2. Now right-click on the text file and click the “Rename” option to make your script for an activation key
3. Change the name of the file to “activator.cmd”
4. If you can’t change the file extension from .txt to .cmd, make sure you have enabled this setting in your Windows file browser using the following simple steps:-Click “View” from the top menu in your file browser
   -Now go to “File and folder options”
   -A new window will appear
   -You will see three tabs: General, View, and Search
   -Go to the second tab, “View”
   -Under Advanced Settings, you will see the option to check and un-check certain settings
   -Find “Hide extensions for known file types” and uncheck it to show extensions for all file types
   -Now you can easily change the extension of the file from .txt to .cmd when you rename it
5. Now right-click on the file (now a .cmd file) and choose “Run as administrator”
6. The file will run and you will see a window appear and then disappear on your desktop

Wait a few seconds and then restart your computer. When it comes back on, check the status of Windows. You will notice that you have an activated copy of the operating system without having to provide a Windows 8.1 product key.

This method may not work for everyone. It has a high success rate, but for some strange and unknown reason, it doesn’t always work.

If it doesn’t work, grab a Windows 8.1 product key from above to install the operating system. An activation key always works, as long as the key has not already been used by someone else.
