Cheyenne Dunkley netted his first goal for Kidderminster as they beat boss Steve Burr's former club Macclesfield.
Dunkley headed the home side into the lead from Callum Gittings' corner shortly before half-time.
Ryan Rowe beat the offside trap and then finished coolly to make it 2-0 five minutes after the interval.
Substitute Marvin Johnson rounded off a convincing Harriers display with a low shot from the edge of the area that beat Silkmen keeper Lance Cronin.

Harriers manager Steve Burr told BBC Hereford and Worcester:
"I've got a lot of happy memories from my time there and it's a fantastic club.
"I enjoyed my time there but obviously today I was fully behind Kidderminster getting the win because we needed our first home win.
"I felt it has been coming and in the second half I thought we did particularly well and we finished off some good moves."
