Recently I took delivery of a Microsoft Band in order to improve my fitness and lose weight and so far so good! I'll probably do a more in depth write up when I have had a chance to really get to know the device.
You can alter the devices settings through the associated app on your phone, but they don't seem to have publicised the Windows app. Interestingly this is a desktop download rather than a "modern" app, but I think is a pre-cursor to Windows 10 apps being universal.
You can download the app at https://www.microsoft.com/en-us/download/details.aspx?id=44579
