Web browsers frequently update themselves and sometimes it’s hard to keep track of which version is on your computer. You can determine which version of Internet Explorer is installed on your computer with a few simple steps.
To determine the version of Internet Explorer installed on your computer:
1. Open Internet Explorer.
2. Click the Help menu, and then click About Internet Explorer.
3. Next to Version, the first number that appears (example: 5, 6, 7, 8 or 9) indicates the version of Internet Explorer installed on your computer.
