Microsoft provides significant upgrades to its Windows operating systems on a regular basis.
Previously, the updates were sent by full service packs, but these days, they’re delivered via semi-regular and major updates via Windows Update.
In reality, starting with Windows 8, the service pack, as we know it from prior versions of Windows, is virtually obsolete. Microsoft, like smartphone upgrades, is constantly introducing key features via automated patching.
Latest Major Updates to Windows 11
As of May 2022, the most recent substantial update to Windows 11 is Windows 11 Version 21H2. Windows Update is in charge of automatic updates.
More information on the various fixes and enhancements may be found on Microsoft’s website Windows 11 Release Information page.
Latest Major Updates to Windows 10
As of May 2022, the most recent substantial update to Windows 10 is Windows 10 Version 21H2, commonly known as the Windows 10 November 2021 Update. Windows Update, as in Windows 11, does automatic updates.
More information on the various fixes and enhancements may be found on Microsoft’s website What’s New in Windows 10 Version 21H2 page.
Latest Major Updates to Windows 8
The most recent big update for Windows 8 is the perplexingly named Windows 8.1 Upgrade.
If you’ve already installed Windows 8.1, the quickest way to update to Windows 8.1 Update is through Windows Update.
Manual installation instructions for Windows 8.1 Update may be found in our Windows 8.1 Update Facts post under the Download Windows 8.1 Update section.
If you aren’t already running Windows 8.1, install the Windows 8.1 update by following the instructions in How to Update to Windows 8.1. Then, using Windows Upgrade, upgrade to Windows 8.1 Update.
Microsoft has no plans to issue another significant Windows 8 update, such as Windows 8.2 or Windows 8.1 Update 2. If new features become available, they will be distributed through Patch Tuesday updates.

The most recent Windows 7 service pack is SP1, however there is also a Convenience Rollup for Windows 7 SP1 (basically a rebranded Windows 7 SP2) that installs all fixes from the time SP1 was published (February 22, 2011) until April 12, 2016.
