Question
Wednesday, July 29, 2015 5:12 PM
I originally posted this on the Preview forum but didn't get an appropriate answer so I am hoping I can get one here.
I received the Windows 10 icon on my laptop but I couldn't find the option to reserve my copy. Having tried the Check PC option, I got the notificaton that my CPU is not supported! Now, I know my laptop is slightly dated, but it is a HP pavillion DM4 laptop running an dual core i5 CPU which is supposed to be a supported processor. I have already installed the Technical Preview from an ISO image on this laptop and it seems to run just fine. So why does Windows update say Windows 10 will not run on my laptop?
One of the mods pointed me at another thread, that stated that sometimes the Windows 10 update app gives the wrong information. Unfortunately, this does not help as I still have no information as to why other than #'CPU is not supported' nor any other way of upgrading it.
By contrast, my desktop PC which runs an even older i3 processor is appearently supported.
So is there any detailed information on what the requirements are? My laptop definitely meets the basic requirements, i.e. 1gb RAM, 1Ghz CPU etc so what's the issue?

Hi,
I had the same issue, and couldnt find anything in the BIOS to enable the NX bit.
After lots of research, found I could by using BCDEDIT to turn on NX - it worked!
Brief guide:
Start CMD prompt as Administrator
BCDEDIT enter
shows you the current entries
to enable the NX bit always (which is what I did to pass the Windows 10 update check)
bcdedit /set nx alwayson
You'll get a "Command completed successfully" - then REBOOT and try to run your update - you can force an immediate update by downloading and running the MediaCreationTool.exe from https://www.microsoft.com/en-us/software-download/windows10

Can you post what exact CPU you have? If you can use a program like CPU-Z to identify it. The reason I ask is because I read recently how certain Intel CPUs have a known issue and wondered if it was one of those.

Believe it or not I've actually solved it!
I had a look in the BIOS and noticed that in the processor settings section that the Virtualization feature was disabled. I had no reason to enable it as I was not running any virtualisation software. Everything else was enabled. I enabled virtualisation and went back into Windows 7 and found that the 'CPU is not compatible' error was gone and the button to reserve a copy of Windows 10 had appeared!
I have now reserved my copy and thought I'd post this on here in case anyone else runs into this problem.
I hope this will now allow me to at least obtain a Windows 10 activation key so that I can install from the ISO which I downloaded today? I saw a suggestion on another forum that one could use the Windows 7 key from the retail packaging (I have retail copies of both Windows 7 Home Premium and Windows 7 Pro) but this did not work.

It is a dual core i5 processor, identified in Windows as Intel core i5 M450, running at 2.4Ghz.

Not sure what's going on here but after a couple of hours I had a look at the status of the reservation in the Windows 10 tool in the task bar, and it was again telling me that my laptop CPU is not compatible! A reboot later, the Windows 10 update tool icon had disappeared from my taskbar?
I decided to try the Media Creation Tool instead. To my relief it didn't stall or complain on the pre-install processes. A while later the Windows 10 upgrade was downloaded and then upgrade process began. It took perhaps between an hour or two for the process to complete, but the end result was that my Windows 7 installation was upgraded to Windows 10 sucessfully. I have yet to test it to any significant extent and therefore cannot yet confirm that everything works, but at least for now it would seem that Windows 10 will run on this laptop.

Thanks for sharing your detailed experience here. It would be very beneficial for other community members who have similar questions.
You can check the hardware vendor for the latest updates before performing the upgrade.

My recommendation is to run CoreInfo to verify support for PAE, NX, SSE2, CMPXCHG16b, PrefetchW and LAHF/SAHF.

Here's a post regarding the NX Bit and DEP

I had a particular issue but as it as last spring cannot recall exactly what steps I took. My HP Pavilion dm4 kept prompting me to download the free Windows 10 so I ran the compatibility test, both in Microsoft and HP. Both said the laptop was fine for Windows 10. I kept telling it to Remind Me Later and it finally downloaded it automatically. I did not refuse as had been intending to upgrade.
Windows 10 was fine for a week or so - a great OS - but then started glitching and finally BSOD. I had to purchase the Microsoft Assure for $149 + tax. Three days and 11 hours on phone later, I had to reinstall Windows 7. HP had stopped supporting this model, the very one it said was compatible with Windows 10! No more drivers to support the upgraded OS regardless of having said it was compatible. If I type my product number now, HP says Windows 7 is the only OS available for this model.
Am furious. Lost time and money. Can the manufacturer do this? Do I have any recourse?

Enabling Data Execution Prevention in the BIOS did the trick for me.
