Louis van Gaal's side held on to secure three points against the Hammers, despite playing the second half with 10 men following Wayne Rooney's dismissal.
Having signed for the Red Devils at the start of the summer transfer window for £27 million, Shaw has been forced to endure an agonising wait for his first senior appearance for the club.
Nonetheless, the world's most expensive teenager made a steady start to life at Old Trafford, putting in a steady shift despite playing in an unfamiliar back-line.

Defensively he excelled, winning each of his three attempted tackles and 50% of his aerial duels. He also blocked two crosses on the left flank, while making five clearances and one interception.
He proved his confidence in possession, accumulating 66 touches in total, while playing 37 passes - 86% of which were accurate.
In total he completed one of two attempted dribbles and drew three fouls, the majority of which were suffered in his attempts to advance in the opposition half.
As we witnessed so often for Southampton last season, Shaw has no fear when it comes to assisting his side in the final third. He played one key pass and recorded two crosses with his efforts in this encounter.
Shaw gave a good account of himself before being replaced late in the match by fellow youngster Tom Thorpe.
