    Make sure you follow step 2 carefully where you need to run the command prompt as administrator, it can make the script to not work if not run as administrator.

  5. For those who can’t get this to work and are too lazy to search for the file on their computer….
    C:\Windows\System32 – Open this up.
    Scroll down to slmgr.vbs Now, mine had “.watremover” after the file name.
    Remove that an the command now works in comand prompt..
