| REG_DWORD | 0 | 1 | 0 |
Prevents users, including administrators, from installing programs from removable media.
This entry stores the setting of the Disable media source for any install Group Policy. Group Policy adds this entry to the registry with a value of 1 when you enable the policy. If you disable the policy, Group Policy sets the value to 0. If you set the policy to Not configured, Group Policy deletes the entry from the registry and the system behaves as though the value is 0.
| Value | Meaning |
|---|---|
| 0 (or not in registry) | The policy is disabled or not configured. Users can install programs from removable media when the installation is running in their own security context, but only system administrators can install programs from removable media when an installation is running with elevated system privileges. |
| 1 | The policy is enabled. Neither regular users nor system administrator can install programs from removable media, regardless of the security context. If a user tries to install a program from removable media, such as CD-ROMs, floppy disks, and DVDs, a message appears, stating that the feature cannot be found. |
To change the value of this entry, use Group Policy. This entry corresponds to the Disable media source for any install policy (User Configuration\Administrative Templates\Windows Components\Windows Installer).
