For Internet Explorer 3.0 through 6.0, the browser is implemented in the Shdocvw.dll (Shell Document Object and Control Library) file. You can use the version of the Shdocvw.dll file to determine the version of Internet Explorer 3.0 through 6.0 that is installed on your computer. To determine the version of Internet Explorer 7, you must use the version of Iexplore.exe. To do so, follow these steps:
1. Click Start, point to Find, and then click Files Or Folders.
2. In the Named box, type shdocvw.dll, and then click Find Now.
3. In the list of files, right-click the Shdocvw.dll file, and then click Properties.
4. Click the Version tab.
5. Repeat steps 2 through 4, but in step 2 type iexplore.exe. If the version of Iexplore.exe is 7.x, then Internet Explorer 7 is installed. Use the table of Internet Explorer versions earlier in this article to compare the version number to released versions of Internet Explorer 7.
This table lists the different versions of the Shdocvw.dll file and the corresponding versions of Internet Explorer.
