This is done by just double-clicking or double-tapping the file; another program or install utility isn't necessary for the files to run. The newer .DESKTHEMEPACK files are not backward-compatible with Windows 7, which means that while .THEMEPACK files can open in all four versions of Windows, only Windows 11, 10, and 8 can open .DESKTHEMEPACK files.

Windows uses the CAB format to store the contents of THEMEPACK files, which means they can also be opened with any popular compression/decompression program, the free 7-Zip tool being one example. This won't apply or run anything inside the THEMEPACK file, but it will extract the wallpaper images and other components that make up that theme. If you have a THEME file that isn't a Windows theme, it may instead be a Comodo theme file used with Comodo Internet Security and Comodo Antivirus, or a GTK theme index file used in GNOME.

If you find that an application on your PC tries to open the file but it's the wrong application or you'd rather have another installed program open it, see How to Change File Associations in Windows for our guide on making that change.
How to Convert a THEMEPACK File
If you want to use a .THEMEPACK file in Windows 8 or newer, there's no reason to convert it because it's already compatible with those versions of Windows just like it is with Windows 7. However, you may want to convert a .THEMEPACK file to a .THEME file.

You can do that with the free Win7 Theme Converter. After you load the file into that program, place a check on Theme output type and then select Convert. If you want to use the newer .DESKTHEMEPACK files in Windows 7, the easiest thing to do, instead of converting the .DESKTHEMEPACK to a .THEMEPACK file, is to open the .DESKTHEMEPACK file in Windows 7 with the free Deskthemepack Installer tool.

The background images in a .DESKTHEMEPACK file are stored in the DesktopBackground folder. You can use those images when you change your Windows wallpaper to have them apply to Windows 7. If you need to convert the wallpaper images or audio files into a different file format, use a free file converter.

Still Can' t Open It
THEMEPACK is an unusually long file extension (most are just a few characters), but you might still mix it up with similar looking files. When this happens, you more often than not have to take an entirely different approach at opening the file, and this is especially true in the case of this file format. PACK files, for example, might at first appear to be related in some way to Windows theme files.

More on Windows Themes
Windows also stores themes with the THEME file extension, but those are just plain text files. They describe colors and styles that the theme should have, but plain text files can't hold images and sounds.

You can only export custom themes. Right-click a blank area of the desktop, select Personalize, and go to Themes. Right-click the theme you want to transfer, select Save theme for sharing, enter a name for the file, and save the theme to your desktop. Transfer the file to the other PC and then open it to install it there.
