SendNotifyMessage and WM_SETTINGCHANGE not working anymore? RRS feed

  • Question


    Anyone got problems too with SendyNotify SendNotifyMessage(HWND_BROADCAST, WM_SETTINGCHANGE, 0, 0);

    I created an Applocker Rule app just like in the above link. These changes were pushed with the method RefreshPolicyEx and send to open processes with SendNotifyMessage. I cannot recall the exact date but this worked since day one but since a few weeks / months , open processes are no longer "receiving" or "handling" this event, as applocker rules are only applying when the explorer.exe processes are getting killed etc.

    Anyone experienced similar stuff? Is this a windows 10 bug or an wanted change by microsoft? I tried a thousand different ways to push my gpos to open processes (even iteraded all explorer.exe handles and send it directly) but nothing is working anymore.

  • Hi 

    Thank you for posting here.

    First, I think it is best for you to provide a English link instead of the other language link, because it is a English forum.

    Second, could you provide the code about your problem?

    Best Regards,
