COMClassStore

HKLM\SOFTWARE\Policies\Microsoft\Windows\App Management

Data type Range Default value
REG_DWORD 0 | 1 0

Description

Directs the system to search Active Directory for missing Component Object Model (COM) components that a program requires.

This entry stores the setting of the Download missing COM components Group Policy. Group Policy adds this entry to the registry with a value of 1 when you configure the Download missing COM components policy. If you disable the policy or set it to Not configured, Group Policy deletes the entry from the registry.

Value Meaning
0 (Not in registry) The policy is disabled or not configured. When a required COM component registration is missing, the program continues without it. As a result, the program might not perform all of its functions, or it might stop.
1 The policy is enabled. The system searches Active Directory for a missing COM component registration and if it is found, downloads it. The resulting searches might make some programs start or run slowly.

Many Windows programs, such as the Microsoft Management Console snap-ins, use the interfaces provided by the COM. These programs cannot perform all of their functions unless Windows 2000 has internally registered the required components.

Change method

To change the value of this entry, use Group Policy. This entry corresponds to the Download missing COM components policy (Computer Configuration\Administrative Templates\System).

Note Image Note

This entry can appear in both HKEY_LOCAL_MACHINE and HKEY_CURRENT_USER. If this entry appears in both subtrees, the value in HKEY_LOCAL_MACHINE takes precedence over the value in HKEY_CURRENT_USER.
