Windows 7

The biggest change to Windows 11 is its more stringent hardware requirements

Windows 7 is still running on tens of millions of machines around the world

As of February 17, all National Revenue Agency (NRA) e-services will not be accessible to users with Windows XP and older versions of browsers, the revenue agency recalled.

The company recommends for users to switch to Windows 10.

On January 14, exactly ten years after the launch of Windows 7, Microsoft stopped its technical support, according to a message on the company's website.

Microsoft Corporation announced that it will soon shut down the Windows 7 operating system.

The operating system will terminate its renewal on January 14, 2020.

As of April 17, Windows 7 users will receive a warning message. After the shutdown, the operating system will no longer be safe, as computers with this system will not have protection against current cyber threats.

Microsoft says its' new Windows 10 operating system is now running on more than 14 million computers, two days after the software was released as a free download.

That's a far cry from the company's goal of getting Windows 10 onto a billion devices within three years.

Microsoft on July 13 announced plans for a celebratory debut this month of Windows 10 operating software designed to spread the U.S. software titan's offerings across a broad range of devices.

The termination of support for the operating system Windows XP could pose security threats to the ATMs. 

A survey of CNN Money shows that 95% of world's ATMs still use this operating system. As of April 8 Microsoft stops the technical support for it, which means that there will be no security updates and the ATMs could become an easy target for hackers.
