Bug1?:
Hi. I have the Unity game on windows store (PC).
PlayerPrefs on client is empty. Why? Bug?
Bug2?:
Switching input language (Alt+Shift, Ctrl+Shift, in bottom bar) not working on some computers (Windows store appliacation PC)
Bug1:
Could you elaborate? Which Unity version you use. The bug 1 shouldn’t be happening, maybe you’re submitting your app as new game?
Go to C:\Users<user>\AppData\Local\Packages and check the guid for your original app and updated, it should match.
If it’s the same, could you also attach UnityPlayer.log when you launch updated app.
Addtional info playerprefs are stored in C:\Users<user>\AppData\Local\Packages in C:\Users<user>\AppData\Local\Packages<package>\LocalState\playerprefs.dat, you could save this file somewhere and copy it when updated app is installed, see if it’s able to read playerprefs then.
Bug2: Need more information, are you able to reproduce this yourself, which Unity version.
Unity 5.4.2f2
I am submitting new version for update (not new game)
guid is same.
I found that It does not depend of updates. PlayerPrefs.GetString always return empty string after i restart game.
PlayerPrefs.Save() not solve my problem.
Log from first start updated app (i am not found error or warnings):

this is that? Unity Issue Tracker - [WSA][UWP] PlayerPrefs aren't saved between runs
My version: 5.4.2f2
That bug was fixed in 5.4.2p1, see if that version fixes your issue.
not fixed in my version (5.4.2f2).
That’s why I said try 5.4.2p1, which is higher version than 5.4.2f2

True. Bug 1 was solved in patch!!
Bug 2 not. I don’t know why.
I can not understand the Unity versions p? f? 2p1, 2f2 
P.S. How you find time for wokring with Unity and reply at questions on this forum? Or this is part of you work?
Unity takes a long time to compile after you change code…
f - means release version
p - means patch version, basically a release with patch fixes
Regarding Bug2, you should submit a bug report, with small repro attached, and specifying where this issue occurs
Not sure if this is related to your Bug 2 , but when using Application.systemLanguage in Windows value comes from Region → Formats instead of your language settings.
Not sure if this is a bug , or a feature
