A second half penalty from Alfie Pavey, the Havant & Waterlooville striker, proved to be the difference.
The Three Lions were in control of the first half at Leyton Orient but failed to turn possession into clear cut chances.
They did just after the break. Ed Williams, the in-form Kidderminster midfielder, nearly broke the deadline minutes after the teams returned.
His brother Harry was a hero at the World Cup and just after the hour mark Laurence Maguire played a key part in the winning goal.
Hauled over in the box, he won a penalty midway through the second half.
Hawks strike Pavey found the top corner to make it 1-0 and it could have been more after that.
But in the end one goal was enough as Fairclough’s side full of the National League’s best English talent held firm.
