Just upgraded my Windows 8.1 Pro (Lenovo W540 laptop) to Windows 10, everything went smoothly, all my settings and installed apps preserved and work without a hitch.

The only issue is - Windows's own apps - Calendar, Mail etc. even Windows AppStore - won't launch. When I run them I very briefly see a window flashing and then nothing happens after that.

Any idea what's going on and how to fix it?

EDIT: Seeing bunch of these in Event log: Activation of app Microsoft.WindowsStore_8wekyb3d8bbwe!App failed with error: Access is denied. See the Microsoft-Windows-TWinUI/Operational log for additional information.

Figured it out. For some reason ALL APPLICATION PACKAGES account lost access to C:\Program Files\WindowsApps folder. Once I added it - problem was solved, appstore apps launch normally.
