how to stop users(guests) from downloading and installing anything?

Answer 1

Put a password on your account and don't tell it to them. Log off when you are not using it. Create a non-administrative account for them to use.

Answer 2

if they are using the Guest user, they shouldnt be able to I dont think however you could try this
Set there accounts so they do have administrative access...

Click start
Control Pannel
user accounts
Pick a task; Change an Accout
Click Guest
Change account type
and then choose Limited ....

Although I am not sure there is that option under guest but anywho.... any account that is set to limited is unable to install new programs! :)

I hope this helps

Answer 3

Theres a simple html script that diables right clicking, and there are other codes you could embed that run a pop-up script when you try to copy or download something off your page, but theres always ways around that stuff. Best way is to rewrite your page in javascript and instead of running html code for your page it runs a scriptlet, thus disabling all the simple functions like right clicking, as the page is rendered as an applet rather than a coded page. Otherwise, you could add code to your page to hide the path of the files on your website.
