make exe file automatically run as administrator

In the properties of the exe you can set a compatibility option for this. There is also a PE within the SysInternals Suite called ShellRunAs.exe that may prove useful.

update: For system executable files that will not let you edit compatibility options you might be able to work around this by creating a shortcut of that exe and then within the properties of that shortcut you can select "Advanced" and set "run as admin".

If that does not work for your use case then the solution would likely require custom registry edit, which might not be appropriate to mention here.
