HI, I've a desktop with windows 8 installed and activated by microsoft. While I attempt tu upgrade from windowsstore, I'm told that my processor is not compatible, that I need PAE, SSD2 and NX. If I run the upgrade assistant, I've the same result. If I run coreinfo, I find that PAE, SSD2 and NX are supported, which is correct since I was able to install windows 8. The test made by microsoft seems faulty. What can I do ? Where can I report for this problem ? Regards. Michel.
