In short: no. Never. To port something you'd need the sourcecode, something I doubt Microsoft is willing to give up.
There is no port of any version of Windows to the PSP. People have been able to emulate Windows 95, but very very slowly and in a way that makes it mostly unusable. The DS has much more limited resources than the PSP so even this would not be possible. There's a port of a DOS emulator to the DS that runs incredibly slowly, and that's about as far as you're going to get.
WinDS looks somewhat similar to Windows, and Woopsi looks like an Amiga computer, but these aren't ports at all.
