Networking :: How To Reset Data Usage

In Settings > Network & Internet > Data Usage : data usage is monitored this day to one month back , this is entirely useless since usually people try to monitor their usage since last bill , windows 8.1 allowed resetting of counter in any specific day so the counter can report useful data you can use , through researching and an earlier post I got the understanding that this is the new vision of Microsoft of how Data Usage should work..

Now the question , for sure Data usage must be using some registry key to constantly store data usage per day to achieve this trick of collecting data use over a month , so resetting should be as easy as deleting that key and allowing it rebuild from that point forward , so what is the path to that key or went the extra mile and did the reg file to delete it ?
