Xbox Europe boss Chris Lewis has told GI that gamers have nothing to fear from Windows 7.
"Windows 7 will be great for games, undoubtedly," he said.
"It's all good news - it's even more robust, it's quicker relatively, and the early testing cycles are proving very promising overall.
"I think it'll be nothing but good news for PC gamers, but we'll have more to say on that later on this year."
Lewis also reaffirmed Microsoft's commitment to PC gaming overall, claiming that the Games For Windows campaign would be an ongoing investment.
