Windows XP SP2 Activation 11

The Start menu received its first major overhaul in XP, switching to a two-column layout with the ability to list, pin, and display frequently used applications, recently opened documents, and the traditional cascading "All Programs" menu. The taskbar can now group windows opened by a single application into one taskbar button, with a popup menu listing the individual windows. The notification area also hides "inactive" icons by default. A "common tasks" list was added, and Windows Explorer's sidebar was updated to use a new task-based design with lists of common actions; the tasks displayed are contextually relevant to the type of content in a folder (e.g. a folder with music displays offers to play all the files in the folder, or burn them to a CD).[24]
A copy protection system known as Windows Product Activation was introduced with Windows XP and its server counterpart, Windows Server 2003. All Windows licenses must be tied to a unique ID generated using information from the computer hardware, transmitted either via the internet or a telephone hotline. If Windows is not activated within 30 days of installation, the OS will cease to function until it is activated. Windows also periodically verifies the hardware to check for changes. If significant hardware changes are detected, the activation is voided, and Windows must be re-activated.[32]
On release, Windows XP received critical acclaim. CNET described the operating system as being "worth the hype", considering the new interface to be "spiffier" and more intuitive than previous versions, but feeling that it may "annoy" experienced users with its "hand-holding". XP's expanded multimedia support and CD burning functionality were also noted, along with its streamlined networking tools. The performance improvements of XP in comparison to 2000 and Me were also praised, along with its increased number of built-in device drivers in comparison to 2000. The software compatibility tools were also praised, although it was noted that some programs, particularly older MS-DOS software, may not work correctly on XP because of its differing architecture. They panned Windows XP's new licensing model and product activation system, considering it to be a "slightly annoying roadblock", but acknowledged Microsoft's intent for the changes.[149] PC Magazine provided similar praise, although noting that a number of its online features were designed to promote Microsoft-owned services, and that aside from quicker boot times, XP's overall performance showed little difference over Windows 2000.[150] Windows XP's default theme, Luna, was criticized by some users for its childish look.[151][152]
A change has been made in COM to provide computer-wide access controls that govern access to all call, activation, or launch requests on the computer. The simplest way to think about these access controls is as an additional AccessCheck call that is done against a computer-wide access control list (ACL) on each call, activation, or launch of any COM server on the computer. If the AccessCheck fails, the call, activation, or launch request is denied. This is in addition to any AccessCheck that is run against the server-specific ACLs. In effect, it provides a minimum authorization standard that must be passed to access any COM server on the computer. There is a computer-wide ACL for launch permissions to cover activate and launch rights, and a computer-wide ACL for access permissions to cover call rights. These can be configured through the Component Services Microsoft Management Console (MMC).
COM infrastructure includes the RPCSS, a system service that runs during system startup and always runs after that. It manages activation of COM objects and the running object table and provides helper services to DCOM remoting. It exposes RPC interfaces that can be called remotely. Because some COM servers allow unauthenticated remote access, these interfaces can be called by anyone, including unauthenticated users. As a result, RPCSS can be attacked by malicious users on remote, unauthenticated computers.
By default, the Everyone group is granted local launch, local activation, and local access call permissions. This enables all local scenarios to work without modification to the software or the operating system.
If you implement a COM server and expect to support remote activation by a non-administrative COM client, then you should consider whether the risk associated with enabling this process is acceptable or if you should modify your implementation to not require remote activation by a non-administrative COM client or remote unauthenticated calls.
In the Launch and Activation Permissions area, you can control the local and remote permissions as well as the computer-wide limits and the defaults. You can specify both local and remote activation and launch permissions independently.
COM server applications have two types of permissions: launch permissions and access permissions. Launch permissions control authorization to start a COM server during COM activation if the server is not already running. These permissions are defined as security descriptors that are specified in registry settings. Access permissions control authorization to call a running COM server. These permissions are defined as security descriptors provided to the COM infrastructure through the CoInitializeSecurity API, or using registry settings. Both launch and access permissions allow or deny access based on principals, and make no distinction as to whether the caller is local to the server or remote.
COM activation is the act of getting a COM interface proxy on a client by calling CoCreateInstance or one of its variants. As a side effect of this activation process, sometimes a COM server must be started to fulfill the client's request. A launch permissions ACL asserts who is allowed to start a COM server. An access permissions ACL asserts who is allowed to activate a COM object or call that object once the COM server is already running.
The second change is that the call and activation rights are separated to reflect to two distinct operations and to move the activation right from the access permission ACL to the launch permission ACL. Because activation and launching are both related to acquiring an interface pointer, activation and launch access rights logically belong together in one ACL. And because you always specify launch permissions through configuration (as compared to access permissions, which are often specified programmatically), putting the activation rights in the launch permission ACL provides the administrator with control over activation.
A COM server application might expose itself to unauthenticated users to implement a COM callback scenario. In this scenario, the application must also expose its activation to unauthenticated users, which might not be desirable.
There are no backward-compatibility issues for call or launch rights. There is, however, an activation rights compatibility issue. If, in the existing security descriptors for a COM server, the configured launch permissions are more restrictive than the access permissions and are more restrictive than what is minimally required for client activation scenarios, then the launch permissions ACL must be modified to give the authorized clients the appropriate activation permissions.
For COM applications that use the default security settings, there are no compatibility issues. For applications that are dynamically started using COM activation, most have no compatibility issues, because the launch permissions must already include anyone who is able to activate an object. Otherwise, such applications generate activation failures even before applying Windows XP SP2 or Windows Server 2003 SP1, when callers without launch permission try to activate an object and the COM server is not already running.
The applications of most concern for compatibility issues are COM applications that are already started by some other mechanism, such as Windows Explorer, or Service Control Manager. You can also start these applications by a previous COM activation, which overrides the default access and launch permissions and specifies launch permissions that are more restrictive than the call permissions. For more details about addressing this compatibility issue, see "How do I resolve these issues?" in the next section.
If you implement a COM server and you override the default security settings, confirm that the application-specific launch permissions ACL grants activation permission to appropriate users. If it does not, you must change your application-specific launch permission ACL to give appropriate users activation rights so applications and Windows components that use DCOM do not fail. These application-specific launch permissions are stored in the registry.
