Check if your CPU is either 32-bit of 64-bit in Windows Vista

Today or tomorrow I will be upgrading from my current Vista to Windows 7 and I needed to check which version of the OS the install.

To check whether my CPU was 32-bit or 64-bit, here's what I did (in Vista):

 First open up the System Information tools from Accessories > System Tools

Then from the System Information, look for the System Type Row, and there you will have your answer:

• x86-based PC: 32-Bit Computer
• x64-based PC: 64-Bit Computer
