Guys i have DJ Pro on Ipad do i need to buy it again for windows?
Yes. Djay Pro for iPad is not even half the cost of the Windows version which should be the first red flag 
Not sure if it works for Windows but the FX pack expansion IS interchangeable however… I think at least.
I do know I only paid once and I have it for Djay 2 (iOS) Djay Pro (iOS) as well as Djay Pro (Mac).
