Here you have 4 options. I will explain each a little. Computer Manufacturer is the settings chose by your computer makers you may not have this option on all computers.
Basically it will use your current default and allow access to all other programs. The Microsoft Windows option will default all programs to Microsoft programs.
Non-Microsoft will use any non-Microsoft application and remove access to the Microsoft version. The choice that we are concerned with is the final one: Custom. This configuration does not appear on all systems.
The LastUserInitiatedDefaultChange value has been added to the registry to assist applications in recognizing and respecting the user's default choices. This value is found under the following subkey. By adhering to such a scheme, the user's wishes are respected and their ultimate ownership of their systems is maintained.
In Windows XP and Windows Server , the list of applications displayed in the Change or Remove Programs tab under Add or Remove Programs can be filtered by the user to exclude entries for application updates. In these versions of Windows, this is accomplished through a Show updates check box at the top of the window. The Show updates option is not selected by default, so updates are not shown unless the user chooses to show them.
Changes to the check box state persist when Add or Remove Programs is closed; if a user chooses to show the updates, they continue to be shown until the user clears the check box.
It is always displayed regardless of the check box state. In Windows Vista and later, application updates are displayed on a separate page in Control Panel dedicated to updates alone.
This page is shown when the user clicks the View installed updates task link. There is no user-selectable option to show updates on the same page as installed programs. Despite the change in UI, the mechanism for registering as an update to an installed program remains the same as in earlier versions of Windows. Microsoft and non-Microsoft applications that use the Windows Installer do not need to do anything further for their updates to be recognized as updates.
Non-Microsoft applications that do not use Windows Installer must declare certain values in the registry as part of their installation to be recognized as an update to an existing program. The following example illustrates which registry values to declare for an installation to be recognized as an update to an existing program. The following example shows the pertinent registry entries for an update to the LitWare Deluxe application.
Non-Microsoft applications that do not supply the appropriate registry information, such as updates produced before this option was available, continue to be displayed normally in the list of installed programs and are not filtered out. Update filtering in operating system versions other than Windows Vista and Windows 7 is normally a user-controlled setting and should be respected as such by applications. However, in an enterprise environment, administrators can control whether users are given the option to filter updates through the DontGroupPatches registry value, as shown in the following example.
DontGroupPatches has no effect in Windows Vista and Windows 7, where the UI contains no check box and registered updates are always filtered. Policies are set only by administrators.
