As you know Microsoft released Consumer Preview for Windows 8 last week, Microsoft also released their first theme for Windows 8 CP users, you should know that this theme can’t be installed on Windows 7, however all Windows 7 themes will work in Windows 8 DP or CP.

Windows 8 Themes can’t be installed on Windows 7 PCs

If you’re interested to know the reason behind this, here is what Microsoft had to say : “all of our Windows 7 themes also work in Windows 8. But the reverse is not true. Themes created in the Windows 8 format will not work in Windows 7, because Windows 8 introduces a few new desktop personalization features that aren’t supported in Windows 7, and the file format is different.”

If we set aside new desktop personalization features in Windows 8, we learned that Windows 7 themepack file is of type “themepack” where Windows 8’s is of “desktopthemepack”. I’ve tried to change Windows 8 theme extension from “desktopthemepack” to “themepack” but didn’t succeeded in installing it.
