Microsoft Say goodbye to free upgrade of Windows 10

TIme to act fast to free upgrade your  PC/Laptop  to Windows 10 operating system, because last date for upgrading free Windows 10 on Windows machines is July 29, 2016, this date is approaching fast. That is the one-year anniversary of the release of Windows 10, which means the ability to upgrade to the new operating system for FREE will soon expire. (If you are interested, you can take a look at the official countdown here.)

In a January 21, 2015, Windows Experience blog post titled The next generation of Windows: Windows 10, we learned that Windows 10 would be a free upgrade. Author Terry Myerson said:

Today was a monumental day for us on the Windows team because we shared our desire to redefine the relationship we have with you—our customers. We announced that a free upgrade for Windows 10 will be made available to customers running Windows 7, Windows 8.1, and Windows Phone 8.1 who upgrade in the first year after launch.
A little over six months later, on July 28, 2015, Myerson penned another Windows Experience blog post, titled Windows 10 Free Upgrade Available in 190 Countries Today, in which he reiterated the free upgrade policy:

From the beginning, Windows 10 has been unique—built with feedback from five million Windows Insiders, delivered as a service with ongoing innovations and security updates, and offered as a free upgrade to genuine Windows 7, Windows 8.1 and Windows Phone 8.1 customers.
