3. Select the device that you want to wake the system, and then double-click to open the Properties dialog box. 4. On the Power Management tab, click Allow this device to bring the computer out of standby. If no Power Management tab appears, the device does not support system wake.

You can prevent users from configuring power options by specifying Control Panel settings in Group Policy. You can disable Control Panel entirely, hide specific Control Panel tools, and show specific Control Panel options. Hiding Power Options can be beneficial if you have configured the power options and you do not want users to change those options. However, if you hide Power Options, users have no means to reconfigure power management settings if they need to be changed while they are away from the office. For example, portable computer users frequently use the Portable/Laptop power scheme. When they use the portable computer for a presentation, however, it is recommended that they switch to the Presentation scheme to prevent the portable computer from turning off the display or entering standby or hibernation during the presentation. Users cannot change power schemes or any other power option if Power Options is not available. To hide Power Options by using Group Policy settings 1. In the Run dialog box, type gpedit.msc. 2. In the Group Policy console tree, under User Configuration, open Administrative Templates. 3. Click the Control Panel folder. 4. In the details pane, double-click Hide specified control panel applets. 5. In the Hide specified Control Panel applets Properties dialog box, click Enabled, and then click Show. 6. Click Add. 7. Type either the name of the Control Panel utility (power options) or its associated .cpl file (powercfg.cpl). Typically, Power Options appears in the Show Contents dialog box, under List of disallowed control panel applets. To disable Control Panel by using Group Policy settings 1. In the Run dialog box, type gpedit.msc. 2. In the Group Policy console tree, under User Configuration, open the Administrative Templates folder.

3. Click the Control Panel folder. 4. In the details pane, double-click Prohibit access to the Control Panel. 5. Click Enabled.

A user profile is a group of settings and files that defines the environment that the system loads when a user logs on. A user profile contains:

A portion of the registry that stores registry settings such as Windows Explorer settings, persistent network connections, taskbar settings, network printer connections, userdefined Control Panel and Accessories settings, and application settings. A set of profile folders that store information such as shortcut links, desktop icons, and startup applications.

User profiles are located by default on the local computer; one profile is created for each user who has logged on to that computer. When administrators configure profiles to roam, the data and settings in a user s profile are copied to a network server when the user logs off of the computer. The data and settings are then available to the user no matter where he or she next logs on to the network. While useful for mobile users, roaming user profiles are also beneficial for users who always use the same computer. Roaming user profiles provide a transparent way for such users to back up their profiles to a network server, thus protecting the information from individual system failure. If a user s primary workstation needs to be replaced, the new computer receives the user s profile from the server as soon as the user logs on. You can use roaming user profiles together with Remote OS Installation and Software Installation and Maintenance when you replace a computer. If a computer system fails and loses its data, you can use Remote OS Installation to install Windows XP Professional, use Software Installation and Maintenance to restore applications, and use roaming user profiles to restore critical information. Because a network copy of the data exists, you can easily reestablish links to critical information.
