_BlockInputEx.au3 - block keyboard strokes

[kayser2008]

Hy i was triing to use this funcion to desable the use of the "windows" or "F1" key and wosw doybg this way but the "F1" i allready block but seams that i can´t get there with the "windows" key

#include <_BlockInputEx.au3>

if $tempo > 1 then

_BlockInputEx(3,"","0x5C|0x5D|0x71")

endif

the codes are referent to Left windows , Right windows and F1

Is this possible?

The codes are right? If no whish key codes should i use?

Is there another way to do this?

Thanks
