My advice! STAY AWAY FROM WINDOWS HOSTING AND ESPECIALLY PLESK! Windows is nowhere near as stable or fast as linux.
Windows is plagued with memory leaks.
Windows will break frequently.
Plesk is database driven eye candy.
Please puts a very high demand on your database.
Plesk doesn't sign out users properly and will lock down.

If you don't have to have windows stay away from it!

Bill can kiss my rear!
