[citation][nom]thjbd[/nom]when i tried to install windows 8 RTM via usb, i got it "Your PC needs to restart.Please hold down the power button.Error Code: 0x0000005DParameters:0x030F02090x756E65470x49656E690x6C65746E"after googling i found that" To install Windows 8 , the processor (CPU) must support the following features: Physical Address Extension (PAE), NX, and SSE2."if my processor is pentium 4 1.6Ghz then why microsoft says that processor requirement is 1 Ghz? my processor doesn't support pae,nx.[/citation]
Microsoft probably didn't expect you to try using a new OS on a ten year old system that probably fails the system requirements for other reasons too anyway. Also, your CPU's clock frequency has nothing to do with it not working with Windows 8, so that it's clock frequency is high enough for the minimum specs is irrelevant. MS should add in that you can't use dinosaur hardware that doesn't support even old CPU features, but your frequency, what you used in your argument, had nothing to do with the issue.
Also, 1.6GHz on a P4 is similar to maybe a few hundred MHz on a more modern CPU. Yes, MS's system requirements are too vague, but to be fair, you are also using hardware that is very outdated. MS did say that Windows 8 would run on hardware that Windows 7 runs on and I find it difficult to believe that Windows 7 would perform even adequately on your system, assuming that it'd work.
