WINDOWS 10 users have been placed on alert, with those running a specific version of the market-leading OS having to update their PCs quickly or risk putting their machines in danger.

Microsoft has today put scores of Windows 10 users on alert, with those running an older build of the world’s most popular desktop OS needing to update ASAP. If you’re among the Windows 10 users who still haven’t updated from version 1903 (aka the Windows 10 May 2019 update) then you better do so fast as support for the patch will be ending soon. The Redmond-based tech giant has revealed that on December 8 the Windows 10 May 2019 update will be reaching its end of service.

This means Microsoft will stop providing technical support for the update from that date and will stop releasing bug fixes for newly discovered issues or security fixes for vulnerabilities.

So any Windows 10 users running version 1903 from that date risk opening their PCs up to a range of issues which could end up wreaking havoc on their machines.

Microsoft advises that anyone using software which reaches its end of service should upgrade as soon as possible to keep their PCs safe from attacks.

The news was revealed in an official post by Microsoft which said: “Your computer will still work, but it could become more vulnerable to security risks and viruses because you won’t receive new security updates or other quality updates.

“Microsoft offers complimentary support to ensure that your device has the latest updates installed and requires that your device be up to date before assisting with other technical support issues”.

Microsoft has said that support for all Windows 10 1903 editions will finish in December.

These editions are as follows: Windows 10 Home, version 1903, Windows 10 Pro version 1903, Windows 10 Pro Education version 1903, Windows 10 Pro for Workstations version 1903, Windows 10 Enterprise version 1903, Windows 10 Education version 1903, Windows 10 IoT Enterprise version 1903.

The Windows 10 makers added: “These editions will no longer receive security updates after December 8, 2020.

“Customers who contact Microsoft Support after this date will be directed to update their device to the latest version of Windows 10 to remain supported.”

If you’re running Windows 10 version 1903 right now and wish to upgrade then you can do so manually by selecting ‘check for updates’ via the Windows Update screen.

Upgrading to the latest version of Windows 10 not only brings with it the latest security fixes but the latest new features for the OS too.

And one of these potential new, inbound features was reported by earlier this week, with Microsoft testing enhanced video calling in Windows 10.

The hidden new feature, called Meet Now, was first spotted by Microsoft developer Rafael Rivera.

Rivera outlined how this feature works, with a shortcut button visible in the Windows 10 Taskbar which lets users quickly access a video call wherever they are in the OS.

Once this is clicked a window will then automatically appear asking you to ‘create a meeting’ or ‘join a meeting.’

Tapping the button will then instantly start a call via Skype. The feature has been in testing, with it unclear if or when Microsoft will roll out the functionality to the millions of Windows 10 users around the world.
