It's always nice to have a Windows Update... Odd I know, but it's exciting to find out what has been fixed or added.
The update today (Jan 8, 2013) involved security updates mostly, but also included some firmware updates for stability.
First off, the Windows RT Flash Player is not updated by Adobe. The Flash player is version 10 and updated by Microsoft. The downside is that Flash player on Windows RT is always behind and may not work on some sites. Although it is rare, I have run into this already. The upside is that I don't get an almost daily update from Adobe.
But in today's update, the Flash player was updated for IE10. This was done to fix a security hole. Benefit for me. I am seeing some improvement on sites that have required a higher version of flash.

Nothing exotic, nothing exciting.
