My wifi card is RTL8192CU. I could not find Microsoft Hosted Network Virtual Adapter either, even though I update my driver. But I have Hosted network supported : Yes. There is no HT mode in my wifi adapter's Property list. But I have EnableAdaptivity option in the list and I set it as Enable. netsh wlan start hostednetwork just works, at same time I still did not find Microsoft Hosted Network Virtual Adapter.
