This is needed on Nano Server where VDS is not available. The logic for extending the volumes was decoupled from the plugin to a windows storage utility (VDS) alongside other extending utility which is available on Nano and versions greater than ws2012/w8 (WSM). According to the current Windows version, a suitable utility for extending will be loaded through a factory manager.
