The Aberdeen boss was delighted as his side got back to winning ways after a run of six games without a victory.
Goals from Adam Rooney and Jonny Hayes earned a 2-0 success against Dundee United at Pittodrie ahead of the international break.
McInnes said: "It's nice to win. It's important for the players and supporters.
"We've had a few weekends of late where the players and staff have suffered the same as the supporters.
"It was good, the manner in which we did it. We didn't just turn up hoping to win, we controlled it from start to finish. Even though we didn't get the goal in the first half, the confidence of the team was clear.
"It's the kind of performance we've seen time and again over the past couple of years, and I applaud my players for the way they handled what could have been a difficult game.
"The supporters will be a bit more relaxed after seeing that performance today. It's only a start, but it gives us confidence in our level of performance."
The former Bristol City manager paid tribute to Hayes, who had a hand in Rooney's opener before getting on the scoresheet himself.
McInnes said: "Today we had far more players playing to their potential, and Jonny was one of those.
"He's been very single-minded over the last while, and even when we've not been winning games, he's been one who's put in a decent level of performance.
"He's brilliant to work with. He wants to add goals to his game, so I hope today was the first of many."
