had been searching a while for a procedure or script that could remove Cisco
VPN client without blue screening the system or leaving legacy bits and pieces
on the system, with no luck.
I spent some time reverse engineering how the application works and have
written a procedure to remove Cisco VPN Client (ver 4.0.5) for Win XP-32bit,
which I have tested in a VM environment successfully.
am working on Windows 7 removal procedure so watch this space.
hope this help.
