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.*
Windows 10 apps will not start
Re: Windows 10 apps will not start
[Figured it out](http://codecorner.galanter.net/2015/08/05/solution-windows-10-unable-to-start-appstore-apps/). Pour une raison quelconque `ALL APPLICATION PACKAGES` compte lost access to `C:\Program Files\WindowsApps` dossier. Once I added it - problème was résolu, appstore apps launch normally.
