I get valid responses on the systems I've checked - Server 2003 r2 (x86), Server 2008 r2 (x64), Windows 7 pro (x86), and Windows 7 Ultimate (x86). All of our x64 workstations were updated to Windows 8, so I can't validate the W7 64-bit platform. No SP on Win-8, so those systems return a blank value.
