Ignore Window

[ps1cscpp]

I wan't that a specific a application has access to the complete list of open windows just like the dexpot feature "Desktop Windows". I don't know if that feature is implemented, I search as "ignore window in dexpot" but I don't found any result. I wan't to use an application switcher that search for title name. There are a lot of App that do that and even is incredible simple create one using Autohotkey, the problem is that the pool of open windows is not complete, only the windows of the active desktop is visible to any of those apps. I have tested this:
ISwitcher
Switcheroo
And my own incredible simple script in autohotkey:

InputBox, myvar, , , ,600,100
SetTitleMatchMode, Regex
regex= i)%myvar%
WinActivate, %regex%

So how can a application ignore Dexpot?
You could ask, Why don't use the already existent feature? well i don't like it for the lack of hotkeys, i know that i can set a hotkey to launch "Desktop Windows" but in that window i have to manually click in the search field and then again manually click in the result. I wan't to switch to any window without touching the mouse

So how can a application ignore Dexpot?

Only by changing the application itself (to use the Dexpot plugin system).

Have you tried the "Task switcher" hotkey, WIN+Q by default?
