问题
I wrote an application using Qt under Windows 7. The application starts up with normal user privileges, but I want to gain the Administrator privileges because I want to modify the registry to auto-start the application.
How could I do this?
回答1:
Take a look at the MSDN sample: UAC self-elevation (CSUACSelfElevation)
Also, Wikipedia actually has a pretty good reference including information on the ShellExecuteEx() "runas" verb and application manifest for elevation requests.
回答2:
You should embedd correct manifest to your exe:

I know, you said using win32 API, but consider this standard and recommended way.
回答3:
You do not need administrator privileges to autostart your application.
Simply write the appropriate keys to:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
which does not require administrator privileges (unlike the same path under HKEY_LOCAL_MACHINE).
回答4:
Note that privileges cannot be changed while the program is running. It has to be killed and restarted with the correct privileges.
回答5:
to auto-startup the application, you don't need admin rights! Instead of adding the registry key under HKLM (where you need admin rights), use HKCU and you're fine.
回答6:
To make an application auto start in HKLM, the administrative privilege is needed. But the privilege of an application could not change while running.
So I made a new small application whose task is only write the registry to make the main application auto start.
The main application could call this application with ShellExecuteEx to require administrative privlege.
