Can Atom N455 run Windows 7 Home Premium 64-bit

Yes, it can run Windows 7 Home Premium 64 bit, but I don't think the performance will be that great to be honest. Can you get one with Windows 7 Home Premium 32 bit? I am find really pointless having 64 bit with 2 GBs of RAM, since you won't see the key benefits unless you have 4 GBs or more. Also, since its a Netbook, the memory modules are likely soldered on the motherboard, meaning its not upgradable.

32 vs 64 bit

Is my PC running the 32-bit or 64-bit version of Windows?

Windows 7 64 bit comes in handy when you need to address at least 4 GBs or more of RAM. Windows 7 32 bit can utilize up to 3.2 GBs of RAM. Because the memory address space is much larger for 64 bit Windows, that means, you need twice as much memory than 32 bit Windows to accomplish some of the same task, but you are able to do so much more, you can have more applications open, do things like run an Antivirus scan in the background without it affecting your system performance. Windows 7 64 bit is more secure too, malicious code cannot easily infiltrate it, drivers are more reliable since they must be signed before they can work with 64 bit Windows 7.

As for compatibility, you will need 64 bit device drivers for any hardware devices you might have. Also, there is no 16 bit subsystem in Windows 7 64 bit, which means, your applications must be 32 bit only, not 16 bit installer or uninstallers.

Don't use the 64-Bit version, 2GB on an Atom will not hack it. Try the 32-Bit version instead as the mimumum requirement for memory is 1GB.
