Laptop - which of them can I delete?

Can I deinstall everything I have marked? Yes or no?

if not everything I have marked, then please say which one has to stay there. So what is important for the laptop.

As a precaution, I would leave the Dolby Audio there. Could be part of the sound card driver. The rest can go when you don't need them. Incidentally, also all of the Office language packages. I would only keep those that you need.

I would also say leave the stories with Dolby alone, could be part of the sound driver. If you are not watching BluRays on your computer, you can also make the Cyberlink programs disappear.
