Pre activity –

As the methods discussed ahead will erase data and make it irrecoverable, you should take a complete backup of your data on an external storage drive before employing them.

• Check web browsers for any plugins or websites on which you are logged in and sign out of them.
• Remember, some paid applications provide you with product keys. Note them down somewhere before signing out.

If you use your Microsoft account to sign into your laptop, you must log out of it and unlink the device. For the latter part, you will need to sign into your Microsoft account on another computer. Once inside, locate and click on the Devices tab and find the old laptop and remove it.

Once you are finished with the above tasks, proceed with the methods mentioned ahead to erase everything from your laptop.

Method 1: Perform Factory Reset

• Click on Recovery in the left pane.
• Go to the Reset this PC section and click on Get Started.

• Click on Confirm.

• Click on Next.

• Carefully go through all the changes that will be made upon resetting the PC on the final screen.

The process will take some time to clean the drives off the data, settings, and software and reinstall a fresh copy of Windows on the computer. After this, your computer will restart and you will see the Windows setup screen. Follow the instruction to set it up like a brand-new PC.

Once the system is reset, it will return to its factory-like state with no additional applications. All the user data will be removed along with the third-party applications.
