That's a 1997, 266 MHz Pentium II running Windows 7 Ultimate. Yes, it probably is quite slow - but it will run - and run with 96 MB of RAM at that.
Point taken. I guess I should have more accurately phrased my comment as "Windows 7 won't run worth a crap on a Pentium-II" rather than "Windows 7 won't run on a Pentium-II" (the latter implies "at all").
I have found that Microsoft is generally very cautious about their [minimum] System Requirements, which is where the 1GHz CPU "requirement" comes from.
Speaking of "it probably is quite slow", back in 1999 I ran Windows 95 on a 1988-vintage 30MHz 486 with 8MB of RAM. It took ages to do anything, and you could only load one application at a time. It was nearly f**king useless, practically, but it proved the same point.
