Yes, there are a lot of Cyberlink process that remain open after you shut down the program or that start at boot. They are not harmful nor do they slow down your computer. There is no personal information.

For the ones that start at boot, do you know how to use mdconfig to prevent process from starting at boot? You can uncheck one at a time and see how it affects your computer. If you have problems, you can re-enable it. You can do that for each of the Cyberlink process that start at boot. Note, one you start Power DVD 12, that process may restart and not shut down after you close the program.

Unless there is something there that is a problem, my suggestion is to ignore it.

If you do have a problem, please discuss it and perhaps someone can help you. .

the problem is that when you next launch the program you get the following message: powerdvd is already running
so I have to end the program with task manager Powerdvd 12 remains running after closing.

That was not what I was expecting you to say. I'll have to think about it. Does it happen all the time? Are you using any USB devices at the time? .
