Now you’re ready to
determine which type of control to use: share-level or user-level.
By default, Windows uses share-level, but if someone has switched your system to user-level, here’s how to switch it back. Double-click Network in the Control Panel to open the Network dialog box. Click the Access Control tab and then select the Share-Level Access Control radio button. Click OK, close all dialog boxes, and restart your computer so that the new settings will take effect.
After the computer is fired up again, you’re ready to assign share-level control to specific resources. Double-click the My Computer icon on the Desktop and right-click the resource (such as a folder or drive) to which you want to limit access. (You can also right-click a printer in the PRINTERS folder.) Choose Properties from the shortcut menu to display the Properties dialog box, then click the Sharing tab. Select the Shared As radio button and then designate how you want to limit control (for example, by making a folder Read-Only). Optionally, you can enter and confirm the password you’re assigning to the resource. When you finish, click OK and close all dialog boxes.
If the above options do not provide enough security for you, download Access manager for Windows.
Access manager provides much more security than standard ways in Windows.
