If you imagine guests using your laptop or tablet during their visit, you might want to clean them up. For computers, it's a good idea to create guest accounts, especially those without administrator privileges for the computer.
If you're still using Windows 7, you should change that. Until then, however, you can create a new account under Control Panel> User Accounts . Unfortunately, this feature is well hidden on Windows 10, and there seems to be no easy way to enable it.
However, you can create your own guest account with similar permissions. Click on the Start menu and enter lusrmgr.msc. Press Enter when the option is displayed. This will take you to the Local Users and Groups Manager. In the sidebar, click the Users folder, right-click an empty area in the middle area, and choose New User. "Visitor" or similar) and deactivate the check box User must change password at next logon. Next, check the User can not change password and Password never expires check box and close the window. Your new user should be displayed in the list.
Right-click on your new user, select Properties, click the Member Of tab, and remove it from the Users group. Click "Add", enter "Guests" in the "Object Name" box and click the "Check Names" button. Click OK, and then in the Properties window, click OK, and then close the Local User Manager. You should be able to log in as a new guest user without a password and without being able to disturb the system.
