Using Reset This PC from the Windows Recovery environment is the most straightforward way to wipe a Lenovo laptop when you do not know the login password. This built-in option allows Windows to remove all user accounts, files, and installed programs, restoring the system to a clean state without requiring any credentials.

How to wipe a Lenovo laptop clean

1. Turn off the laptop completely.

2. Power it on and interrupt startup 2–3 times (hold the power button as Windows begins loading).

3. When Windows Recovery appears, select Troubleshoot.

4. Click Reset this PC.

5. Choose Remove everything.

6. Select Local reinstall or Cloud download.

7. Confirm and start the reset process.

This method fully erases personal data and removes the forgotten password, returning the laptop to a fresh Windows setup. It is quick, reliable, and ideal if the system can still access Windows Recovery, making it the first option to try before more advanced solutions.
