Hello Graeme WARD,
When you say Excel always opens in full screen, do you mean the Excel window is simply maximized and fills the desktop, while the ribbon and title bar are still visible, or do those controls disappear as well?
That distinction matters because they are different window states and the fix would be different.
If Excel is simply opening maximized, please let me know whether restoring the window to a smaller size, closing Excel, and reopening it causes Excel to become maximized again.
If the ribbon or other Excel controls are disappearing instead, try Ctrl + Shift + F1 once.
