    Windows 10 and Intel Pentium 4 550 @ 3.40 GHz?

    I'm receiving the message "The CPU isn't supported" in the "Get Windows 10" app, against this older CPU (Pentium 4 550 running at 3.40 GHz).

    3.40 GHz is greater than the 1 GHz listed in the system requirements.

    Does Windows 10 have a thing against Hyper-Threading, or require Virtualization tech from Intel CPUs? Are Pentium 4s not supported at all?

    Has anyone gone ahead and run the upgrade anyway on this type of CPU?

    Win 10 Pro upgrade from 8.1 Pro stops at 25% every time.

    Upgrade to 25%, shows in the circle (84% files copied), takes less than 6 min. The PC seems to be running at full speed from here on, but after 9 hours nothing has changed. Several attempts gives the same result. When I turn of and on the pc (cold start),
    it goes back to Win 8.1 Error code C1900101-20004. (Intel Core i5 CPU, 3,4 Ghz.)

    Any suggestions from anyone how to solve this problem?

    Hi. Could you provide us with your computer's specifications. If you're not familiar with how to do this go to piriform.com and download Speccy.

    As you can se on the pic to the right (CPU-Z) I have a core i7 4790K running at 4,5Ghz, 16 Gbyte ram, ASUS Maximus Ranger VII mobo, Samsung 840EVO SSD. Do you need to know more?

    Read some threads where this happened in Windows 8.1 and flashing the BIOS fixed a few of them. You can check to see if there is a BIOS update for you system at the manufacturers web site.

    No new BIOS for my mobo. But I disabled "Intel Speed Step" and "Intel Turbo Mode" in BIOS under "CPU settings", and then it installed Can't upgrade from 8.1 to 10 - CPU less than 1 GHZ :)

    Seems like "Intel Speed Step" is set too aggressive and installation didn't manage to load it up enough to jump over 1 GHz.

    I don't think that is the case. If you look at the picture in #0 you can see, that the CPU is running ca 4500MHZ at the time. I ran Intel Extreme Tuning CPU Stress Test at the same time as running the setup.exe from Windows 10, and allthough the CPU-speed was ca 4500MHZ win10 claim the CPUspeed to be less than 1 Ghz, as shown in the picture.

    I think MS has to look into this install procedure again ...

    I believe MS recommends removing any overclocking before install one of their OSes. Put it back once done.
