Registry Tweaks to Customize User Account Control (UAC) Options in Windows Vista and Later. There is a tutorial on this site for tweaking and customizing UAC (User Account Control) settings using secpol. Local Security Policy): But if you are a Home Basic or Home Premium version user and want to tweak UAC (User Account Control) settings using secpol. Group Policy Editor and its not included in Home editions of Windows OS. Don't worry, the same tweaks can also be applied using Windows Registry Editor, so you can also enjoy the UAC tweaks in Home editions of Windows Vista and later using registry editor. Type regedit in RUN or start menu search box and press Enter. It'll open Registry Editor. Now go to following key: 2. Under Policies key look for a key with the name . If its not present then create it by right- click on Policies key and select . ![]() User Account Control (Windows)A well designed User Account Control experience helps prevent unwanted system- wide changes in a way that is predictable and requires minimal effort. With User Account Control (UAC) fully enabled, interactive administrators normally run with least user privileges, but they can self- elevate to perform administrative tasks by giving explicit consent with the Consent UI. Such administrative tasks include installing software and drivers, changing system- wide settings, viewing or changing other user accounts, and running administrative tools. In their least- privileged state, administrators are referred to as Protected administrators. In their elevated state, they are referred to as Elevated administrators. By contrast, Standard users can't elevate by themselves, but they can ask an administrator to elevate them using the Credential UI. The Built- in Administrator account doesn't require elevation. The Consent UI, used to elevate Protected administrators to have administrative privileges. The Credential UI, used to elevate Standard users. UAC provides the following benefits: It reduces the number of programs that run with elevated privileges, therefore helping to prevent users from accidentally changing their system settings, and helping to prevent . When elevation is denied, malware is only able to affect the current user's data. Without elevation, malware can't make system- wide changes or affect other users. For managed environments, well designed UAC experiences allow users to be more productive when running as Standard users by removing unnecessary restrictions. It gives Standard users the ability to ask administrators to give them permission to perform administrative tasks within their current session. For home environments, it enables better parental control over system- wide changes, including what software is installed. Developers: For implementation information, see Redesign Your UI for UAC Compatibility. In Windows Vista, Protected administrators can choose to be notified about all system changes or none. The UAC default setting is to notify about all changes, no matter what their origin. When you're notified, your desktop will be dimmed, and you must either approve or deny the request in the UAC dialog box before you can do anything else on your computer. The dimming of your desktop is referred to as the secure desktop because other programs can't run while it's dimmed. ![]() The build in winvnc service is replaced by an external service. Vista require an isolation between the service and the desktop application. User Account Control (UAC) is a security technology Microsoft added to Windows starting with Windows Vista. It provides better security by displaying a dia. When you access a website, the computer will perform DNS caching, which means that the data in the form of domain name and IP address of the website that you access. What to Do with "The requested operation requires elevation" in Vista. Somehow you get the prompt The requested operation requires elevation sometimes when you try to. Fix the error "The requested operation requires elevation" in Windows 7 and Windows Vista. The error comes up when you run some specific commands in command. ![]() ![]() ![]() Windows 7 introduces two intermediate UAC settings for Protected administrators, in addition to the two from Windows Vista. The first is to notify users only when a program is making the change, so administrators are automatically elevated when they make a change themselves. This is the UAC default setting in Windows 7, and it also makes use of the secure desktop. The second intermediate setting in Windows 7 is the same as the first except that it doesn't use the secure desktop. Windows 7 introduces two intermediate UAC settings. Note: Guidelines related to writing code to support User Account Control are presented in a separate article. Design concepts. Goals. A well designed User Account Control experience has the following goals: Eliminate unnecessary elevation. Users should have to elevate only to perform tasks that require administrative privileges. All other tasks should be designed to eliminate the need for elevation. Often legacy software requires administrator privileges unnecessarily by writing to the HKLM or HKCR registry sections, or the Program Files or Windows System folders. Be predictable. Standard users need to know which tasks require an administrator to perform or cannot be performed at all in managed environments. Administrators need to know which tasks require elevation. If they can't predict the need for elevation accurately, they are more likely to give consent for administrative tasks when they shouldn't. Require minimal effort. Tasks that require administrative privileges should be designed to require a single elevation. Tasks that require multiple elevations quickly become tedious. Revert to least privileges. Once a task that requires administrative privileges is complete, the program should revert to the least privilege state. Elevation task flow. When a task requires elevation, it has the following steps: Entry point. Tasks that require immediate elevation when UAC is fully enabled have entry points marked with the UAC shield. In this case, users should expect to see an Elevation UI immediately after clicking such commands—and they should be extra cautious when they see Elevation UI from tasks that don't have a shield. In this example, the parental control and user accounts control panel items require elevation. When UAC is partially enabled or turned off completely, the UAC shield is still displayed to indicate that the task involves system- level changes and therefore requires elevation, even if the user might not see Elevation UI. Always displaying the UAC shield for tasks that require elevation keeps the UI simple and predictable. ![]() Elevation. For Protected Administrators, the task requests consent using the Consent UI. For Standard users, the task requests administrator credentials using the Credential UI. Separate elevated process. Internally, a new elevated process is created to perform the task. Revert to least privilege. If necessary, revert to least privilege to complete any steps that don't require elevation. Note that tasks don't . For example, if the user navigates back and forth over an elevation entry point in a wizard, the user must elevate each time. Usage patterns. User Account Control has several usage patterns (in order of preference): Work for Standard users. Design the feature for all users by limiting its scope to the current user. By limiting settings to the current user (as opposed to system- wide), you eliminate the need for an Elevation UI entirely, and enable users to complete the task. Incorrect: In this example, Windows XP users had to have administrative privileges to view or change the current time zone. Correct: In this example, the time zone feature was redesigned in Windows 7 and Windows Vista to work for all users. Have separate UI elements for Standard users and administrators. Clearly separate Standard user tasks from administrative tasks. Give all users access to useful read- only information. Clearly identify administrative tasks with the UAC shield. In this example, the System control panel item shows its state to all users, but changing the system- wide settings requires elevation. Allow Standard users to attempt task, and to elevate on failure. If Standard users can view the information and are able to make some changes without elevation, allow them to access the UI and have them elevate only if the task fails. This approach is suitable when Standard users have limited access, such as with properties of their own files in Windows Explorer. It is also suitable for settings on Control Panel hybrid hub pages. In this example, the user attempted to change program file properties but didn't have sufficient privileges. The user can elevate and try again. Work for administrators only. Use this approach only for administrator features and programs! If a feature is intended only for administrators (and has no navigation paths or useful read- only information for Standard users), you can prompt for administrator credentials at the entry point before showing any UI. Use this approach for lengthy wizards and page flows when all paths require administrative privileges. If the entire program is for administrators only, mark it to prompt for administrator credentials in order to launch. Windows displays such program icons with the UAC shield overlay. A well designed User Account Control experience helps prevent unwanted system-wide changes in a way that is predictable and requires minimal effort. ![]() ![]() In this example, the program requires administrative privileges to launch. Guidelines. UAC shield icon. Display controls with the UAC shield to indicate that the task requires immediate elevation when UAC is fully enabled, even if UAC isn't currently fully enabled. If all paths of a wizard and page flow require elevation, display the UAC shield at the task's entry point. Proper use of the UAC shield helps users predict when elevation is required. If your program supports multiple versions of Windows, display the UAC shield if at least one version requires elevation. How to Fix Windows 8, 8.1 and Windows 7 Language Bar Missing Issue. Method 1 (If you have done this already, go to method 2 straight away)-You can add the language. Root genius failed to install drivers? This article guides you through the process of how to install USB driver for your Android device, including the latest Android 6.0. Security Update for Microsoft.NET Framework 4 on Windows Server 2003, Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2. ![]() Because Windows XP never requires elevation, consider removing the UAC shields for Windows XP if you can do so consistently and without harming performance. Don't display the UAC shield for tasks that don't require elevation in most contexts. Because this approach will sometimes be misleading, the preferred approach is to use a properly shielded contextual command instead. Because the New folder command requires elevation only when used in system folders, it is displayed without a UAC shield. The UAC shield can be displayed on the following controls: Command buttons: A command button that requires immediate elevation. Command links: A command link that requires immediate elevation. Links: A link that requires immediate elevation. Menus: A drop- down menu that requires immediate elevation. Because tasks don't remember elevated states, don't change the UAC shield to reflect state. Display the UAC shield even if User Account Control has been turned off or the user is using the Built- in Administrator account. Consistently displaying the UAC shield is easier to program, and provides users with information about the nature of the task. Elevation. Whenever possible, design tasks to be performed by Standard users without elevation. Give all users access to useful read- only information. Elevate on a per task basis, not on a per setting basis. Don't mix Standard user settings with administrative settings in a single page or dialog box. ![]() For example, if Standard users can change some but not all settings, split those settings out as a separate UI surface. Incorrect: In this example, Standard user settings are incorrectly mixed with administrative settings.
