Steps to Reduce Check Disk Scan Time Delay/Wait Time

Windows users must have experienced this problem one day or the other that due to improper shutdown of the computer they see a Check Disk scan next time they boot the computer. The screen shows the message

One of your disks needs to be checked for consistency. You may cancel the disk check, but it is strongly recommended that you continue

The scan is for the good purposes but what irritates me and others like me is that by default it takes 10 seconds to start the scanning process. So if you also want to reduce this time delay like me, then here is the small registry tweak.

Note: Take the backup of the registry before performing the following steps to undo any changes that you don’t like.


1.    Run Regedit.

2.    Navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager

3.    You don’t need to expand the Session Manager tree.

4.    On the right side, find a key named ‘AutoChkTimeOut’. If it isn’t there then we need to create one.

5.    Right click-> New-> Dword value and give it the same name AutoChkTimeOut.

6.    Double click the newly created key and give the time that you want in seconds.

Reboot is necessary. The chkdsk scan will use the new value from now on.

What I will advice you is to not to put time below 3 seconds as if you wished to cancel the scan then it would be difficult to cancel the scan. However you can scan your drives anytime by typing “chkdsk” in the run box.

Let me know if this helped you.
