World Moving Towards 64-Bit

• As of 2009, most new applications and hardware are designed to take advantage of 64-bit architecture, according to OS News. The Mac and Linux operating systems have already moved to 64-bit environments that can run any 32-bit application, and Windows 64-bit operating systems support most 32-bit programs.
  
  

For Legacy Devices, No

• Windows cannot run any 32-bit hardware in a 64-bit environment, according to Microsoft. In addition, some 32-bit programs, such as security software, have trouble operating in a 64-bit environment. If you run a lot of 32-bit hardware, it might be better to just stick with a 32-bit system or else you will have to purchase all new devices.
  
  

Bottom Line

• If you are purchasing a new computer system, you should move to 64-bit if you want to use the latest hardware and software. If you have a 32-bit operating system, consider that Windows will not let you upgrade to a 64-bit operating system and you may have issues running your applications and devices.
