On Monday, Microsoft employees bristled at comments from the press that users were unhappy with Windows Vista. With regard to User Account Control (UAC), Nash told reporters that "the process is the same in (Mac) OS X." He recounted how his wife recently bought a HP printer, and UAC had asked permission to install the driver. Being a second user on the system, she needed Nash's password to proceed. Nash said that he later installed the same printer driver on a Mac. "It asked the same question," he said. However, the Mac elevated the user's privileges across the board, while Windows only elevated the user's installation privileges.
On Tuesday, Microsoft provided figures from IDC predicting a strong adoption rate in 2007 for Windows Vista and the new Windows Server 2008 . IDC predicts that by the end of the year, 90 million copies of Windows Vista should be installed, and 35 million within the United States. By the end of 2008, that number is predicted to be 150 million worldwide, and 68 million within the U.S. That may be true, but an informal "over-the-survey" of WinHEC 2007 attendees showed most were still using Windows XP.
