Kevin Unangst, senior director for PC gaming in the Xbox group said that Games of Windows Live "wasn't the right approach". When he was asked if Microsoft is planning to use the Windows userbase to challenge Steam with the refreshed Windows 10 Store? He stated that "We are not intending to compete with Steam. If anything, we want Steam to be even more successful. They’ve done great things for PC gamers in terms of having a single store. Over time do we want more developers to come over to our store and offer it in addition to Steam? Absolutely. Is competition good for people? Absolutely. But our goal right now isn't to do anything else other than support Steam and help it run great on Windows 10."
