# of Supported processors in Windows

Windows Version
Maximum Physical Processor Limit Maximum Logical Processor Limit
Windows XP Home Edition 1 2
Windows XP Professional 2 4
Windows Server 2003, Standard Edition
4 8 Windows Server 2003, Enterprise Edition
8 16
Windows Server 2003, Datacenter Edition
32 32


I looked long for this info and thought I'd share it Re: Windows software version and # of supported physical vs. logical processors. That is HT or Dual-Core.

HT and Dual-core = 1 physical processor as recognized by windows.

For instance XP Home = license for one physical CPU and 2 logical (that is one HT cpu or one dual-core CPU)

XP Pro = 2 physical 4 logical

Server = 4 to 32 depending on version.

Hope this helps somebody with their set-ups.
