Most likely your Ubuntu uses PAE, and Windows does not. NT kernel certainly supports PAE, but likely MS has disabled it in client systems for some reason.

Nope. They can't actually disable it since the NX bit requires that PAE be enabled.

The limitation comes from licensing and tiering, and is handled in the kernel independently from PAE.
