PC Security Tweaker is a security tweaking utility you can use to tweak Windows-based computers. It is compatible with all Windows versions and lets you control which users are allowed to access your PC and the level of access each user may have. You can choose to tweak access to lots of Control Panel applet functions, including Display, Network, Passwords, Printers, System, Add/Remove Programs, etc. You can enforce users to use separate system profile folders and provide them with their own custom shell folders such as Desktop, Start Menu, Favorites, My Documents.

Additionally, by tweaking, you can: disable selected Start Menu items, lock and protect disk drives in My Computer, disable the DOS and command prompt, interruption boot keys, real DOS mode, Registry editing, taskbar, task manager, and network access, hide desktop icons, and much more. You can password-protect Windows and restrict users to running specific applications only. Security tweaks can be applied universally or just to specific users. This software also lets you tweak Internet Explorer to secure web browsing.
