Microsoft’s offer of a free upgrade to Windows 10 for users that are running Windows 7 or Windows 8.1 comes to an end Friday.
The offer applies to Home and Pro users -- Windows 10 Enterprise isn’t included. However, Microsoft previously has said it’s aiming to broaden access to Windows 10 Enterprise, which has additional security features, by offering it on a subscription basis.
Microsoft, Redmond, Wash., has listed Windows 10 Pro at $199 and Windows 10 Home at $119.
Meanwhile, a major update to Windows 10 -- dubbed the Anniversary Update -- is coming on Tuesday, Aug. 2.
Microsoft has disclosed planned enhancements to security, the Cortana virtual assistant and the Edge browser as part of the Anniversary Update.
David Barter, practice director for Microsoft technologies at Kittery, Maine-based GreenPages Technology Solutions, said he believes one of Microsoft's goals for Windows 10 is to eventually make it part of a software subscription package for businesses.
A subscription model for Windows could be especially relevant to businesses with 500 or fewer employees, which don't receive the discounts that come with licensing model offerings from Microsoft, he said.
Such businesses could potentially get both Windows 10 and Office 365 “for one low monthly payment of X, and never have to worry about an upgrade or hardware/OS support conflicts again,” Barter said.
