Windows operating system missing update KB2155311 to prevent performance issues on a NUMA based computer
<Details>
<Content>You are missing Windows operating system update KB2155311. This update prevents a problem related to working set trimming in applications like SQL Server when the computer has more than one NUMA node. The problem happens when a thread requests a large amount of memory within the 4 GB physical memory address range of a specific NUMA node and the requested amount of memory is not available. Review the knowledge base article and apply the operating system update.</Content>
