I have Windows 8 CP 32-bit installed on a Dell GX260 with a P4, and Win + 8 works on it, but I also have Windows 8 RP 64-bit installed on a Dell GX620 with a Pentium D, and Win + 8 does not work on that system.

Has anyone else tried Win + X on Windows 8 RP? My installation of Windows 8 RP could be broken, but Microsoft is busy ripping all the good stuff out, and Win + X may not work anymore in RP.
