Here are the Steps to Unlock those Hidden Themes:
- Firstly Click on Start and Open Computer.
- Now Copy and Paste the below code in the Address Bar (Do not try to navigate to it as folder named MCT is Hidden so you will not find it.)
Now open all the folders one by one. For example open MCT-AU and now Open Folder named Theme and finally Double Click on the File in it. Now Repeat the same for all the Folders.
Now when you Right Click on the Desktop and then Click Personalize then you will also see a New Theme which you can now use.
