Running Scandisk in Windows Me after improper shutdown

If Windows Me has experienced an improper/incorrect shutdown, then it will check the hard disk to correct any errors caused by the premature shutdown.

Instead of running the Scandisk in DOS realmode like in Win95/98, then in WinMe the Scandisk is launched after having booted to Windows. One can still disable the launch of Scandisk, but instead of AutoScan in the Msdos.sys, then it is a BINARY key in the registry:

[HKEY_LOCAL_MACHINE \System \CurrentControlSet \Control \FileSystem]
