If some Windows Startup programs fail to run
A solution would be to have the Windows Scheduler run those applications. Consider this as the last option, since you need some time to make the necessary configuration, and it may not work for all of your programs.
Open the startup folder containing the shortcut to your application, delete this shortcut, and create a new one. You may think that this is irrational; why a new shortcut to the same application would work, while the old one failed? I don’t know why, but in my case this is what happened. There is no obvious difference between the two shortcuts, yet the new one works!
Notice the next solution, especially in case you have shortcuts with the “Run as Administrator” option enabled:
Watching the taskbar I saw a shortcut appear and immediately disappear, which made me think that Windows, for security reasons, did not allow this “Run as Admin” shortcut to run automatically. This is part of extreme security measures in Windows.
Restart your PC and enjoy, but take into account that after you disable “admin approval mode” the OS won’t let you open MS Store and update or use Windows 8 Apps! It is the same as disabling UAC, something you really wouldn’t like to do.
If you prefer to let UAC protect your system, and still be able to run your Admin shortcuts, perhaps it is time to create a UAC Whitelist!
