To prevent other users also issues in your Windows settings , it is best to use separate sessions . If you are a family team, each member of the family has its own session, if you are using the computer at work, close your session when you're not at your computer and protect your computer from "naughty" companions, and if you pay your computer open a guest session for that person. Unfortunately not always take these precautions, or we forget to log off and leave the team at the mercy of anyone. For these cases there are steps we can take, editing the local group policies can be defined many ways through which prevent changes to our Windows .
