I want to disable two shortcuts specifically.

`F1` and `WIN`+`=`

[This page](http://www.geoffchappell.com/notes/windows/shell/explorer/globalhotkeys.htm) describes how to disable some `WIN`+`X` keys if `X` is letter. But it does not work if I just enter "=" in the registry key DisabledHotkeys.

Any suggestion please?

EDIT: Direct dealing with the registry (without an external software) is much preferred.
