How to set up Windows 10 ad hoc wireless hotspot

If you came to Windows 10 directly from Windows 7, you might have noticed that ad hoc Wi-Fi (routerless) connections are no longer available. The user interface for setting up an ad hoc connection does not exist any more in the Network and Sharing Center nor in the Settings app. However, there is a way to make your Windows 10 PC behave like a wireless access point/hotspot.

Where is the ‘ad hoc’ wireless connection feature in Windows 8 and Windows 8.1

If you 'upgraded' from Windows 7 to Windows 8 or directly to Windows 8.1, you might have noticed that ad hoc Wi-Fi (computer-computer) connections are no longer available.  The user interface for setting up an ad hoc connection does not exist any more in the Network and Sharing Center. This can be a bit disappointing. However, with Windows 7 itself, a substitute feature was introduced which is a better replacement for ad hoc wireless connections.
