Stop error 0xAB if HID is installed in Windows 10 Technical Preview or Windows Server Technical Preview

S’applique à : Windows Server Technical Preview


This issue occurs when you switch between users or disconnect from a terminal services session.

Note HID means a human interface device, such as a keyboard or mouse.

Additionally, you receive a Stop error message that resembles the following:
Stop: 0x000000AB (parameter1, parameter2, parameter3, parameter4)

  • The Stop error 0x000000AB describes the SESSION_HAS_VALID_POOL_ON_EXIT issue.
  • The parameters in this Stop error message vary, depending on the configuration of the computer.
  • Not all 0x000000AB Stop errors are caused by this issue.


This issue occurs because of a memory leak when the system tries to close a user session.
