Terminal Server Patch
The beta 2055 release of XP PRO SP2 let you run two or more sessions 
(one local console and one or more remote desktop) concurrently. 
But this functionality was removed in the Final release. 
This patch will enable two or more concurrent sessions in 
Windows XP PRO Service Pack 2 (SP2) or later if you have 
FAST USER SWITCHING enabled, and your windows is NOT in a domain.

Uninstaller is also included and can be found at windows Control Panel -> Add or Remove Programs.
