Why did m365Copilot.com or the Microsoft 365 Copilot app open automatically?
The keyboard shortcut combination Ctrl+Shift+Alt+Win opens the Microsoft 365 Copilot app or m365Copilot.com. Sometimes existing shortcuts, macros, and even drivers use this same keyboard shortcut combination. If you've relied on the Ctrl+Shift+Alt+Win shortcut to perform other actions in the past, you'll notice that using it launches the Microsoft 365 Copilot app now.
