Sign your application for HKLM/Init

I had made a test application in [HKLM\Init and database status] for trying to figure out the database status in boot up sequence. And as I said in that post, the application run fail when I try to put it earlier than services.exe (launch60).

And I found a solution about the issue: signature.

I still cannot find any document mention about this limitation, but after I sign my test application with my develop certificate, the application can be run at anywhere I wanted.
