Thanks to params for the heads up on this
A new build of Windows XP SP 2 has escaped - now v1194 and built on the 1st of April - (no April fool). This looks as though it is just an update to 1185 - still just patches and fixes. The rumour now is that SP2 will allow two concurrent RD sessions when using a second generation Smart Display - this will enable a smart display to be used without kicking the current user off of the system.
Check out the screenshots below.
Note: In the second screenshot WMP9 and Windows Messenger are pre-installed versions prior to installing this SP. So WMP9 hasn"t been updated and neither has Windows Messenger. This is just a hotfix build. We shouldn"t see any major changes or updates to the SP until it hits beta which will hopefully be sometime soon.
