See if these notes apply to your system:
If you are using msconfig and you see something along the lines of:
An Access Denied error was returned while attempting to change a service. You may need to log on using an Administrator account to make the specified changes.
If you now or have ever had an HP printer installed, the problem is most likely the HPZ12 Service.
The msconfig changes seem to work, but the error message is annoying.
There is a possibility you will lose communications with your HP printer if you want to prevent the error message. This may not be a problem if you don't care about the communications or never use those HP features.
You can also live with the message, knowing the changes really worked or you can contact and ask HP and they will usually suggest reinstalling Windows (these kinds of suggestions usually mean nobody knows what to do!).
Depending on your comfort level with making system changes, here are two solutions.
There is no undo or quit without saving option in the registry editor.

Remember, msconfig is not a startup manager. msconfig is a troubleshooting tool.
Another possibility is to use some third party startup manager tools to make your general configuration changes.
