Samsung Notebook NP450R5E - Function Keys NP/Fn+F2 Issue on Windows 10 - Mute & Volume Control

Hello,
I have a Samsung Notebook laptop model np450r5e and I have Windows 10 installed on it, function keys np / Fn + F2 do not work on it, only from these combinations works mute and volume up. This reason I am 100% sure to reinstall windows. I found a similar post in which a man helped him, installed something, it just doesn't work.

Thank you in advance for your help.

Good clue in this link. Install Easy Display Manager - responsible for keyboard shortcuts, but from the manufacturer's website: http://www.samsung.com/pl/support/model/NP450R5E-X02PL

EDM was under Windows XP, under Windows 7 and higher was Samsung Settings. But Samsung has lost its customers laptops and software for systems newer than Windows 7 have not already posted on the pages.

Fortunately, however, the installation with the SW Update tool of the required package remained. SW Update can be downloaded from here: http://www.samsung.com/pl/support/swupdate/support-swupdate-popup.html

Enter your laptop model, fortunately in Samsung Update it has support for Windows 10. Deselect everything that is selected (default) and download only what you need (i.e. Samsung Settings, or if after this installation brightening / won't work) screen dimming, you can also download graphic drivers from this application).

Thanks, I think everyone will know what to do with such a problem
