Hi PikaBrian,


Welcome to Microsoft Answers!



To disable automatic disk checking at Windows startup through registry, go to the following registry key:

Important: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

322756 How to back up and restore the registry in Windows:


HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager

In the right hand pane, double click BootExecute.

The default value of the key is autocheck autochk *

* means every drive is checked for consistency. Just add /K:C at the end before *. /K switch will disable autocheck on C: drive at Windows startup. So the final value should look like this:

autocheck autochk /k:C *

If you want to add more drives, the key should look like this: (disabling C and D drives)

autocheck autochk /k:C /k:D *

If you want to restore everything to default, just replace the key with the default one i.e.

autocheck autochk *
