Is there a way to disable the RAD Studio IDE response to WM_WININICHANGE ?

Is there a way to disable the RAD Studio IDE response to WM_WININICHANGE ?

The Enterprise is spamming me with these every 15 minutes (a side effect of policy policing and software update pushes), causing the IDE to hang for 30 seconds while it flashes the toolbars.

  1. Write an IDE plugin. In that, find the main window. Replace its window procedure with one that swallows WM_WININICHANGE. Or perhaps it’s the application window that is handling this. Again, you can find that window, and replace the window procedure. Or perhaps there’s WH_CALLWNDPROC hooks.


    Were it me I think I’d just pull the network cable and get on with my work. Just imagine how productive you’d be!


  2. No slideshow. Static picture. Joaquin Menemene – What configurations would that be? I see no such behaviour.


    The messages arrive when the backgroundTaskHost.exe, UsoSvc (Update Service Orchestrator for Windows Update), and gpsvc (Group Policy Client) run.


  3. Lars Fosdal as far as I remember, it’s something that happens with Win8 and Win10 when style changes (don’t remember if it happens on Win7 as well, it’s possible)


    There’s a setting on Windows that configures the style to change depending on background colors so when you also sets the background up to change periodically, it will change style color that will make Rad Studio go crazy for some seconds


    The bad thing is that this is the default setting on Windows 10
