6.1i iMPACT - PC4 driver prevents me from undocking Laptop PC with warning message of LPT port is being used


General Description: 

After installing ISE6.1i, I cannot undock Laptop PC even if I didn't invoke iMPACT after power-on. Windows gives a warning of LPT1 port being used.


To work around this issue: 


Bring up the DOS window and enter "net stop XilinxPC4Driver".  


Turn off the PC and undock.
