Adds the Run in Separate Memory Space check box to Run dialog box. This check box lets users run a 16-bit program in a dedicated (not shared) Virtual DOS Machine (VDM) process. The additional check box is enabled only when a user types the name of a 16-bit program in the Run dialog box.
This entry stores the setting of the Add "Run in Separate Memory Space" check box to Run dialog box 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 or set it 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. TheRun in Separate Memory Space check box does not appear. |
| 1 | The policy is enabled. The Run in Separate Memory Space check box appears on the Run dialog box. |
All DOS and 16-bit programs run on Windows 2000 in the Windows Virtual DOS Machine program. VDM simulates a 16-bit environment, complete with the DLLs required by 16-bit programs. By default, all 16-bit programs run as threads in a single, shared VDM process. As such, they share the memory space allocated to the VDM process and cannot run simultaneously.
To change the value of this entry, use Group Policy. This entry corresponds to the Add "Run in Separate Memory Space" check box to Run dialog box policy (User Configuration\AdministrativeTemplates\Start Menu & Taskbar).
