No doubt Windows 7 themes are more beautiful and gorgeous than the themes of XP. Especially Windows 7 default, Bluewater, Avatar, EA Sports are really awesome collections for the Windows 7 users. If you are running on Windows7 then no issue, but the XP users might feel the crisis of such an exclusive theme.

XP users can’t install these themes because the theme file extension “.themepack” is not supported by XP. So if you can change the extension to the XP supported extension “.CAB”, you have all done.

First if you have any Windows 7 theme, open it in XP and look the file extension is .themepack that is absolutely unrecognized to XP. You can download some awesome Windows 7 themes from Microsoft site.

Now to change the extension, right click on the file and set the extension as .CAB, then click on “OK”. Now it will get recognized by your installed XP. Extract the .CAB file and double click on the .theme file to start to install. Activate the installed themes from “Properties” option.

Sometimes it may create problems during the extraction, then download and install WinRAR in your PC. Now the .CAB file should look like a RAR archive. So you can easily do the job by extracting it.

Once after extracting, you can further use the images as your desktop background as well.
