Just upgraded my Windows 8.1 Pro (Lenovo W540 laptop) to Windows 10, tout went smoothly, all my paramètres and installé apps preserved and work sans a hitch.
The seulement problème is - Windows's own apps - Calendar, Mail etc. even Windows AppStore - ne va pas launch. When I run them I very briefly see a window flashing and ensuite rien happens après that.
Une idée de what's going on and comment fix it?
EDIT: Seeing bunch duse in Event log: Activation of app Microsoft.WindowsStore_8wekyb3d8bbwe!App échoué avec erreur: Access is denied. See the Microsoft-Windows-TWinUI/Operational log for additional information.
