Questions that everyone has Xbox game bar minecraft for windows 10 and I can't upload...

Hi I have problems with game bar windows 10, problem 1 When the game bar is running, it uses a lot of RAM and CPU and hard disks, so when I am in the game, either the game bar slows down the game or the game bar slows down, and sometimes it pcs my PC
into the regiment. Problem 2 I can't upload game clips and screenshots (Captures) to Xbox live (activity feed) or clubs it says (this app It no longer supports this feature) is Xbox i tryed with xbox console companion and xbox console companion-beta But it
still did not work problem 3 I bought the minecraft for windows 10 starter version in another account, but when I use it on a new pc, it says Unlock full game, but why? Please reply. I'm waiting and your feedback is important to me. Thanks to Microsoft and
Xbox.

:)
