Extension Pack updater should be able to detect if an user has admin privileges or not.

Today I started Virtual Box in Windows 10 as a non administrative user and I was asked to download a new version of the Extension pack i installed previously. Guess what. I fail, because Virtual Box is not able to ask for an administrators password by it self. That may be good for some security reasons but There must be a better way to do the extension pack update

Your deduction is wrong. VirtualBox actually is able to ask for the admin password and it does so on Windows 10 version 1607 (build 14393.0). Which Windows 10 version are you using?
