Do I have a 32 bit or a 64 bit processor or operating system on my computer?

What is the difference between a 32 bit and 64 bit operating system

A 64 bit operating system is an operating system such as Windows XP or Windows Vista, that has been purposely developed for a computer with a 64 bit processor. You cannot use 64 bit software on a computer with a 32 bit processor but you can use 32 bit software with a 64 bit processor.

How do you find out if your computer is 32 bit or 64 bit

Windows XP

1. Go to the start menu.
2. Choose all programs.
3. Then choose accessories, then system tools.
4. Now choose system information.
5. See the screenshot below.

If it says x86 then you have a 32 bit processor. If the processor area mentioned ia64 or AMD64 then this means you have a 64 bit processor.  If it said Microsoft Windows XP Professional x64 Edition Version then this means it is a 64 bit operating system. However as you can see from above, it says Microsoft Windows XP Professional and the processor starts with X86 so therefore this is a 32 bit processor with a 32 bit operating system.

Windows Vista

In Windows Vista you can find out the same way. Start menu>Programs>Accessories>System tools>System information. You can also type the word system into the search bar in the start menu.

What are the advantages and disadvantages of having a 64 bit system?

• You will need to install 64-bit drivers for all your add ons like your printer, usb stick, digital camera, and more. This is why people have had problems with having a 64 bit system. However as time goes on the technology gets better and more refined... Soon drivers will be available for most devices.
• If you have a 64 bit processor and a 64 bit operating system you will have to have  64-bit software applications like office programs, picture editors, and so on..
• There is not much compatible software available at the moment, however this is changing.
• A Vista 64 bit operating system does not support any 32 bit software.
• An AMD 64 bit processor supports both 32 bit and 64 bit operating systems.
• Vista 64 bit operating system has major improvements on security features and kicks the 32 bit butt. New features that prevent and almost make system attacks impossible.
• Vista Home Basic 64 bit supports up to 8 GB of RAM, Vista Home Premium 64 bit supports up to 16 GB and Vista Business, Enterprise, and Ultimate 64 bit supports up to 128 GB, whereas 32 bit Vista supports 4 GB or RAM.
• A 64-bit processor is made with more advanced processes, have more features, and of course has faster speeds.

Notes:

• You can upgrade from XP 64-bit to Vista 64-bit, but not from Vista 32-bit to Vista 64-bit.
• If you are running a 64 bit operating system then we must presume you have a 64 bit processor as well.
• You can also type winmsd.exe into the run box for the system information box to come up.
• You can also press The WIN KEY and pause break to open system properties. Sometimes the information is there.
