    Default Cannot install Windows 10 on a NX supported desktop

    I have a desktop with an Intel Core2 Quadcore Q9300(32bits) I have tried to install Windoes 10 ,but I get a error message"Your CPU dont support NX"
    According to the Intel s specefication The Q9300 supports NX.
    I cheched it with Coreinfo: NX,PAE and SS2 supported.
    I checked is again with CPUID-CPU-Z : it says Intructions: MMX,SSe,SSE2,SSE3,SSE4,EM64T,VTX.
    I have also enable EDB(Execute Disabled Bit) in my BIOS
    Any suggestions??????

    OK here is what I found. The Windows 10 app compatibility test dont look at de CPU specs. It looks at reponse of some software. There are two barriers 1 is the nx setting in your BIOS the other one I call it the DEVIL is DEP (Data Execution Prevention). This is the one that made a that the compatility test said "Your CPU dont support NX) In mine case it was disabled and I could not change it(it was grey).
    I used the instructions to enable my setting with a coommand line. Impotant is to login as Administrator I tried to post some URL with those instructions but I was not allowed . (got an error massage)so you have to look for them yoürself. "Hpw to enable DEP

    I think a lot of user had the same problem as I had and did not check their CPU. used SiSoft Sandra to check my CPU specs Windows 10 is installed on my desktop and working very good

    I hope this information has been usefull

    Kind Regards

    I found that if you go into Computer->Properties->Advanced system settings->Performance Options->Data Execution Prevention and make sure "Turn on DEP for all programs and services except those I select:" is selected, the NX message does not appear. This is likely because Microsoft's test of data execution is not a "essential Windows program and service".
