#ENTER REGEDIT FIRST
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 *
