Svchost.exe crashes after you install the RDP 8.0 update in Windows 7

Applies to: Windows 7 Service Pack 1Windows 7 EnterpriseWindows 7 Home Basic

Symptoms



Issue 1

Assume that you install the Remote Desktop Protocol (RDP) 8.0 update on a computer that is running Windows 7 Service Pack 1 (SP1). You enable the RDP 8.0 host by using the Local Group Policy Editor. In this situation, the Svchost.exe process crashes intermittently on the computer.

Issue 2

Consider the following scenario:
  • You install the RDP 8.0 update on a computer that is running Windows 7 SP1.
  • The computer is configured to allow remote desktop connections.
  • You run an application that uses Windows Terminal Server virtual channel APIs (such as WtsVirtualChannelOpen and WtsVirtualChannelClose) to create and use virtual channels in an RDP session.
In this scenario, RDP static virtual channels do not work. Additionally, virtual channel communication fails in the RDP session if you do not reestablish the connection.

Notes
  • This issue does not affect other running RDP sessions.
  • This issue may have several different symptoms. For example, when you schedule several print jobs in a Remote Desktop Protocol session, the print jobs are deleted.

Issue 3

Consider the following scenario:
  • You install the RDP 8.0 update on a computer that is running Windows 7 SP1.
  • You run an application that uses Windows Terminal Server virtual channel APIs (such as WtsVirtualChannelOpen and WtsVirtualChannelClose) to create and use virtual channels in an RDP session.
  • The application tries to open a static virtual channel by using a channel name that does not exist.
In this scenario, the operation that opens the static virtual channel stalls for 10 seconds when the system tries to open the nonexistent virtual channel again.
