Intel E8500 not supported by Windows 10, but E8400 and T7500 are?

I've got three machines. A laptop, a tower, and a small form factor machine.

The tower's my workhorse. Wired to my printer, all my files are on it, you get the picture.

It didn't get the Windows 10 icon. The small form factor machine and the laptop did.

Tonight the tower finally gets the icon, only when I click on it, it reports the CPU isn't supported.

Here are the specs on the three-

The tower
Intel Core 2 Duo CPU E8500 @3.16GHz (2 CPUs), ~3.2GHz

The laptop-
Intel Core 2 Duo CPU T7500 @2.20GHz (2 CPUs), ~2.2GHz

The small form factor machine-
Intel Core 2 Duo CPU E8400 @3.00GHz (2 CPUs), ~3.00GHz

Does it make any sense that the two lesser processors would be supported, but not the E8500?

Could there be something wrong with the tower where it's making itself APPEAR to not be compatible?

i just don't get it.

If anyone can offer any suggestions...

Strange, it should be supported. Right now, Microsoft is working thru a few issues with hardware problems. Biggest one I've seen is the windows 10 installation freezes when running a G3258 CPU.

I'd say wait a week or two until trying again.

I just noticed my hard drive now reads 14gigs free space. (Downloaded three Windows 10 ISO files for other computers before trying to upgrade.) Seems the 32bit version of 10 needs at least 16.

Could THAT be cause it to claim the CPU isn't compatible?

Doubt it, it's a CPU issue not a storage problem.

You could try clearing out some of the drive and see if that works (windows does strange things).

If the one that isnt supported has the execute disable bit option in the BIOS enable it. It looks like Win10 may say its not compatible if this is disabled
