I had a few other ideas:

GetKeyboardLayout -- umm, I get 08090809
GetUserDefaultLangID -- "" (or), I get 02000809

GteLogicalDrives/GetDriveType=DRIVE_FIXED, eg:
	C: only: #4, C: & D: : #C, C:, D:, &E: #1C

GlobalMemoryStatus.dwTotalPhys	-- **GOOD**, I think

QueryPerformanceFrequency		-- **GOOD**, I think

The one I failed big time on was DeviceIoControl, with either 
"\\\\.\\C:" or "\\\\.\\PHYSICALDRIVE2"; I just could not get a handle 
from CreateFile (with the intent of getting TracksPerCylinder/ 
SectorsPerTrack/  BytesPerSector). If you can get that to work I would
like a copy (I can email my failed attempt if you like, and working 
code for phys.mem/pFreq).

I also thought about ComputerName, TimeZone, and GetVersion but 
quickly realised they should not be used as same PC could have 
multiple OS installed / be jet-setted around the world / need OS
re-install, etc.

The concept of say 3/5 matches means same machine, which the 
above link extols, is a pretty neat I think, thanks for that.
