However, Microsoft lost a very large lawsuit (over $500 million) with a small company called Eolas several years ago and as part of the settlement of that lawsuit, Internet Explorer is no longer allowed to open
Word Documents, Excel spreadsheets, PDF's and other similar files in the browser window.
So far, Internet Explorer is the only browser that's been restricted that way, not Firefox, Opera, or browsers for other OS's such as Apple's Safari. But in Windows/IE, the browser windows cannot be used and the document is opened in a new window. Older versions of IE did not always get "fixed", so some of them will, but anything that old may have other problems by now.
