[SOLVED] In theory, what is the slowest CPU that can run Windows 10?

[techflame700]

Title says it all. Also, for the record, I am not actually going to attempt to use / build a machine with whatever CPU it is (obviously). This is just a question I can’t seem to get out of my head for some reason. The CPU requirements are so vague I don’t even know where to start.

Here’s a link to the system requirements Microsoft has posted: https://www.microsoft.com/en-us/windows/windows-10-specifications

Thanks!

Later Pentium 4 CPUs are the oldest from Intel that have all of the applicable features/instructions to be able to run Windows 10.

Theoretically a Celeron D or something would also work since they are just worse Pentium 4 CPUs. Maybe an atom of the same time.

The clockspeed doesn't really matter for it being able to just start Windows, but what is necessary is the proper CPU features, things like PAE or some version of SSE iirc.

Discussion - What's the oldest and/or cheesiest system you have Win 10 installed on?

Mine is a 2009 era Toshiba Satellite L305-S5955 Celeron 900, 2.2GHz, 2GB RAM, 250GB HDD. The only upgrade from stock was a warranty replacement of the original 160GB HDD to the current 250GB. Currently v1903, Build 18362.295 https://www.cnet.com/products/toshiba-satellite-l305-s5955/specs/...

There are 'versions' that have been installed on phones which by nature have very low-power processors and fairly 'slow' by desktop standards:

How to Upgrade Your Windows Phone to Windows 10 Now

Microsoft is technically selling two phones with Windows 10 built-in, but it hasn't released the update for older phones just yet.

Then Microsoft also has this information for us:

I also think it's got as much to do with the peripheral hardware as anything else. Are there Win10 drivers for ST-412 or ESDI hard drive interfaces?
