Error after upgrading to windows 10 creators update !

[funandfly]

Hello everybody,
After upgrading to windows 10 creators update yesterday, I lost all of the applications as "Store, Calculator, People, etc.,..."
I've tried to sign in to the MS account but still nothing.
Please help me to solve this problem. Thanks so much.
