Se7en UxTheme Hexer

While many users don't mind the default look of their operating system, especially since they prefer focusing on functionality, others look for ways to customize every part of Windows and make it their own.

Force Windows to allow installing third-party themes

To be able to install software made by third-party developers, which focus on bringing a fresh look to Windows, you have to bypass some OS restrictions and enable third-party customization.
This can be done by using a simple and straightforward tool made to allow patching themes by other parties, such as Se7en UxTheme Hexer.

Enable theme patching in Windows 7

As the name of this utility says, it only works with Windows 7. In fact, we tested it on OS versions past Windows 7 to demonstrate that it has no impact.
It's not necessary to install Se7en UxTheme Hexer, since it's compressed into just one .exe. It can be copied anywhere on the computer and even stored on a thumb drive to be able to run it on any PC without setup and seamlessly enable UxTheme patch support.

Make the modifications and undo them if necessary

The interface is made from a single window that shows everything in plain sight.
A button is responsible for enabling the patch support ("Path Uxtheme") while another can be pressed for undoing all modifications and disabling patch support if you change your mind ("Restore").
Worth mentioning is that, if the UxTheme was already modified by another software application, then it's you have to click "Restore" before "Patch Uxtheme".

Create system restore points

Additional options are available in the "Program" menu, where you can create a system restore point in case Windows stability issues occur, restore backups, and reboot the system.
All things considered, Se7en UxTheme Hexer delivers a straightforward solution for enabling theme patching in Windows 7. Too bad that it doesn't work on newer OS versions.
