Data type Range Default value
REG_DWORD 0 | 1 1


Determines whether the system coordinates ("synchronizes") the running of startup scripts. When they are synchronized, the system waits for each script to complete before it starts the next script.

This entry stores the setting of the Run startup scripts asynchronously Group Policy. Group Policy adds this entry to the registry with a value of 0 when you enable the policy. If you disable this policy, Group Policy sets the value of this entry to 1. 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 1. (Please note that this is a reversal of the usual behavior.)

Value Meaning
0 The policy is enabled. Startup scripts cannot run until the previous script is finished running.
1 The policy is disabled or not configured. The system does not synchronize the running of startup scripts. As a result, startup scripts can run simultaneously.

Change method

To change the value of this entry, use Group Policy. This entry corresponds to the Run startup scripts asynchronously policy (Computer Configuration\Administrative Templates\System\Logon).

Note Image Note

This entry takes precedence over a user setting. When this entry appears in the registry, a policy is in effect, and the system ignores the value of RunStartupScriptSync in HKLM\SOFTWARE\Microsoft\CurrentVersion\Winlogon.
