Let XP and Vista also use the Windows 7 theme package

a .themepack theme package to change the theme, no need to crack any system files. There is also a nice feature that allows users to match their own system theme and share it with other Windows 7 users.
This makes the users who are still stuck on the XP or Vista platform more uncomfortable, but really there is no way? Not necessarily! Although XP and Vista systems can not directly identify the theme pack for Windows 7, but we have Workaround.
First of all, you need to get a Windows 7 special .themepack theme package (Windows 7 theme package download), then change the theme package suffix name to rar and extract it to any directory. You will see something like this:

Windows 7 file content
Next depending on the system:
If you are using Vista and the Aero effect is already on, double click The .theme file in the folder, then go to the DesktopBackground folder and set the wallpaper inside to your current desktop background.
XP does not support Aero effects, then you can only use the wallpaper in the DesktopBackground folder as the background.
Windows 7 supports automatic wallpaper replacement, Vista and XP will not work, you need to use some third-party tools to achieve. If you only need basic timing changes, you can try this free tool: ScrollWall.

Software main interface
This program will be run automatically after installation. Click [Add] in the lower left corner to add a picture, then you can choose the default style of the wallpaper. [Default Style] is Stretch, centered. (Center) or Tile (Tile), this is the same as the system's own wallpaper options. Of course, you can also set a separate style for a piece of wall paper through the right area, suitable for individual special size wallpapers.
The Change Wallpaper on the lower right side is the key object. You can choose how many minutes (or hours and seconds) to change. You can also set it to change only after each system startup. Click [Apply] after finishing. Make the settings take effect.
Some theme packages may also include .wav system sound effects. Vista users will automatically import sound settings when double-clicking the .theme file. XP users will need to manually copy these files to the C:WindowsMedia directory.
Similarly, if there are files such as .scr (screen saver) and .cur (mouse pointer) in the unpacked archive, you need to manually replace it:
The screen saver file needs to be copied to C:WindowsSystem32, then To enable the screen saver;
copy the mouse pointer file to C:WindowsCursors, then enable the new pointer style in the mouse settings in the control panel.
Okay, after some hard work, the Windows 7 theme will be successfully ported to your current system, but the process is somewhat cumbersome. Who is letting us use Windows 7?
