• No longer uses BoxStarter, instead it is a plain PowerShell script
• Force re-installation of dependencies
• Can self-elevate when needed but in this case only PRODUCTION branch can be used

See #1429

When installing JDK:

jdk8 not installed. The package was not found with the source(s) listed.
 If you specified a particular version and are receiving this message, it is pos
sible that the package name exists but the version does not.

Final pause statement:

The term 'pause' is not recognized as the name of a cmdlet, function, script fi
le, or operable program. Check the spelling of the name, or if a path was inclu
ded, verify that the path is correct and try again.
