How to uninstall or delete a theme pack in Windows 7 and Windows Vista
This article applies to theme packs deletion only, and not the visual style based themes. Theme packs that I am referring here ends with .themepack extension. Since each themepack consists of several wallpapers that occupy a lot of hard disk space, it is better to get rid of those unused themes that you have accumulated over a period of time. Unfortunately, Windows doesn’t give a easier way to delete the theme packs directly from personalization gallery.
Manage Themes On Windows 7 and Windows Vista
You can find all the themes installed in Windows 7 and Windows Vista in the Personalization gallery. Right-click on empty desktop and select “Personalize”.
All the themes on your PC is listed here in the Personalization Gallery including Aero themes, basic themes, and high contrast themes.
It would have been great in Microsoft had given some way to manage the themes here. Even being a administrator of your PC, Windows doesn’t give a straight away option to delete these themes. “Delete” key doesn’t work and neither the right-click context options work here. You can only add new themes by clicking on the link “Get more themes online”. So where are these themes located on your hard disk? Make sure you are logged into Windows with Administrator rights because you need to go into the system folder to manage these themes.
1. Explore the Windows installation partition, usually C: drive in most of cases.
2. Go to C:\Windows\Resources. You will see two folders here including “Ease of Access Themes” and “Themes”.
3. “Ease of Access Themes” will have the default high contrast based themes that can’t be deleted.
4. “Themes” folder will have all the downloaded themes. You can delete them.
5. Note that you can’t delete the default themes that was shipped with Windows.
