Latest Windows Service Packs and Updates

Microsoft regularly releases major updates to their Windows operating systems.

Traditionally those updates are service packs, but more often these days, they're semi-regular and significant updates via 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 via automatic patching.

Below you'll find all the latest information on both service packs and these other major updates that Microsoft is regularly pushing to its users.

As of June 2019, the last major update to Windows 10 is Windows 10 Version 1809, code-named Redstone 5. This update began rolling out on November 13, 2018.

Updating is completely automatic via Windows Update.

You can read more about the individual fixes and improvements on Microsoft's What's New in Windows 10 Version 1809.

As of June 2019, the latest major update for Windows 8 is Windows 8.1 Update.¹

If you've already updated to Windows 8.1, the easiest way to update to Windows 8.1 Update is via 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.

If you are not already running Windows 8.1, see How to Update to Windows 8.1 for detailed instructions on applying the Windows 8.1 update. When that's done, update to Windows 8.1 Update via Windows Update.

Microsoft is not planning another big update to Windows 8, like a Windows 8.2 or Windows 8.1 Update 2. New features, if available, will instead be pushed via updates on Patch Tuesday.

The most recent Windows 7 service pack is SP1, but a Convenience Rollup for Windows 7 SP1 (basically an otherwise-named Windows 7 SP2) is also available which installs all patches between the release of SP1 (February 22, 2011) through April 12, 2016.

The latest service packs for other versions of Microsoft Windows include Windows Vista SP2, Windows XP SP3, and Windows 2000 SP4.

In the table below are links that take you directly to the latest Microsoft Windows service packs and major updates for each operating system. These updates are free.

Please note that for most of you, the easiest way to install the latest Windows service pack or update is to run Windows Update.
