How to Determine the Bit Count for a Windows Computer
This wikiHow teaches you how to determine your Windows computer's bit count, which typically will be either 32- or 64-bit.
Part 1Windows 10 and 8
1Click the Windows logo in the bottom-left corner of the screen. The Start window will pop up. You can also just right-click Start (or press ⊞ Win+X) and click System in the resulting pop-up menu. If you do this, skip the next two steps.
2Click the gear-shaped icon in the bottom-left corner of the Start window. This will open the Settings window.
3It's a computer monitor-shaped icon in the Settings window.
4This tab is at the bottom of the left-hand column of options. Doing so brings up a list of your computer's attributes.
5It's near the bottom of the "Device specifications" section toward the bottom of the window. You'll see either "64-bit" or "32-bit" to the right of "System type"; this is your computer's bit count.
Part 2Windows 7
1Either click the Windows logo in the bottom-right corner of the screen, or press the ⊞ Win key.
2It's on the right side of the Start window. Doing so prompts a drop-down menu. If the My Computer app is on your desktop, you can right-click it instead. If you're using a laptop with a trackpad, tap the trackpad with two fingers instead of right-clicking.
3This option is near the bottom of the drop-down menu.
4It's below the "Installed RAM" heading on this page. You'll see either "64-bit" or "32-bit" to the right of "System type"; this is your computer's bit count.
