Windows 10: Simple hardware (CPU) question:

Hate to burst your bubble but that CPU is a socket 775 CPU, not a 478.

 

Eh, Intel says they shipped that CPU in both socket 478 and 775 sockets.
Pics of the processors for sale show some are 478, some are 775.

Anyway, I had a 775 pin Prescott in a Dell 5150 that I updated to Win-10. I ran into a problem was that although the processor actually HAD the NX and 64bit commands, it didn't report them to the Win-10 installation program, so it would install the 32bit version of Win10, but not the 64bit version.

Probably not an issue for the OP, I assume they just want to get the 32bit version of Win10 loaded.

 

Hate to burst your bubble but that CPU is a socket 775 CPU, not a 478. Hey, good question, actually, now that I think about it, same processor in different sockets....

Looks like the OP might have an even better answer. Yes, there are P4 socket 478 CPU that will run Windows 10.
But they're scarce because they originally cost $1,000, and they might not work with your specific computer's bus and cache setup.

Appears there were actually a few Pentium 4 extreme chips made for 478 sockets!

Yikes big problem is the $70 - $180 price tag for a P4EE used processor!
