Windows only benefit is that it is GUI-user friendly. But, being descended from a primitive single-user architecture, it should still be considered unsuitable for server environments, especially web-servers. But that doesn't mean you need to format your C-drive and install linux. The advantage of linux is that it is very cheap on resources for server installations. You could get an old second-hand box for less than $100 without even a monitor, stick a screen on it temporarily while installing a non-gui linux that you can subsequently load up and maintain from your Windows box via putty or Exceed.
