By default, Windows 10 allows an edge-swipe gesture to open Task View (essentially alt+tab) from the left and the Action Center (which allows Windows Settings access) from the right, even if Mondopad Shell is open.
The edge-swipe can be disabled via Group Policy:
- In Windows, right-click the Start button and select Run.
- Type gpedit.msc and press Enter.
- Navigate to Computer Configuration>Administrative Templates>Windows Components>Edge UI for system-wide, or User Configuration>Administrative Templates>Windows Components>Edge UI for current user.
- Edit and Disable "Allow edge swipe."
To completely disable the Action Center, navigate to User Configuration>Administrative Templates>Start Menu and Taskbar and Enable “Remove Notifications and Action Center.”
This will not disable notifications as they appear. Notifications can be disabled outside the Group Policy in Start>Settings>System>Notifications & actions.
