Microsoft Update

Microsoft Update is a feature in Windows Update that provides updates not only for Windows but also other Microsoft software (such as Microsoft 365).^[1]

History

Windows Update first became part of Windows with the launch of Windows 98. Since then, the Windows Update service has gone through many updates.

With the release of Windows Me, a feature called Automatic Updates was added, which allowed updates to be installed in the background.

In Windows Vista, Windows Server 2008 and Windows 7, instead of using the Windows Update website, users received updates through a built-in application.

With the release of Windows 10, Windows Update became more integrated with the operating system, introducing cumulative updates and mandatory security updates for some editions. As of 14th October 2025, Windows 10 will reach end of support, but see down below how to get extended security updates until 14th October 2026. And get support until 2031 if you upgrade (purchase) Windows 10 (Enterprise) LTSC 2021. It's a cut-down version of Windows 10, but will work just like it.

In Windows 11, Microsoft introduced smaller and faster update packages, alongside machine learning to optimize installation times.

In Windows Server 2025, Microsoft added a hotpatching option, allowing certain security updates to be installed without requiring a reboot.

Recent developments

In August 2025, Microsoft released update KB5063709 for Windows 10, enabling enrollment in the Extended Security Updates (ESU) program, which extends support until 14th October 2026.^[2]

Microsoft also began improving dark mode consistency across Windows 11, fixing long-standing issues in system dialog boxes such as file copy and delete prompts.^[3]

In the same month, Microsoft changed the Microsoft Store update system, removing the option to permanently disable automatic app updates. Users may now only pause updates for a maximum of five weeks, after which updates resume automatically.^[4]
