Error: Windows cannot determine...(due to programs and devices not prompted).

Error:

Windows cannot determine if it can remove this device safely.

Cause:

Before undocking, Windows must remove the devices in the docking station. This is accomplished by prompting drivers and programs as to whether it is safe to remove a device. If safety cannot be determined, Windows will not undock.

Solution:

Select 'Device can be removed safely. Do not display this message again' after the test is run successfully.
