Issues that this hotfix rollup resolves

Common language runtime (CLR) issues

Issue 1

When you press F5 to debug an application in Microsoft Visual Studio, Visual Studio crashes during the period after the application is compiled, but before it starts. 

Issue 2

When you run Microsoft SQL Server workloads that use large amounts of memory, out-of-memory errors occur even if sufficient memory is available.

Issue 3

When an application creates lots of threads for parallel processing, each thread may experience a leak of approximately 100 bytes.

Issue 4

When a computer has high workloads and low memory, Garbage Collector will compact the heap to recover memory. In certain cases, Garbage Collector will perform back-to-back garbage collection for applications. This behavior may cause the applications to be unresponsive.

Windows Management Instrumentation (WMI) issues

When an application uses the System.Management namespace to connect to a remote computer, a memory leak may occur. This issue occurs if the following conditions are true:
  • The application enters credentials for the remote computer by using the ConnectionOption parameter.
  • The application uses the ConnectionOption parameter as a part of the ManagementScope parameter to connect to the remote computer.
  • The ManagementScope parameter is used to perform operations.
