Important: This section, procedure, or task includes tips which show you how you can change the registry. But, serious issues might happen in case you change the registry improperly. So, ensure that you follow these steps properly. For added protection, back up the registry prior to change it. Then, you can restore the registry if a problem occurs.
Go to 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 *
