The software typically receives two substantial upgrades every year from the Redmond-based firm.
Windows 10 recently received its first hefty update of this year – dubbed the May 2019 Update.
When new versions of Windows 10 are released, it is not compulsory that users download it immediately.
However, last month Microsoft declared it would soon begin a process of compulsory updates whereby users running the April 2018 version of Windows 10 would be upgrades to the new May 2019 version.
Now the American tech firm has confirmed it has begun this initiative ahead of November 12, 2019, the date in which the April 2018 Update will reach the end of its 18 months of service.
Microsoft has said it has started the compulsory update process for those running “Home and Pro editions” of Windows 10 and emphasised it is “critical to device security and ecosystem health”.
The tech powerhouse remarked: “We are initiating the Windows 10 May 2019 Update for customers with devices that are at or nearing end of service and have not yet updated their device.
“Keeping these devices both supported and receiving monthly updates is critical to device security and ecosystem health.
“Based on the large number of devices running the April 2018 Update, that will reach the end of 18 months of service on November 12, 2019, we are starting the update process now for Home and Pro editions to help ensure adequate time for a smooth update process.
“Our update rollout process takes into consideration the scale and complexity of the Windows 10 ecosystem, with the many hardware, software, and app configuration options users have, to provide a seamless update experience for all users.
“We closely monitor update feedback to allow us to prioritise those devices likely to have a good update experience and quickly put safeguards on other devices while we address known issues. Windows 10 Home and Pro edition users will have the ability to pause the update for up to 35 days so they can choose a convenient time.”
Microsoft also iterated the Windows 10 May 2019 Update is “available to any user who manually selects ‘check for updates’ via Windows Update”.
It is worth noting as and when Microsoft issues the May 2019 Update to a PC running the April 2018 Update, Windows 10 Home users will still be able to delay the installation of the new software by up to 35 days.
