*RESOLVED - Read till the end*
I cannot change specific settings from start menu.
I cannot change the location of tiles, cannot add or remove tiles, cannot resize them, can't move them around.
These are settings which I can't change from settings menu in start.
1. Show more tiles option in Settings->Personalization->Start is turned gray i.e. can't be changed.
2. This is written on the top of the page. "Some settings are managed by your organization".
Only setting that i can access is to turn a live tile off by right click on that live tile. Right-click->more->turn live tile off. Nothing else available.
I have this problem in start menu since I've updated my windows 10. It was fine when I updated it from 8.1 but after some updates of Win 10, this problem is there.
Using Windows 10 Version 1511 (OS Build 10586.71)
Fortunately my problem has been solved but unfortunately none of the above mentioned procedures (of editing registry or something else) worked. Instead it was all the same no matter what. But then some update came for windows and as usual i updated it and suddenly problem was gone. Now i can edit start menu tiles as i want.
If you are interested then this is the update that resolved my problem
Cumulative Update for Windows 10 Version 1511 for x64-based Systems (KB3147458)
Now i'm running Windows 10 Pro version 1511 OS build 10586.218
Hope this helps someone.
