An update changed my whole customized settings, can't change it back

Hey guys, my windows (10) was updated by himself and a lot of my settings were changed. Some I fixed and some I failed too. Can you help me change it back? I search for solution on the tutorial form but didnt find.

1. My colour settings were changed - from pure white to yellowish-white screen. Tried the steps on color managment but it remained the same. It explained here:




If you didnt understand the problem check the second video on 0:22 and 1:22. youll see how the colours changed
Unfortunately none of them help and my screen remained yellow instead of white.

2. Network Icon- I had a wifi (waves) icon on the task bar, and the update switched it with a airplane icon.
Tried to changed on Taskbar Settings --> Notification Area --> the 2 options didnt help.
Tried Settings --> System --> Notification & Actions --> I can see the 2 icons (wifi and airplane) but can't choose which one will represnt the network settings.
I'm trying to change it back because I want to know my wifi status by looking at the icon instead of entering it every time.

Thanks for your help!
