Important

  • All updates for Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2 require update 2919355 to be installed. We recommend that you install update 2919355 on your Windows RT 8.1-based, Windows 8.1-based, or Windows Server 2012 R2-based computer so that you receive updates in the future.
  • If you install a language pack after you install this update, you must reinstall this update. Therefore, we recommend that you install any language packs that you need before you install this update. For more information, see Add language packs to Windows.

Quality and reliability improvements

For ASP.NET

ASP.NET sequentially executes requests that have the same SessionID. This means that you may see the requests collecting in the queue if there are lots of concurrent requests that have the same SessionID. After you apply this fix, you can limit the number of the requests in the queue through the following appSettings entry:

<appSettings>
   <add key="aspnet:RequestQueueLimitPerSession" value="50"/>
</appSettings>

 

For CLR

If you arrange an array of struct A and an array of struct B as SAFEARRAY and struct A and struct B have identical GUIDs, a memory leak may occur.

Note This update also contains cumulative updates that were released previously, starting from October 11, 2016.
