If you've forgotten your computer password, you can try the following steps to reset it:
Use a password hint: You may have already set a password hint when you set your password. If so, try remembering the hint and see if it brings back your memory.
Use another account: If you have another account with administrator privileges, sign in with that account and reset the password for your locked account.
Use a password reset disk: If you previously created a password reset disk, insert the disk into your computer and follow the on-screen instructions to reset your password.
Use Command Prompt: If you have access to Command Prompt, you can reset your password by typing net user [username] *. Replace "[username]" with the name of the user account for which you want to reset the password, and then press Enter. Follow the on-screen instructions to create a new password.
Use a password reset tool: If none of the above works, you can use third-party password reset tools such as Ophcrack, PCUnlocker, PassMoz LabWin, etc. These tools can help you reset your password and regain access to your computer.
Resetting your password may result in you being unable to access any encrypted files or folders on your computer. Therefore, it is important to back up your data regularly and record your passwords in a safe place to avoid losing them in the future.
