Windows 10

**Windows 10** is a computer operating system by Microsoft. It is part of the Microsoft Windows group of operating systems. It was called **Threshold** when it was being developed (made/coded). Windows 10 was announced at a press event on 30 September 2014. It was released for personal computers on 29 July 2015. It is a free update for Windows 8 that can be found in the Windows Store until Windows 10 version 1709 was released.

Windows 10 is designed to provide the same look for different systems. These include desktop, laptop, and other systems. 

Unlike earlier versions of Windows, Windows 10 was regularly updated with new features based on user feedback, starting before it was first released. Each release has a four-digit build number. The first two digits (two numbers) refer to the year of release, and the other two digits refer to the month of release or the half of the year of release (e.g. "1903" refers to a build released in March 2019 and "21H2" refers to a build released in the second half of 2021).

All versions of Windows 10 are officially discontinued and do not get updated for free, and Windows 11 is the second most popular.

### Support lifecycle 
Windows 10 was originally released following Microsoft's fixed lifecycle policy, receiving mainstream support for five years after its original release, followed by five years of extended support. However, starting in February 2018 this was switched to the modern lifecycle policy (excluding LTSC), with each build receiving 18 or 30 (only for H2 versions) months of support after release, depending on edition. Furthermore, Home edition does not support the deferral of feature updates and will thus often receive a new version of Windows 10 prior to the end of the 18-month support period. This policy was first invoked in 2017 to block Intel Clover Trail devices from receiving the Creators Update, as Microsoft asserts that future updates "require additional hardware support to provide the best possible experience", and that Intel no longer provided support or drivers for the platform. Microsoft stated that these devices would no longer receive feature updates, but would still receive security updates through January 2023. 

Microsoft continued to support at least one standard Windows 10 release until October 14, 2025. While the company aimed to discontinue support for Windows 10 by October 2025, it announced an Extended Security Update (ESU) service in December 2023 for Windows 10 devices, until October 2028, for a yet to be announced annual pricing plan. Furthermore, unlike previous Windows ESU services, Windows 10 ESU will be available to individual consumers as well.
