If you'd rather manually check, you can do so by following these steps for your operating system. Note that detailed instructions are also available from Microsoft at the same link.

Windows 7 and Vista

  • Open the Start Menu.
  • Type "System" in the search field.
  • Select "System" under "Control Panel."
  • In the System window that opens, consider the value corresponding to "System type" in the "System" section.
  • "64-bit Operating System" will be listed for 64-bit versions, and "32-bit Operating System" will be listed for 32-bit versions.

Windows XP

  • Open the Start Menu.
  • Click "Run."
  • Type "sysdm.cpl" and press OK.
  • Click the "General" tab.
  • Under system, the operating system will list "x64 Edition" as part of the version if it's a 64-bit version. If it does not mention that, it a 32-bit version.
