Title

File Explorer heap termination on corruption must be disabled.

Control

The default behavior is for File Explorer heap termination on corruption to be enabled. If it exists and is configured with a value of "1", this is a finding. Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SOFTWARE\Policies\Microsoft\Windows\Explorer\ Value Name: NoHeapTerminationOnCorruption Value Type: REG_DWORD Value: 0x00000000 (0) (or if the Value Name does not exist)

Discussion

Legacy plug-in applications may continue to function when a File Explorer session has become corrupt. Disabling this feature will prevent this.

Fix

The default behavior is for File Explorer heap termination on corruption to be enabled. To correct this, configure the policy value for Computer Configuration >> Administrative Templates >> Windows Components >> File Explorer >> "Turn off heap termination on corruption" to "Not Configured" or "Disabled".
