Changing the CHKDSK countdown time

October 2016


When your system starts, CHKDSK automatically starts which will check your disk for errors. It sometimes asks you to press a key to bypass the checkdisk operation. A countdown will be displayed to skip disk checking by pressing a key which takes 10 seconds by default. This can be changed.


You will have to use these instructions to change the CHKDSK countdown time:
  • Click on Start > Run
  • Type regedit,
  • Locate:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\AutoChkTimeOut
  • Change the default value which is 10 sec, from 0 to 259,200 seconds (3 days).

Please note that with a timeout of zero, there will be no countdown to cancel the operation.
