Mesut Ozil spearheaded a morale-boosting 3-0 win for the Gunners, their first in the league since February 11, with Theo Walcott and Olivier Giroud also getting on the scoresheet to help Arsenal leapfrog Manchester United and move up to fifth.
Fan protests calling for Wenger to go had gathered pace in recent weeks and the night started with a section of the club's support staying away until the 13th minute - 13 signifying the number of years since the Gunners last won the league - but it ended with fans staying behind the chant the Frenchman's name
"I'm happy when people are happy," Wenger said.
"And when you're at the club for such a long time and you really care about people who care about the club, you know how sad they are when it doesn't go well.
"So I can take care of myself because I am used to dealing with difficult periods but you want people who love the club to be happy, so I'm happy."
While Wenger was able to put questions over his future to one side for the time being, a fifth successive league defeat heaped more pressure on Hammers boss Slaven Bilic, and Saturday's fixture against 18th-placed Swansea has become a must-win
The Hammers now sit five points above the relegation zone and Bilic has insisted that his side must forget about their most recent defeat
"It is the key point for me to get that confidence back before Saturday," Bilic said.
"We need one win and it will change everything for us
Three points at this stage of the season are massive.
"We are looking over our shoulders, of course, and there is no point in hiding it
It's not being negative, it's being realistic.
"I told the guys 'okay, forget tonight, we have a few massive games in front of us'."
Bilic also confirmed that the reason behind Michail Antonio's half-time substitution was due to sickness he suffered hours before kick-off - but Bilic expects him to be fit for the weekend.
