C:\config.msi, if created by windows installer, a reg key is made that is used as a security check. If you prevent that reg key from being deleted at cleanup and create that folder as user, you got an LPE. No junctions needed to abuse config.msi/rollback scripts btw.

So if you pack malware as .msi installer and spoof creator.. you could probably do all kind of crazy shit

No, this is about hijacking rollback scripts. Run the /fa (repair flag) on installers in c:/windows/installer and check procmon. You will see config.msi. You can take control of this folder and provide fake rollback scripts, doing malicious actions.
