NoelC Posted May 11, 2016 Share Posted May 11, 2016 Hi, Recently on one of my Win 8.1 systems I spotted Internet Explorer contacting two Microsoft servers I didn't expect it to be communicating with: iecvlist.microsoft.com (even though "use compatibility list" is disabled) r20swj13mr.microsoft.com The former is Microsoft's "compatibility view list" server, and apparently IE sends data to it even though this is set. Why am I not surprised at yet another breach of privacy? Anyone know what r20swj13mr.microsoft.com is used for? I've blocked it and so far I see no downside. -Noel Link to comment Share on other sites More sharing options...

But i have fair collection of scripts and programs which bock telemetry and every single one of them adds that address in hosts file. Hope it helps a bit.

NoelC Posted May 12, 2016 Author Share Posted May 12, 2016 Thanks. I've blocked it similarly, with no apparent downside. -Noel Link to comment Share on other sites More sharing options...
allen2 Posted May 13, 2016 Share Posted May 13, 2016 (edited) Both servers seem to be used for the same purpose: the dns alias ie9comview.vo.msecnd.net is shown for both of them when you do a nslookup. So as you disabled the check on IE side, both should not be contacted anymore. Edited May 13, 2016 by allen2 fixed typo Link to comment Share on other sites More sharing options...
NoelC Posted May 13, 2016 Author Share Posted May 13, 2016 Right, but they are contacted nonetheless. Hence the block by entries in the hosts file. # Unwanted Microsoft site contacts from IE 0.0.0.0 iecvlist.microsoft.com # Compatibility view list, contacted even though deconfigured 0.0.0.0 r20swj13mr.microsoft.com # Unknown why this is contacted by IE -Noel Link to comment Share on other sites More sharing options...
