here we go...
there are some software that can perfom this task but i want to do
it manually using CMD command prompt :)
You just have to follow the steps given below and you will create your own hot spot network software in no time .
  USING  COMMAND PROMPT


Step 1 :    click on start menu and type " cmd " without quotes. Now  command prompt  will appear
               
 on start screen. Right click on cmd and select " RUN AS ADMINISTRATOR" .
          
Note :  It is must that you run cmd as administration   privilege otherwise it will show error in next steps.
  After clicking , computer will ask for permission select   "yes" then the command prompt screen will appear.

Step 2 :    NOW to check whether  your computer has drivers to support LAN or not, type" netsh wlan show drivers " without quotes .  It will show the output like the image.
 In the output Hosted network supported :Yes means that your compute supports hosted networks. Verify this.

 If the result is "YES"  then move further else download & install the latest wlan driver for your computer then continue.

Step 3 :  Type " cls " without quotes ,this will clear the screen .

Step 4 :   Now  to create the hotspot network  type following code in cmd  :
netsh wlan set hostednetwork mode=allow ssid=Hotspotname   key=password
                replace hotspotname with your desired ssid  and password with your password(at least 8 character) for the network and hit enter . for example we are creating our hosted network                  
like this :
netsh wlan set hostednetwork mode=allow ssid=nithak key=mywords

Now your hot spot network is created but currently it is offline.

Step 5 :  To start the Hot spot you just created type
                   netsh wlan start hostednetwork
                  and hit enter key

 Step 6 :  now you will find your hot spot in all wifi enabled devices near you computer(dependent range). connect to it by inputting you password chosen during creation and enjoy !! 
now you can close command prompt if you want.

Step 7 :    To check hot spot status type  following code  and hit enter                                                                           
netsh wlan show hostednetwork



 Step 8 :  To stop the Hot spot type following code and hit enter                                                          
netsh wlan stop hostednetwork

 Step 9 :  Again if you want to start hot spot just run cmd as administrator and type                         
                    netsh wlan start hostednetwork
       and hit enter . To stop repeat step 8.

 Step 10 : in case  you can't access Internet make sure your LAN connection is sharable if not do this :
    > > To share your Internet connection on this hotspot go to the Network and sharing center and click on Change adapter setting.

>>  Here right click on the Connection that you use to connect to Internet and select "properties".
            >>  In properties go to "Sharing" tab and check the box "Allow other network users to connect through this computer's Internet connection" and select the network connection name that is used by your hotspot.(For this check the Network Connection Window and look for Connection which says Microsoft Hosted Network Virtual Adapter). And save it. Now your Internet connection is shared. 

Step 11 :  that's all.. enjoy your own hot spot network without any software  easily.
