I would like to build a new computer (it's been 7 years since the last one). Does Windows 10 support more than one CPU socket?

  • Yes. As an example, will Windows 10 support, 2 E5-2699 Xeon processors?

  • I'm not sure if this information is documented anywhere yet. Perhaps ask on the Microsoft forums, this user was able to get the information for Windows 7: answers.microsoft.com/en-us/windows/forum/windows_7-hardware/… It will probably depend on the edition of Windows as well: Home, Pro, Enterprise

  • 4
    One socket for Windows 10 Home. Two sockets for Windows 10 Pro, Enterprise, and Education. Any number of cores is supported.

  • I see no reason Microsoft would change this limit that has been around for years. It use to be printed on the old COA stickers in the XP days

Depends on windows variant and architecture. Win10 Pro x64 supports 2 sockets, 256 logical cores and up to 512GB RAM

For more sockets you need to get a "server" os

There's an answer from ms insider here

from https://www.microsoft.com/en-us/microsoft-365/blog/2017/12/15/windows-10-pro-workstations-power-advanced-workloads/

I was looking for the answer to the same question yet find the answer right here. Btw, I noticed that windows 10 enterprise build 10240 recognized only 2 CPU sockets. But it does recognize 4 CPU sockets after I update it to build 1903.
