England bowled out the tourists for 68 on Sunday morning to take a 1-0 lead in the two-match Investec series going into the second Test at Headingley, which starts on Friday.
And Root told Sky Sports: "The guys played exceptionally well over the week. That last day was really good so we are taking a lot of confidence from that into this week."
He added: "We want to win and we will definitely be going out there to do that. We want to prepare as best we can and hopefully we can get things right and start off well."
The Lord's clash was Root's first Test on English soil, an occasion he marked with scores of 40 and 71, and the Yorkshire batsman is delighted to have the opportunity to follow that up on his home ground - which has proved fertile for batsmen this season.
"It is amazing. It is great to have the opportunity to be here and I have loved every minute of it so far," he said.
"The wicket varies from game to game. This year quite a lot of runs have been scored on it so it will be interesting to see how it goes this week."
