User-Agent Strings - MS IE - Full

We keep only the most current and major releases in the main page. This is the complete list of all MS Internet Explorer strings that we have ever found or received - including those on the main page.

MS Explorer

The 900 pound gorilla of the browser business. IE 10 is currently (2011) being previewed on windows 7. MSIE 9.0 is now released - if you are using Vista or 7 (or you can hang onto IE 8.0) . And for XP you have a choice of IE6, 7 or 8. And for the rest of us - tough. Seems Trident is the MS rendering engine name (since IE8?) - the equivalent of Opera's Presto and Moz's Gecko. Microsoft's MSIE history page (Link from Riley McArdle - thanks).

There are also strings for Windows CE/IEMobile in this section for those of a curious disposition (and yes, they should be in the mobile section. What do you expect - consistency?).

  1. If you're using the normal IE web browser from Windows Media Center PC..but NOT browsing from within the Media Center UI a version of "Media Center PC X.X" is added where "X.X":
    • "2.8" = Media Center 2004
    • "3.0" = Media Center 2005
    • "3.1" = Media Center 2005 + Update 1
    • "4.0" = Media Center 2005 + Update 2
  2. browsing the web from within the blue Media Center UI includes the above but adds additional information in the user agent string:
    • "MediaCenter 5.1.2600.2180" = Media Center 2004 or Media Center 2005 without Update 2
    • "MediaCenter 5.1.2710.2652" = Media Center 2005 + Update 2

Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 1.0.3705; .NET CLR 1.1.4322)

Explanation: This string has bit of history. We originally published it as a EudoraWeb string - since it was self identified by a site user as being that. However:

We got some email about this string suggesting that it was not eudora since it had no Eudora in it. To be fair the supplier of the string also voiced some doubt since it was left to the user to identify the string. If anyone can shed some more light on this topic - please email us and we'll publish.

We got some more comment which says it looks so much like a normal Win 2K that we've moved it. The suggestion is that both .NET strings are added when the MS WindowsUpdate system is used. Explanation from Matt Hair - thanks.
