As long as your network card has the ability to create a hotspot and you are running windows, it shouldn't be too hard.
Just head over to Settings, Network Settings, and there should be a tab for mobile hotspot. If there isn't, that means that either the version of windows that you are running doesn't support it or your network card doesn't support it. You should then be able to enable it and there you go, you have a hotspot from your laptop. Theres an edit button to change the SSID and password of the network if you choose to do so.
