Why does this UAC bypass technique only work on Windows 10 and not on Windows 7?

The difference lies in the executable manifest of sdclt.exe. On Windows 10, sigcheck shows `level="requireAdministrator"`, meaning the process automatically requests elevation. On Windows 7, sdclt.exe has `level="asInvoker"`, so it runs with the same integrity level as the parent process and cannot be used for privilege escalation. This was verified using the Sysinternals tool sigcheck as detailed in the article.
