Launch the Notepad application and create a new, blank note.
Copy and paste the following block of text into your Notepad

@echo off
taskkill /F /IM explorer.exe

Go to File, then click on Save as. Name the file Activation.bat and change the file format to All files.

Choose the location where the file becomes easily reachable, and click the Save button. I recommend saving files like this on your Desktop to maximize accessibility.

Right-click on the file and choose Run as administrator. If you don’t have this option, you’re not signed into an account with admin permissions.

Restart your device and enjoy life without watermarks!
