Reporting Sites Which are Incompatible with IE11

With Internet Explorer 11, we invested a lot in improving the overall compatibility of web sites. In my experience, the single biggest change we made was to the user agent string. The IE11 user agent string no longer contains the string MSIE. This has turned out to be terrific for sites which used to black…


Troubleshooting and Fixing Session Cookie Problems in IE11

Another browser, another version check crisis… So, like many of my esteemed nerdly readers, I pushed “go” on upgrading to the Windows 8.1 preview the first opportunity that I had. And, naturally, the first thing I started doing was finding the broken stuff. Unfortunately, it didn’t take me long. We have an internal conference twice…


Windows 8 App Compat on The Edge Show

While at TechEd a few weeks ago, I had a chance to sit down with my friend Joey and chat about where we are with app compat, which was briefly before Windows 8.1 was released so we weren’t chatting too much about that yet. That recording is up on the web now as part of…

Finally, users of Windows devices have a full fidelity experience using the Weight Watchers online tools! Enjoy, and terribly sorry for the delay in going live with this…


Update on the Weight Watchers Mobile Site on IE10

Back in December, I blogged about the failure of Weight Watchers Mobile on IE10, which affects peoples’ fancy new Windows Phone 8 devices, not to mention their Windows RT devices like the Surface RT. In the interim, I’ve disabled the compat view list on my Surface (there isn’t an option to do that on the…


Windows Compatibility Center Supports Windows 7, Windows 8, and Windows RT

While Microsoft isn’t the final arbiter on whether an application is “compatible” with any given version of Windows (see: http://blogs.msdn.com/b/cjacks/archive/2010/01/12/what-does-it-mean-to-be-compatible-with-windows-7.aspx) a few years ago we launched an initiative to help reduce a bit of the burden of looking up every app you care about by aggregating some of that data into a single website, which…
