    8.1 upgrades says won't work with Pentium 4 Prescott 630


    I went to update my father's old PC to 8.1 and I get the message that his CPU is not supported. That you need the combination of SSE2+NX+PAE.

    He has a Intel Pentium 4 Prescott 630 3GHz. I looked it up and it should qualify for the upgrade. I ran CPUID and it says it has the SSE instructions (says MMX, SSE (1, 2, 3), EM64T).

    I'm pretty sure it supports PAE (how do I check that???).

    And in the BIOS, the Execute Disable Bit is turned ON (this is Intel's equivalent to NX?).

    Is there any way to bypass this check and install the OS?

    Hello dirtyvu,

    I was able to run my old p4 630 Prescott under Windows 8 Pro and it ran fine. So are you hinting that it worked on 8.0 and now is not upgradable to 8.1?

    Update: And where are you getting this no-go warning/caution from?

    Yes, the system has been running Windows 8 since the beginning. But the 8.1 update from the Windows Store won't go. Says the CPU doesn't meet the qualification.

    Hi there
    x-86 / x-64 -- are you downloading correct version

    Cheers

    I don't get a choice. I go to the Windows Store. Click on the tile to upgrade and bam, I get the message saying I can't upgrade. Windows 8 was the x64 version.

    Hi dirtyvu,

    Apparently, you are on the leading edge of (yet) another Win 8.1 discovery. So, are you trying to upgrade a Win8 installation that is Legacy or UEFI? If UEFI, do you currently have Secure Boot enabled?

    I'm pretty sure it supports PAE (how do I check that???).
    You can download "coreinfo" to confirm those features are supported. In my example below, I placed the coreinfo exe file directly in my system32 directory to make it easier to run so I would not have to construct a pathname to the exe file (I'm just lazy):

    Here are my results:

    Note that the * (asterik) indicates that feature is supported and the - (dash) indicates it is not. If interested, you can download coreinfo here:

    However, I think MS needs to publish a "what's new" list for 8.1 CPU requirements because something has obviously changed. Good luck.

    Well, it's an ancient computer. My car is younger than this computer. When I installed Windows 8, it was a clean installation (no upgrade) and I pretty much selected the default options.
