How to create a shortcut to launch an App with admin privileges from the cmd-line?

You can add a registry-key that tells windows to execute your program as admin:

Under HKCU\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers, just add a key(REG_SZ) <Path to your exe> with the value RUNASADMIN. When you launch your exe, you will be prompted for admin-access.

With that, you can simply create a normal shortcut to your executable like you would do it with Inno-Setup.

If you want to do so via a cmd or a batch-file, you can use the following command:

reg add "HKCU\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers" /v "<Path to your exe>" /t REG_SZ /d RUNASADMIN
