+ * - wininit.exe (rename operations left in wininit.ini - Win 9x only)
+ * - PendingRenameOperations (rename operations left in the registry - Win NT+ only)
+ *
+ * Startup (before the user logs in)
+ * - Services (NT, ?semi-synchronous?, not implemented yet)
+ * - HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServicesOnce (9x, asynch)
