How to Check if a Processor is 32 or 64bit

We usually look into big things and tend to forget how to do simple things. Well, this happens with almost everyone, me too! I got an email from a user asking me if his computer would install 64 bit operating system. So, I thought of writing this topic over here.

Before you get a 64 bit operating system you must make sure that your processor is 64bit. You can do so by having a look at My computer> Properties in Windows Xp, Vista and Windows 7. For Windows Vista and 7, here’s how you check it:

Go to Start menu> Right click on Computer> Properties

Under the head- system, click on Windows Experience Index

Under the score click on ‘View and print detailed performance and system information

You’ll get a detailed info regarding your computer. Under the head System, have a look at the system type and 64bit capable. The system type will state the type of operating system (32bit or 64bit) and if 64bit capable is ‘Yes’ then you can install any 64bit operating system. If it’s ‘No’ then unfortunately you can’t.

    So, what’s the way under XP? The Windows Experience Index isn’t an option for that OS.

  • Oopsy.. long time since I used Windows XP. I thought we could see in Properties 😛
    Well, you can use CPUz
    Under CPU tab> Instructions, if you see EM64T (if its Intel) or AMD64 (if its AMD) then your processor is 64-bit capable.

    Ran CPUz looked at CPU>Instructions gives the following: MMX,SSE,SSE2,SSE3
    Any other clues to find if 64bit capable?

  • Unfortunately, it isn’t
    Can you tell me the processr model plz

  • well this tells us about the operating system that wheter it is 64 bit or 32 bit not about processor
    I have installed both 32bit and 64bit windows vista on my pc and when i followed ur method it shows 32bit Operating system when 32bit vista was installed and 64bit when 64bit vista was installed
