Windows 7 (64-bit) has 32-bit emulation layer and all applications that work in Windows 7 (32-bit) will work with 64-bit version also.

However, 32-bit drivers will not work.

Most will - some which make specific API calls may not (such as Anti Virus, Firewall, drivers or other "high level" software).
