Let me say that through a student scheme (Dreamspark) that I came across recently, I am able to get the key and am downloading the Windows Server 2008 R2 Standard X64. This is not an iso but an img file of 2.8GB. I am presently using win 7 enter x64 and also win 7 ult 64. My query is: 1. is it somewhat inferior or different to enter or ult. (no point in installing it then). 2. is it true that some programs are not compatible with server r2 std. 3. how do I install from an img file (is it like an iso where it is burnt to dvd and then installed). 4. finally, is the student key activation in perpetuity (as in like reinstall with same key) or does it expire on reinstall/after a certain time.
