title: Why application that require administrative privileges cannot run automatically on Windows startup(windows 7)?
body: <p>I have a application(which runs on windows7 and requires run as administrative) that need to run automatically when windows starts up, so i added a registry key under "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run" as usual, but my application won't startup automatically even the UAC dialog doesn't promtp, after search from google. I know i can use task scheduler to workaround this, but is there anyboday can tell me why the "run" registry way doesn't work? why the UAC dialog doesn't promtp? it is better if you can help to find a article from microsoft to explain this issue, many thanks in advance!</p>
