Unnecessary software to uninstall?

Hello everyone,

So here's the thing, I bought a Samsung notebook and I see that there are really a lot of software in "Programs and Features" and I would like to know which ones are useless and which ones I absolutely need to keep since I don't use these programs or at least I don't see them.

Here is the list of software:
- Atheos Client Installation Program
- CyberLink (there are quite a few, it's the webcam I believe)
- Easy File Share
- Easy Migration
- Easy Settings
- Easy Software Manager
- Easy Support Center 1.0
- EDTWare PS/2-X64 10.0.7.2_ WHQL
- Multimedia POP
- NVIDIA GeForce Experience 2.1.2
- NVIDIA PhysX System Software 9.13.0725
- Realtek Ethernet Controller Driver
- Realtek High Definition Audio Driver
- Samsung Recovery Solution 5
- Software Launcher

There you go, I know the list is long but if you see a software that is unnecessary, please let me know.
Thanks!
