Formerly, those updates pushed through comprehensive service packs, but more often these days, they're semi-regular and significant updates through Windows Update. In fact, in Windows 10 and Windows 8, the service pack, as we know it from previous versions of Windows, is essentially a dead idea. Much like updates on your smartphone, Microsoft is continually adding major features through automatic patching. Lifewire / Maritsa Patrinos Latest Major Updates to Windows 10 As of May 2021, the last major update to Windows 10 is Windows 10 Version 20H2, referred to as the Windows 10 October 2020 Update. This update began rolling out on October 20, 2020. Updating is automatic through Windows Update. You can read more about the individual fixes and improvements on Microsoft's What's New in Windows 10 Version 20H2. Latest Major Updates to Windows 8 As of May 2021, the latest major update for Windows 8 is the confusingly named Windows 8.1 Update. If you've already updated to Windows 8.1, the easiest way to update to Windows 8.1 Update is through Windows Update. See instructions for manually installing Windows 8.1 Update in the Download Windows 8.1 Update section of our Windows 8.1 Update Facts piece.
