Uxtheme Multi-patcher allows you to use any 3rd party msstyle theme on Windows XP/SP1/SP2 or Windows Server 2003 (with Themes enabled) by patching the uxtheme.dll (dynamic link library).
What's New in This Release:

• Added 64-bit support (not 100% work)
• Added few delay (about 2.5 seconds) in some tasks to make it done before doing next task (which I assume it solve some issues)
• Added Windows Server 2003 SP1 support
• Added stopping Themes service during patching for more success chance
