Windows charms bar is operated by explorer.exe. So if your app can run without it then you can hack around it by first disabling the autorestart of explorer.exe via (run as administrator):
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v "AutoRestartShell" /t REG_DWORD /d 0
Then the lines below represent my launch.bat
- which works in the end as expected:
;; kill explorer (this disables all windows functionalities
taskkill /f /im explorer.exe
;; start your kiosk app - should block the batch execution (so explorer.exe doesn't get executed at the end)
"\path\to\your\app.exe"
;; after you close both the app window and the opened chrome window relaunch explorer.exe to give back the functionality to windows
explorer.exe
I use the approach outlined above to let a keyboardless kiosk app run. Because with a keyboard you can still close the app with alt+f4.
