The FSRM UI stops responding when there are many storage reports to monitor on a server that is running Windows Server 2012 R2

On a server that is running Windows Server 2012 R2, you view the Storage Reports Management node of the File Server Resource Manager (FSRM) snap-in in Microsoft Management Console (MMC). When the number of storage reports to monitor is sufficiently large, a CPU spike can occur on the server and performance significantly degrades.


By default, the FSRM MMC snap-in File Reports status is refreshed every minute. This is designed for only a few reports. Generating lots of reports may cause the FSRM UI to stop responding.


To resolve this problem, apply this hotfix to the computer that is running Microsoft Management Console.
