Windows XP Service Pack 1 (SP1) does not call a fatal stop error when Windows finds a corrupted registry entry. If you want to troubleshoot the cause of the registry corruption, you cannot collect the corrupted registry before Windows tries to fix it.

Windows XP SP1 contains a registry resiliency feature to automatically delete corrupted registry keys when Windows starts, and when a user hive is loaded when a user logs on or loads a hive with Registry Editor.
