Slough were able to force a number of early corners against their play-off chasing near neighbours, but without troubling Brentford loanee Seb Brown in goal. Meddie Nsubuga, stretching for the ball, headed one effort high and wide
The first real chance of the game came the way of the visitors when a long ball over the top set Windsor top-scorer Michael Chennels free, but Lee Carroll was able to save well with his right leg. Soon after, Chennels should have done better with a free header in the middle after a corner was swung in, with his effort just a foot over the bar.
Slough entered the last third of the pitch only sporadically, and on one such occasion Abby Nsubuga got free on the right but was unable to pick out an amber shirt in the middle and Seb Brown gathered the ball.
There was a scare for the Rebels as Steve Daly slid in to challenge Ryan Parsons as he was charging into the penalty area. There looked to be contact, but referee Lee Collins waved away appeals and elected not to show Parsons a second yellow card for simulation, having been booked early on for a foul.
Another big chance came Windsorâ€™s way on 36 minutes, when some neat passing around the edge of the box ended with Chandiram slicing wide of the angle of post and bar when well-placed on the left.
Just before the interval, Chennels was allowed to turn and shoot after being played in, but Carroll was able to parry the ball away to safety.
In another rare attack, Danny Jeffreys got free on the right when the ball fell kindly after Davies had an attempt blocked. However the midfielder wastefully blazed high and wide when he had time to control the ball and direct his effort.
Windsor started the second half looking for an early goal, which almost arrived as Chennels was again put through on goal, only to be denied by Carrollâ€™s feet again.
Seb Brown was tested seriously for the first time soon after, with Slough restricted to a 30-yard effort from Jeffreys after Davies had seen a shot blocked.
The game was beginning to open up a bit more, with Slough venturing forward via the creativity of Pritchard in the midfield. However Davies cut a lone figure in attack, with Sloughâ€™s advances soon breaking down as the disciplined Royalists back four snuffed out attacks with ease.
The introduction of nippy winger Ben Porter in place of Chandiram gave the visitors new impetus, and twenty minutes after his arrival, Windsor took the lead. Porter was able to whip in a cross from the left which was headed into the bottom corner of the goal by Matt Seedel, leaving Carroll wrong-footed and the visitors a goal ahead.
Windsor really should have extended their lead soon after, as Steve Butler powered a free header wide from a corner.
Another big chance arrived when Chris Robinson lost possession and allowed Porter a clear run on goal, but Carroll again made a good save. Porter was denied again soon after, this time by a post, after Terry O'Connor crossed deep into the box.
Late substitutions by Slough could do nothing to stop Windsor, with Tom Windsor and Jason Marney coming on, but having precious little time to have any impact. Instead Chennels found himself with yet another chance, but he flashed his shot across goal and wide when put through on the right.
As Windsor looked to run the clock down, the only attack Slough could muster was a long ball to Davies, who controlled and tried to cut inside, but Butler tackled him and cleared to safety to guarantee a deserved three points for his side.
