Title
File Explorer heap termination on corruption must be disabled. (Cat III impact)
Discussion
Legacy plug-in applications may continue to function when a File Explorer session has become corrupt. Disabling this feature will prevent this.
Check Content

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)
Fix Text
