Windows 10: PrefetchW requirement for Windows 10 64 bit.

Hello. I have tried to upgrade to Windows 10 64 bit several times but my processor does not support PrefetchW. Supposedly 64 bit Windows 10 runs on Pentium 4s and I have an admittedly ancient Pentium D. It runs Windows 7 64 bit Ultimate just fine but refuses to install Windows 8.1 or Windows 10 64 bit editions. If I install a 64 bit edition using a different computer and then transfer the hard drive into the Pentium D machine it locks itself into Startup Repair and reboot cycle. I found out about the PrefetchW issue when using the Microsoft media creation tool. Ii don't know. What to do at this point since a hardware upgrade is not an option for the foreseeable future.

:)

 

Will without prefetchw, windows 10 can be install on 64 bit pc?

Actually, when I update bios, my 32 bit pc showing 64 bit pc. I have a window 10 of 32 bit after bios update I try to install Windows 10 64 bit but it shows that prefetchw is not there. Then how i install windows 10 64 bit to my pc or continue with Windows
10 32 bit with 64 bit pc.

Installing 32-bit Free Win 10 upgrade On a 64-bit Win 7

I'm going through all Computers in my house putting the free upgrade on them. I came to one of my computers. It's running Windows 7 SP1 64-bit. I'm installing the Windows 10 and I get a error saying "Processor doesn't support PrefetchW"

Okay, after all the 64-bit requires a processor that supports it

• To install a 64-bit OS on a 64-bit PC, your processor needs to support CMPXCHG16b,
  PrefetchW, and LAHF/SAHF.

So I'll do 32-bit Windows 10. However the setup will not run. It wan'ts me to do 64-bit.

I've looked in the registry and cannot find anyway to trick the computer into thinking it's a 32-bit.

I created a USB drive of Windows 10 32-bit from another computer, however, now it asks for a product key. It will not take my Windows 7 SP1 Key.
