I Cant Start the computer because I forgot my password on my old computer with Windows 7

Hi Buddy Soubra,

Thanks for reaching out here in the Microsoft Q&A. I can understand the inconvenience this issue has caused you. To help resolve this issue, please follow the steps outlined below: 

Method 1: Reset Via Another Admin Account

This method requires knowing the password for another admin account.

• Log in to that account (in Safe Mode if needed, using F8).
• Go to Control Panel > User Accounts.
• Select your locked account and reset the password.

Method 2: Built-In Administrator Account

Windows 7 often has a default Administrator account that may not have password or might use a different one you remember.

1 - Restart the computer and boot into Safe Mode:

• Press F8 repeatedly as the computer starts (before the Windows logo appears).
• Select Safe Mode from the Advanced Boot Options menu.

2 - Look for an Administrator account on the login screen.

3 - Try logging in without a password or with any known passwords.

4 - If successful, go to Control Panel > User Accounts to reset your account’s password.

Method 3: Password Reset Disk

If you previously created a password reset disk, you can use it to reset your password.

• At the login screen, click Reset Password (appears after a failed login attempt).
• Insert the password reset disk (USB or floppy).
• Follow the wizard to create a new password.
