No. It is an ARM device, not x86, and currently only x86 versions of Windows exist. See the FAQ.
Windows Embedded OSes (such as Windows Mobile) and Windows Phone 7 support ARM. Getting them to run on the RPi, on the other hand, would probably cost a lot of money. Its probably not worth it.
To implement a version of a Windows Embedded OS, you generally have to be working at the OEM level, either a manufacturer or hardware or a licencee for a particular platform. The fees to Microsoft for the SDK are priced at that level and you need a comprehensive Microsoft toolchain to implement it.
I think the phrase is "Does Not Happen!!!"
If you really want the feel of a Microsoft OS at this level, have a look on eBay for Disgo 3000 or Allfine netbooks. Disregarding processor speed, memory availability and rubbish IO facilities, thelack of updates, the inflexibility of the OS, the lack of control and inability to run any programming languages will mwke your brain squeak!
