This article describes a hotfix package that resolves a problem that causes Windows Server 2012 R2 to crash when you're running Microsoft Remote Desktop Services (RDS).

Before you install this update, see the Prerequisites section.


On a computer that's running Windows Server 2012 R2 and Remote Desktop Services (RDS), you may experience a Stop error with message that resembles the following: 
Stop: 0x000000C2 (0000000000000007, parameter2, parameter3, parameter4)
Stop: 0x0000003B (c0000005, parameter2, parameter3, parameter4)

  • The Stop error 0x000000C2 might be caused by an error handling issue in the win32k.sys file.
  • The Stop error 0x0000003B might be caused by a synchronization issue in the dxgkrnl.sys file.
  • The parameters in Stop error messages may vary, depending on the configuration of the computer.
  • Not all "Stop 0x000000C2" errors or "Stop 0x0000003B" errors are caused by one of these issues.
