If you’ve been procrastinating taking the plunge to windows 10, now’s the time to do it…
Should you need a Windows 10 upgrade after the December 31st cutoff, you’ll probably have to pay for it. A license for the Home edition starts at about $75 for a system builder OEM copy that is tied to a specific PC. Retail copies with less restrictive licensing are a bit more expensive, as is the professional version of the operating system.
