I've had to migrate from AutoHotKey to AutoIt due to technical limitations, and I can't get my favourite, most-used script that I use every day, to work because Windows Hotkey Combinations work in AutoHotKey, but not in AutoIt. I need to figure out how to amend this.

The script itself doesn't have much to do with the topic at hand (centers a window), but rather how each program registers its hotkeys. In AHK, for instance, registering a hotkey for the non-reserved combination "Windows + C" works splendidly. All you have to define is:

#c::

In AutoIt, registering the same hotkey for the non-reserved combination doesn't work at all (returns 0 indicating it failed to set the hotkey):

HotKeySet("#c", "_Center")

I made sure that during testing, the hotkey isn't consumed by another app / script already.

That begs the question, what does AHK do differently in this regard and how can I get my hotkey + script to work just like it does in AHK?

Thanks to anyone willing to help in advance.

#c is reserved by Cortana

It might be, but why is AutoHotKey able to execute it? According to this page, AHK manages to override the windows keys somehow. Any idea on how that could be applicable in AutoIt?

I may just end up disabling all the hotkeys by following the first instruction on the page I linked and re-implement the default Windows hotkeys that I want. I would love to find an alternative, though. Maybe some registry entries that disable specific windows hotkeys that could be implemented in a UDF?

I was right! I did some research and found this, which essentially does exactly what I want. I found out that this method requires a restart of the Windows Explorer, which I can live with, I guess.

If I have the time & energy, I may even post some sort of UDF in here 😃
