Take control of Alt + TAB, Ctrl + Alt + Del and Ctrl + ESC.
 

Hello. I am trying to modify Win7 so that WinUAE and AmigaOS 3.9 start when I start my computer. There was no problem with changing the shell. But I would like to disable the key combinations mentioned in the title. Is it possible for WinUAE to completely take control of them? Generally under AmigaOS I use YAWS which switches windows with Alt + TAB. It works with both LAlt and RAlt. But when I forget and use LAlt it switches me to the windows desktop. Does anyone have proven methods that will best disable all key combinations under Windows 7?

you could use autohotkey (eventually autoit3 too) to redirect or to disable some of the unwanted keys.

Autohotkey is running (here) with windows 10.

and this is a part of the script, which i'm using to disable some of the keys:

(alt tab in this example)

Those key combinations can't be disabled by applications without admin privileges and/or custom drivers.

Some 3rd party utility is needed, like one mentioned above.

Thank you for your answer. Looks like your method is working fine. When I pressed Alt + TAB from Workench, WinUAE was not minimized. Additionally, the Alt and TAB keys work fine under AmigaOS. Are there any other scripts to disable the Alt + F4, Ctrl + ESC, Shift + ESC and Ctrl + Alt + Del combinations?

ALT+F4 can be disabled in WinUAE by enabling "Use CTRL-F11 to quit" option. Other 3 are handled by Windows and applications can't override them.

Apart from Ctrl + Alt + Del, I was able to lock down most of the key combinations. Here is the script:

Only the Win + X combinations are disabled in the system registry.

To deal with Ctrl + Alt + Del, I go to the Input tab and add a secondary mapping for Numpad0 to target Del, with Ctrl + Alt as qualifiers. Then I can press Ctrl + Alt + Numpad0 (the key immediately to the left of Del on a standard numeric keypad) to send Ctrl + Alt + Del to WinUAE without Windows intervening. I use this to do a warm-reboot when running PC Bridgeboard emulation.
