Preface: this article refers to making direct edits to the Windows Registry. If you are not experienced with this subject, ask your company's IT Administrator or a computer-expert friend/neighbor for help. Our Tech Support group has seen a few reports of this error (Program not found - skipping AUTOCHECK) from customers when running Diskeeper's bootime defrag. The error starts early in the boot process while the Session Manager process (smss.exe) is busy getting the system up and running. Smss.exe is critical to loading the paging file, initializing the registry and loading kernel components. But, before it does any of that it looks to a registry key called BootExecute. At that location it launches any applications listed. Session Manager then looks to the Windows system32 folder for particular executables it has been instructed to launch. By default there is only one program listed here - autochk.exe, the boot-time version of chkdsk, which will run if there are any file system inconsistency flags detected (i.e. volume dirty bit is set).
