how can i increase security by limiting user account in windows xp home edition?

Multiple user account is a real threat to any system. By putting the multiple user account you are giving the permission to the multiple user to use their account in your system. So if you want to increase your security in your system than you can restrict the multiple user. Now how it is possible? By doing some changes in the account setting you can increase the security of your system so for that first of all open the control panel of your system. Now go to the user account. When you will click on that all the user account will be displayed their including the administrator. Now select the various user account and delete them. Now create a single account by the name of the guest. Give only some specific power to that account. Now set a password in your administrator account as well as the user account. Now after that when ever a user will log in to your account they can use only the guest account and cannot perform any type of cahnge4s in your computer.
