Understanding and Configuring User Account Control in Windows Vista. Enterprises today face a daunting task of enforcing desktop standardization. This challenge is intensified since the majority of users run as local administrators on their computers. As a local administrator, a user can install and uninstall applications and adjust system and security settings at will. As a result, IT departments often cannot gauge the holistic health and security of their environments.

Common tasks like browsing the Web and checking e- mail can become unsafe in this scenario. In addition, all of these elements increase an organization. For this reason, the Windows. User Account Control (UAC) was the outcome of this redesign process. A History of the Windows Administrator Account. By default, when Microsoft Windows. This account type enables users to install, update, and run software since an administrator account has system- wide access. When a user is added to the local administrators group, that user is automatically granted every Windows privilege. A privilege is an authorization attribute that affects computer- wide policies. For example, Se. Backup. Privilege allows a user to backup files and directories. Privileges should not be confused with permissions, though; permissions apply to objects while privileges apply only to user accounts. These privileges are collected and maintained in a user.

Windows 7 (asalnya dikenali dengan nama kod Blackcomb, dan kemudian Vienna) ialah versi terkini sistem pengendalian Microsoft Windows untuk kegunaan komputer peribadi, tak kira di rumah mahupun di pejabat, sama ada komputer. Hello, Noob (not really) here. I can’t even access Wusa.exe which I presume is because of the UAC setting is the highest. ON windows 7 and IFile Operation COM is hard for me. The access token also contains user specific data for authorization purposes; Windows uses access tokens to track what resources a user can access. Every Windows resource has an Access Control List (ACL), which is a list that records which users and services have permission to access the resource and what level of permission they have. Windows' authorization model uses the data contained within a user's access token to determine what access the user is permitted/denied in a resource's ACL. Administrative users automatically have. Read/Write/Execute permissions to all resources. All Windows privileges. While it may seem clear that all users should not be able to read, alter, and delete any Windows resource, many enterprise IT departments have no other option but to make all of their users administrators. The following are some reasons why enterprises run as administrator today: Application installation (members of the Users group cannot install or uninstall applications): Many enterprises have no centralized method for deploying applications to their users, such as Microsoft Systems Management Server. Enterprises that do utilize software deployment technologies allow users to run as administrator because of ad hoc application installations for specialized applications for specific departments (a custom spreadsheet application for the Marketing department, for instance). Custom Web applications (Active. X controls): With the growth of the independent software vendor (ISV) community, many companies are opting to have custom applications designed for their specific business requirements. Many of these custom applications include a Web browser front- end, which requires an Active. X control to be installed. Because Active. X controls are executable files and can contain malware, Windows prevents members of the Users group from installing them. Perceived lower TCO (reduced help desk calls versus reduced attack surface): Many enterprises believe that allowing users to install their own applications will help limit the number and cost of Help Desk calls. Unfortunately, running your enterprise workstations as administrator also makes your network vulnerable to . Malware can exploit a local administrator account. Ensuring that all users run as standard users is the primary way to help mitigate the impact of malware. A standard user account is a user account that has the least amount of user rights and privileges required to perform basic desktop tasks. However, while a standard user account does exist by default in Windows. Many applications also require users to be administrators by default, as they check group administrator group membership before running. No user security model existed for Windows 9. Windows 9. 8. As a result, application developers designed their applications assuming that they would be installed and run as an administrator. A user security model was created for Windows. In addition, a standard user on a Windows. As a result, most people continue to browse the Web and read e- mail as an administrator. Reducing the Total Cost of Ownership. Because UAC enables users to easily run as standard users, IT departments can have more confidence in the integrity of their environments, including system files, audit logs, and system- wide settings. In addition, administrators no longer need to devote large blocks of time to authorizing tasks on individual computers. This saves the IT staff time that can be redirected to overall system maintenance, reducing an organization. Furthermore, IT administrators gain better control over software licensing because they can ensure that only authorized applications are installed. As a result, they will no longer have to worry about unlicensed or malicious software endangering their network, causing system downtime and data loss, or creating licensing liabilities. In response to the challenges customers encounter when attempting to run as a standard user, Microsoft began researching how to make running as a standard user easier for everyone. Refining User Modes. In Windows. Standard users are equivalent to the standard user account in previous versions of Windows. Standard users have limited administrative privileges and user rights. However, standard users can perform these tasks if they are able to provide valid administrative credentials when prompted. With UAC enabled, members of the local Administrators group run with the same access token as standard users. Only when a member of the local Administrators group gives approval can a process use the administrator. This process is the basis of the principle of Admin Approval Mode. The following table details some of the tasks a standard user can perform and what tasks require elevation to an administrator account. Power Users also had write access to areas of the file system and registry that normally only allow administrator access. Power Users enabled some level of application compatibility; unfortunately, this did not address a fundamental problem: applications requiring unnecessary privileges and user rights. UAC does not leverage the Power Users group, and the permissions granted to the Power Users group on Windows. The Power Users group, however, is still available for backwards compatibility with other versions of Windows. To use the Power Users group on Windows. For example, modifying the system registry should always be an administrative task browsing the Internet should always be a standard user task. The UAC access token model makes this distinction even clearer. An administrator account in Admin Approval Mode is prompted for consent by the application or component that is requesting permission to use the user. UAC Architecture. While the Windows. The following illustration details how the logon process for an administrator differs from the logon process for a standard user. When an administrator logs on, the user is granted two access tokens: a full administrator access token and a . By default, when a member of the local Administrators group logs on, the administrative Windows privileges are disabled and elevated user rights are removed, resulting in the standard user access token. The standard user access token is then used to launch the desktop (Explorer. Explorer. exe is the parent process from which all other user- initiated processes inherit their access token. As a result, all applications run as a standard user by default unless a user provides consent or credentials to approve an application to use a full administrative access token. Contrasting with this process, when a standard user logs on, only a standard user access token is created. This standard user access token is then used to launch the desktop. A user that is a member of the Administrators group can now log in, browse the Web, and read e- mail while using a standard user access token. When the administrator needs to perform a task that requires the administrator access token, Windows. This prompt is called an elevation prompt, and its behavior can be configured in the Security Policy Editor (secpol. Group Policy. For information about how to adjust UAC Group Policy settings, see the . The one exception is the relationship that exists between parent and child processes. Child processes will inherit the user. Both the parent and child processes, however, must have the same integrity level. Windows. Integrity levels are measurements of trust. AIS facilitates launching such applications by creating a new process for the application with an administrative user. This is a new service for Windows. As a result, IT administrators will not need to replace the majority of pre- Windows. Virtualization ensures that even applications that are not UAC compliant will be compatible with Windows. When a non- UAC- compliant administrative application attempts to write to a protected directory, such as Program Files, UAC gives the application its own virtualized view of the resource it is attempting to change, using a copy- on- write strategy. The virtualized copy is maintained under the user's profile. As a result, a separate copy of the virtualized file is created for each user that runs the non- compliant application. The virtualization technology ensures that non- compliant applications will not silently fail to run or fail in a non- deterministic way. UAC also provides file and registry virtualization and logging by default for pre- Windows. Although virtualization allows the overwhelming majority of pre- Windows.
