Given a choice, customers of a Pacific Northwest PC system builder overwhelming pick Windows 7 over the newer Windows 8, the company's president said Thursday. "Windows 7 is known, it has years of solid reputation behind it, but Windows 8 has gotten a mixed reaction in the press and social media, and the lack of a Start menu is a hot-button issue among our customers," said Jon Bach, president of Puget Systems, an Auburn, Wash. independent PC builder.
