Now that Windows 7 RTM has been distributed to Microsoft Software Assurance customers, I have legally installed it on my work desktop. I used to run Windows Server 2003, so the Windows 7 eye candy and more desktop-oriented features are a nice change. However one thing I missed is the ability to have multiple RDP connections to my PC. Fortunately, ShadyMG over at Missing Remote has got it all figured out:

Update: It seems there is a more refined version of this patch, which also works to enable RDP server on the Home Premium version. http://thegreenbutton.com/forums/t/79427.aspx
