Do you know why it's important to know what IE version you're using? Knowing what version number of Internet Explorer you have is helpful so you don't waste your time updating if you don't need to. It's also helpful to know what version of IE is installed on your computer so you know which tutorials to follow when you're trying to diagnose a problem, or maybe so you can communicate that version number to someone that's helping you solve a problem with IE. There are two ways to check your Internet Explorer version number. The first is through Internet Explorer itself, and is much easier than the second method that uses the Command Prompt. Instructions in this article apply to Windows 10, 8.1, 8, 7 and Vista. Find the Version Number With Internet Explorer The easiest way to find out what version of IE you're using is to check the version number from the About Internet Explorer dialog: Open Internet Explorer. If you're on Windows 10 and are actually looking for the version number of the Edge browser, see the section at the very bottom of this page for instructions on doing that. Select the gear icon or hit the Alt + X keyboard shortcut. Older versions of Internet Explorer, as well as newer versions of IE that are configured in a certain way, show a traditional menu instead. If so, select Help instead. Choose About Internet Explorer. The major version of IE, like Internet Explorer 11, is obviously apparent thanks to the big Internet Explorer logo that has the version appended. The complete version number of IE that you're running can be found next to Version under the big Internet Explorer logo. Use a Command to Locate the IE Version Number Another method is to enter the following command in Command Prompt to check what Windows Registry says about the Internet Explorer version: reg query "HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer" /v svcVersion The result should read something like this, where in this example, 11.706.17134.0 is the version number: HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer svcVersion REG_SZ 11.706.17134.0 How to Make Sure IE Is Updated Now that you know what version of Internet Explorer you have, you need to determine if updating IE is the next step. See how to update Internet Explorer for more on this, including information on the latest version of IE, which versions of Windows support which versions of Internet Explorer, and much more. Internet Explorer isn't just a browser, it's also the way in which Windows itself communicates with the internet to, for example, download patches to be installed via Windows Update. Keeping IE updated is important, then, even if you don't use it to surf the web. What About Microsoft Edge? Remember that Microsoft Edge is not the same as Internet Explorer. Here's how to check the version number of Edge: Select the three dots (...) at the top right. Go to Help and feedback > About Microsoft Edge. Look for the Microsoft Edge version number on the right side of the screen. Another way to get to this screen is from the settings. Search for version to quickly find Edge's full version number.
