When I click on application verifier for my windows 10 computer the command prompt comes up and then it goes away rather than the GUI opening. Is there something I need to enable to have this application work?

In a personal project, I want to display my application before (or above) the Windows Logon, ie just before entering the Windows password.
The application must "hide" the password entry screen. I used to launch an application at Windows startup but this after viewing the Windows desktop.
Is it possible to do this please? Should I create a Windows service that will launch my application?
Thanks for your help
If this is just a personal project on your own machine you could set Windows to autologon and then just run your application like a normal startup shortcut.
A NT service is the only documented way to run code before a user logs on. However, spawning a new process in another session and interacting with the Winlogon desktop and putting yourself on top of LogonUI.exe is going to be a hack.
I am running some Windows application as a service. This application used Office applications(Word, Excel). The service runs under specific user account.
Here is the problem:
When service is trying to use Excel, Excel is showing some dialog window which blocks the application from running. Since it's a service running in noninteractive mode you are not able to see the dialog window.
I was wondering if there is a way to get the title of a dialog window to understand the root cause of it.
I tried using EnumDesktopWindows but it didnt help.
Platform: Windows 10.
Thanks
Why doesn't -Dinstall4j.debug=true -Dinstall4j.logToStderr=true on windows result in messages in the console while it does on linux?
My cross platform installer runs as a normal user on linux and elevates on windows so it can install a service.
Linux
myinstaller.sh -Dinstall4j.debug=true -Dinstall4j.logToStderr=true
Console window fills with useful information
Windows
myinstaller.exe -Dinstall4j.debug=true -Dinstall4j.logToStderr=true
console window empty - I suspect the elevation, which seems to require a relaunch, is the cause.
If I run my installer from an Admin window I don't get my error case and don't see the console logging either.
GUI applications cannot write to the console under Windows, because they have no associated console.
If you select the "Windows console executable" property for the installer node on the Installer->Screens & Actions tab, you will see console output.
I am trying to programmatically open the windows 7 on screen keyboard (osk.exe) from my program.
I found a good guide for this on this page and it works quite well when UAC is turned off.
When UAC is turned on, it is not opening the program at all however, and I can't find why. No UAC prompt is shown when opening the keyboard from the start menu, so it doesn't appear to need administrative privileges.
Is it just because the executable is located in the windows system folder, and if so, is there another way to launch a program that would work?
The error returned is 3, ERROR_PATH_NOT_FOUND, possibly because 'sysnative' path is not working with UAC enabled.
Trying to run "osk.exe" without path also fails, with an error "Could not start the On Screen Keyboard"
Finally, running "C:\Windows\system32\osk.exe" fails with error code 5: SE_ERR_ACCESSDENIED when I tried to use it with redirection turned off (as suggested in this question)
I tested the c++ code sample you refer to in your message. The routine started either from VS devenv or as a standalone exe did always show the on-screen keyboard under any available UAC mode. My OS: Windows 7 Ult. SP1 64-bit.
I have developed an application that needs admin rights to execute. Running the application on Windows 7, the user always have to launch the application as "Run as Administrator" otherwise my application prompts the user that "you don't have administrative rights etc...". This is OK and understandable because of UAC in windows 7.
To get rid that the user have to set the application as "Run as Administrator". I updated my application's "app.manifest" and set
<requestedExecutionLevel level="highestAvailable" uiAccess="false" />
Which done the job for me.
But now, a security center symbol shield appears with my application's icon.
Now my question is "Why does this icon appear on my application, and what does it indicate?"
I tried marking another of my applications to "Always Run as Administrator" via windows but the same icon wouldn't appear with that application.
I want to understand the reasons and scenarios.
The shield is there to remind the user that if they double-click the exe to run it, they will get a UAC dialog. These dialogs should never be a surprise and if you get one you weren't expecting, you should really not consent to it.
The shield appears if you have a manifest that requests elevation (requireAdministrator or highestAvailable, but not if your manifest specifies asInvoker), and for certain file names. For more details see my blog entry (written at Vista time, but still applies to Windows 7) and MSDN articles on UAC and UI guidelines.
