There are many computer tips and tricks and I am going to show you few of them in this article.
First tip is the way how you create invisible icons on desktop. Start the Policy Editor and than go to File_open_registry. Than select Local User, select Registration/Shells, select Hide all items on desktop.
By using this quality no one can open any site without your permission and no one can misuse your computer for this. First you have to open your internet explorer and go to Tools, than click on Content than, Content advisor and than click on the Enable, when next window is open click on General than go to Supervisor password.
Change the password here. It asks you for your old and new password.
In the same window there is tab named Approved Sites. Copy the links of sites you want block and than click on Never.
