Right click of microsoft mouse not working?

Check the mouse settings if the right key is disabled if setting is alright than your mouse right hand side switch is faulty you can clean the switch by using cleaning spray called WD-40 or replace the switch if you have skill of soldering the switch cost less than a dollar or 10rupees. If you have soldering iron than you can replace it. But if you buy new soldering iron it will cost 100 to 200 Rupees or 4 dollars or instead of that buy a new mouse. Before that if you have a spare mouse than check that the spare mouse is working and if its working than you have to buy new mouse or if your spare mouse is not working than it may be the problem of the motherboard / Operating system anyone.
