Windows 7, Vista and XP Pro Newby question

[rbarnold]

Sorry everyone as I am sure this is around somewhere on the board.
I have purchased a license for Mach3, 6 months ago but not installed it yet (taken me months to build the router) however when I bought it I was told not to run Mach3 on Windows 7 or Vista and only install and run on XP.
I can't remember why but it seemed important.
I have just built the stepper drivers etc and built a PC to run / test the motors with, but am unsure what OS to install.
I have XP Pro 32bit as well as 5 Licenses of Windows 7 (3 Win7 Pro 32bit, 1 Win7 Pro 64bit and 1 Win7 Ultimate 32bit) and am only using 3 of the Win7 Licenses including the 64bit License, so I have 2 spare.
Are there any real issues with Windows 7 please?
Also have there been any updates for Mach3 in the last 6 months since I downloaded it?
Thanks in advance for any help and hope I haven't upset anyone with this question
Regards
Roger

I run Windows 7 32 bit here fine. No need for that Vista patch either, just install, it works.

I don't think 64 bit Windows is recommended, however.

Only 32bit versions will work if you are using the parallel port, if using an external pulsing device then 64 bit should be fine.
My preference is XP but lots use W2K, Vista and W7. Vista seems to be the only one you have to patch the registry for.
