, you can plug in this USB pen drive in your computer and reset the Windows Password.
To create a Windows 7 Password reset pen drive, I advice to have a small capacity pen drive which is cheap and you should keep it at a safe place, but not so safe that you forget where you kept it when you need it sometime in future.
Follow these simple steps:
Step 1. Insert a pen drive (backup any data if present on the pen drive and delete everything). Then go to Windows 7 Start Menu and type “create password reset disk” in the start menu search and launch the program “Create a password reset disk ” which will be highlighted in the search results.
Step 2. Just follow the simple Password reset Wizard as seen below, by selecting the pen drive from a list of drives it will show you. Note: If you have not inserted a Pen Drive before launching the utility, it will not work and will give an error. If the pen drive is in place, you will see Wizard something like the images below. It will also ask for your current password to create a password reset pen drive.
Step 3. Now you simple need to keep this drive at a safe place. You can use this in case you forget your Windows 7 Password sometime in future, just click forgotten password on the login screen and choose the option to Reset Password after inserting this pen drive into any of the working USB ports of your computer.
NOTE: Windows will honor only the most recent Password reset disk that you have created, so in case you happen to create more than one disk, only the one which is latest will work, all other old password reset disk will not be able to reset the Windows 7 Password.
If you have not created a reset disk and have forgotten your password, you can still reset the password using some utilities like Windows Password Recovery Tool. But these processes may cost you little money if you need to buy a software to do that. So to avoid any inconvenience later, we recommend that you create a password reset disk.
