StampThemes is a Windows utility that lets you mark an application as 'Windows XP Themes' compliant. By doing this, old applications which do not have the XP style will have the XP style!

They are some requirements for the application to look good when it is marked:
- The application must use the Windows Common Controls (most applications do use the Common Controls)
- The application must not have custom draw controls which are uncompatible with the XP style (some Controls may look ugly...)

StampThemes can also be used to remove the XP style from an application
