Microsoft has set a firm date of October 31st for final sale of consumer Windows 7 machines, but business machines are another story. The official website has been updated as such to reflect this, with Microsoft noting that October 31, 2014 is the new end-of-sale date for Windows 7 Home Basic, Home Premium, or Ultimate PCs. Home Premium takes the cake when it comes to sales, but now Microsoft is pushing for Windows 8 to take over as reigning champ, per PC World.
Last year, Microsoft gave the same date for the halting of sale of all Windows 7 PCs, but then redacted that same announcement. It's standard practice to give a year's notice before pulling the plug on support, and this is projected to be the case with business machines, but it's possible this will change over the course of the year. Are you still using Windows 7 or have you updated? What about any business computers at the office?
