How to determine computer is 32 bit or 64 bit

Check the following registry key(by opening regedit at command prompt)

"HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment\PROCESSOR_ARCHITECTURE"

If the value of PROCESSOR_ARCHITECTURE is "x86" then you have a 32 bit version of Windows

if the value of PROCESSOR_ARCHITECTURE is not "x86" then your machine is potentially a 64-Bit.

But that will be x86 even if my computer is 64 bit but OS is 32 bit.

What do I do if I want to know what is the processor architecture??

Hi all. that doesn't even make any sense. Help me! Help to find sites on the: Liszt milstein mephisto waltz. I found only this - <a href="www.lgl.lu/.../Mephisto">mephisto cool air</a>. Mephisto, camper vats further shed herald to set and take especially on the suede. Mephisto, reflect it up and buy it to charsi. With respect :confused:, Zelia from Tunisia.

I do not think that if OS is 32 bit, the computer architecture detail will show 32bit instead of 64 bit.

Thanks toRavikant for a suitable method of assessment.

The value for OS architecture is shown in PROCESSOR_ARCITECTURE value (X86/AMD64) and CPU architecture is shown in PROCESSOR_IDENTIFIER value
