How to check whether my hardware is 64-bit capable in Windows?

Install and run Securable, it will tell you. If you get the 64 max bit length, then yes your processor supports it.

Answer 2

From http://windows.microsoft.com/en-us/windows7/32-bit-and-64-bit-Windows-frequently-asked-questions paraphrased for Vista:

1. Open Performance Information and Tools: Clicking the Start button and then click Control Panel. In the search box, type Performance Information and Tools, and then, in the list of results, click Performance Information and Tools
2. Click View and print details
3. In the System section, you can see whether or not you can run a 64-bit version of Windows under 64-bit capable

Answer 3

Install CPU-Z, run and check out results. If you are unsure, post results (screenshot) to your question. There is no good way in Windows for determining that, except if your Windows is already 64bit. Check out for example this question.

Answer 4

Another method to find out if your processor supports 32 or 64-bit:

1. Click on the Start menu
2. Click Run (or type run on Windows Vista/7 and press Enter)
3. Type regedit and press OK
4. Navigate to HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\SYSTEM\CENTERALPROCESSOR\0

Look at the Identifier, it should say contain "Intel64" or "Intel32".
