User Account Control, Mandatory Integrity Control and the execution of software as non-administratior.

• It creates a secure desktop that you cant access/modify from your code. (The secure desktop can be disabled with group policies. You would still see when your code requires higher privileges, but it wont lock up all screen with a secure desktop.)
• Automatic redirects when writing to system-wide stuff (Program Files, HKLM) to a user-specific location. (Somewhere under %AppData%\Local\VirtualStore.)
• Software marked as low integrity can only write to folders marked with low integrity.

Uhm, between XP and Windows 7 - the whole model changed. Depening on what you're developing (device drivers) you may face an entirly new system with an event based kernel model. Dunno... the question is very general ;).

If you develop Windows services, you should know that Windows services can no longer interact with the desktop starting with Vista. To communicate with a Windows service in Vista (and presumably Windows 7), you will need to use some sort of IPC, e.g., sockets, pipes, etc. If you've been holding off on learning Windows Communication Foundation (WCF), now would be a good time to do so since WCF can bridge this gap.
