The Windows registry will allow you to hide computer drive letters. Each drive letter is assigned a power of $2$ based on its place in the alphabet. For example, to hide the k drive the 'NoDrives' entry would be assigned $1024.$ This is calculated by taking k$\text{'}$s place in the alphabet $($k is the $11$th letter$),$ subtracting $1(11-1=10)$ and using that value as the power of $2(210=1024).$ What number needs to be assigned to the NoDrives entry in the registry in order to hide the D drive $($assume the 'Decimal' radio button is checked meaning the number must be entered in base $10)?$
