Windows - How to disable scan disk at Start up

In computers using Windows based operating systems, if there is an improper shut-down after a trouble shoot, then scandisk will start. To check the contents of the hard disk, scandisk will run when the computer is rebooted the next time. To disable scan disk at start up, it is imperative to disable the chkdsk command. For this, the registry editor must be run. With the help of the regedit command, the changes must be made. The computer must be restarted once the required modifications are made to save the changed settings. This process of disabling scan disk at start up can work only on Windows 2000 and XP.

Nearly every time Windows is not shut down properly, Scan Disk will run the next time you try to boot the machine.

chkdsk is a command that checks the disk surface for physical errors. To disable to chkdsk, you must run the Registry Editor (regedt32.exe)

In the Run tab type:

  • Under the HKEY_LOCAL_MACHINE subtree, expand to:
    • \SYSTEM\CurrentControlSet\Control\Session Manager
    • then change the BootExecute entry to:

autocheck autochk *
  • Finally exit the registry and restart your computer to save the changes
    • Note that this is applicable for Windows 2000 and Windows XP
