How to Create a WiFi Hotspot in Windows 10
Just like in modern smartphones, Windows 10 machines that can connect to Wi-Fi networks are capable of creating their own Wi-Fi hotspots. The most common use case of doing this would be to share Internet. Some other reasons would be to play local co-op games and to share huge files.
This tutorial will show you how to create your own mobile hotspot. You can choose between the visual and command-line way.
1. THE VISUAL WAY
We start by launching the Windows Settings app. Search for settings in Windows start menu and click on the first result. Then click on Network and Internet.
Next, click on Mobile Hotspot and then the Edit Button, to edit the default SSID (Wi-Fi hotspot name) and password.
On the window that pops up, update the default network name and password to something else, for security. And click on Save.
And then we can turn on the hotspot.
That is all, the mobile hotspot is created and running now. We can connect up to 8 devices to it.
2. THE COMMAND LINE WAY
First, we have to launch a Command Prompt window with admin rights. For that, search for cmd in Windows start menu. When you see Command Prompt as a result, right-click it and choose Run as Administrator.
Or, do 
+R to launch the Run Dialogue and type cmd in it. Then do Ctrl+Shift+Enter
I. SET NAME AND PASSWORD
To, create a hotspot with the name Hotspot001 and password aSimplePassw0rd, run the following command,
netsh wlan set hostednetwork ssid=Hotspot001 key=aSimplePassw0rd
The SSID of the hosted network has been successfully changed. The user key passphrase of the hosted network has been successfully changed.
II. ENABLE THE HOSTED NETWORK
Now, we need to enable the hostednetwork. This is like the master switch of the hotspot.
netsh wlan set hostednetwork mode=allow
The hosted network mode has been set to allow.
III. START THE HOTSPOT
Start the hotspot with the following command,
netsh wlan start hostednetwork
The hosted network started.
And that is all, hotspot is created and running now. We can connect up to 100 devices to it.
EXTRA COMMANDS
For stopping the hotspot we need to run,
netsh wlan stop hostednetwork
The hosted network stopped.
For disabling the hostednetwork,
netsh wlan set hostednetwork mode=disallow
The hosted network mode has been set to disallow.
