RESOLUTION

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it.

To resolve this behavior, use one of the following methods:

Configure Program That Dials ISP Not to Start Automatically

Configure the program that automatically checks for updated components or Web pages so that it does not start when Windows 95/98 starts. To do so, refer to the documentation included with the program.

Remove Program That Dials ISP from the StartUp Folder

  1. Right-click Start, and then click Open.


  2. Double-click the Programs folder.


  3. Double-click the Startup folder.


  4. Drag the program that automatically checks for updated components or Web pages from the Startup folder to another folder. This prevents the program from starting when Windows 95/98 starts. To start the program once you move it from the Startup folder, locate and click the program on the Start menu.
