How to factory reset windows 10 without password to new owner?

Using diskpart from Recovery Mode is a powerful built-in way to factory reset windows 10 without password, but it erases everything on the target drive instantly.

It allows you to completely wipe the Windows drive and reset the partition style, but using this feature requires entering Recovery Mode and using command-line tools.

First, boot into Recovery Mode by powering off the laptop three times during startup. Navigate to Troubleshoot → Advanced Options → Command Prompt.

Type the following commands one by one:

diskpart
list disk
select disk 0  (or your Windows drive number)
clean
convert gpt
exit

Then, install Windows from a bootable USB drive.

This method cannot be used to factory reset windows 10 without password while keeping your data, so it is only suitable for users who are ready to erase all data on the device.

If you don’t want to use third-party software, you can try this method. This is a drastic measure, so you should think it through carefully.
