NIS 2013 Network Drives Scan turned off?

Hi,

 

This is enabled by default with in NIS 2013. Both of my machines though are running NIS 2013. One of them is Windows 7 64 bit and the other Windows 8 64 bit. Is it okay to disable the network drives scan option with in NIS 2013? I would imagine its not needed in my case correct for either machine?
