How to Check If your Processor is 32-bit or 64-bit in Windows?


So you have an old Windows XP or Vista computer and now how do you find if your processor is 64-bit capable?
There are different ways to find if your computer processor is 64-bit capable:

Method 1: 

Easy Method!

Go to Start -> Right click on Computer -> Click Properties. Click on Windows Experience Index.



Now click on View and Print detailed performance and system information.



Here you will be able to see the current system type, number of processor core and if it is 64-bit capable. Note: If you are already running 64-bit processor, it will show in the current system type and you will not see if it is 64-bit capable or not.

If you feel a bit geeky then you can use the following methods to find if your processor is 64-bit:

Method 2: 

Using Regedit

Go to Start -> Type regedit

Browse to HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0

From ProcessorNameString you will be able to see the name of your processor and from Identifier you will see the family of the processor and if it has 64 then it is 64-bit capable.



Method 3: 

Using MSINFO32

Go to Start -> Type msinfo32.exe

From the System Information page under System Type you will find as x64-based PC.



Method 4: 

Using CPUZ

CPUZ is a small utility which gives all information about your CPU (Processor), Cache, Mainboard, Memory, SPD etc.

Under Instructions from CPU tab, if you see EM64T (if its Intel) or AMD64 (if its AMD) then your processor is 64-bit capable.
