When you try to remove a modem using the Modems tool in Control Panel
while Device Manager is open, you may receive the following error message:
Rundll32.exe has performed an illegal operation.
CAUSE
The error message occurs because Windows 95 detects that the system
configuration has changed and sends a message to the Modems tool to update
its list of modems at the same time that the information for that modem is
being removed from memory.
RESOLUTION
To resolve this issue, use one of the following methods:
- Close the Modems tool and use Device Manager to remove the modem.
- Close Device Manager before you remove the modem in the Modems tool.
