The F1 key is the universal help key in Windows, and it’s no different in Excel. Pressing F1 will open the Microsoft Office Help window, which can be helpful if you’re stuck and need some assistance. However, some users may find that they accidentally press the F1 key often, which can be annoying. If you’d like to disable the F1 key in Excel, there are a few methods you can try.
One method is to remap the F1 key to another function using a third-party utility like SharpKeys or AutoHotkey. This will essentially “swap” the functions of the two keys – so pressing F1 will now perform the action that another key would normally perform, and vice versa. This can be handy if there’s another key on your keyboard that you don’t use often.
Another method is to disable the F1 key entirely using a registry edit. This isn’t recommended for most users, as editing the registry can be dangerous if you don’t know what you’re doing. However, if you’re comfortable making changes to the registry, here’s how to do it:
regedit, and pressing Enter. Click Yes when prompted.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\Parameters. If you don’t see the

Double click on
