I just installed 7 on my laptop last night. I will install CFS2 under it after Church today and get back in here tonight and let you all know what my experiences with it are.
I am going from 32bit to 64bit, so there might be some issues that I am unaware of right now. However, I noticed in the install last night that WIndows 7 has a conflict resolution section in it for programs that worked under previous versions. I will see if that is needed.
So far, Windows 7 appears to be a better OS than Vista, my opinion is still unformed with comparison to XP.
BTW, I dual boot, or more accurately, multi boot. I have XP, Vista and Windows 7 on the laptop.
I have XP and Vista on the PC and will be moving to probably a dual boot XP and 7 on the big PC later on.
