You can install/run Windows on the SSD with some Thunderbolt enclosures. I have had good success with the Seagate GoFlex Thunderbolt interface using the 256GB Samsung 840 Pro. I had no success with a LaCie "Little Big Disk" (single disk only) and the Pegasus J4, neither of which claimed to be Windows compatible.
I have not tried using USB enclosures.
There are several threads here which you can search for discussing this in more detail.
