Internet Explorer is a web browser that is built into all versions of the Windows operating system. If you're running a version of Windows (either Windows XP, Windows Vista or Windows 7), you've been using the 64-bit version. However, many people don't realise that the 32-bit version of Internet Explorer is also installed on your computer. You can easily switch between both versions using the "Start" menu.

Click "Start."

Click "All Programs."

Click on the icon that reads "Internet Explorer (32-bit)." This will launch the 32-bit version of Internet Explorer on your computer. When you're finished using it, click the "X" button to close the program.

Click "Start" again, followed by "All Programs."

Click on the icon that reads "Internet Explorer (64-bit)." This will launch the 64-bit version of Internet Explorer on your computer. When you're finished using it, click the "X" button to close the program.
