This has happened on 2 machines that I am aware of, When you click on the Control Panel Icon from the Start Menu, it opens and then closes imeadiately. However the Admin Tools option can be launched from the RunBox. Control Panel we have tried to launch from the RunBox with no success..
System Specs are:
Machine #1
Gateway GL5674 Desktop
Windows Vista 32bit Home Edition
AMD Athlon Dual Core CPU
Smart Media reader
Built on Sound and Video
3gb Ram
250gb SATA Hard Drive
Machine #2
HP Laptop
Windows Vista Business Edition
Intel Core Duo 2.33
CD Rom Drive
Hard Drive
2gb Ram
80GB Hard Drive
Express Card Slot
This doesnt seem to be a machine specific issue,
These 2 customers stated windows defender was possibly
disabled.
This is all the info I have available.
In the past the only solution was to format and reload the OS.
