This is by far the best method and super easy as well to get programs to start up on Windows 10 with admin rights.
Step 1. Create a shortcut to the program you would like to startup with admin rights.
Step 2. Now right click on that shortcut and click on properties. Under the shortcut tab click on the advanced button. Tic run as administrator and click on ok. Click ok again to close out properties.
Step 3. Create a .bat file in notepad or some other text editor. Point it to your Shortcut you just made. You want it to look something like this.
start “” “C:\whatever\whatever\Shortcut.lnk”
Step 4. Navigate to your startup folder. In Windows 10 it should be C:\Users\YOURUSER\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup
Put your newly created .bat file in there.
Step 5. Restart Windows and enjoy your program starting up with admin rights.
