Legacy Update was already extremely useful if you chose to disembark from Microsoft’s upgrade railroad. Now it’s even more so.

Legacy Update has for years been a tremendously useful site and tool for those wanting to keep older versions of Windows alive and in active use. The site has updated its archive of files that Microsoft used to make available for free download in the official Download Center, but has in its finite wisdom removed.

We have mentioned Legacy Update a few times, such as when we wrote about running Windows XP in 2023 and how to keep Windows 7 running. It’s essentially an independent third-party recreation of Microsoft’s old Windows Update website, which just like the original analyzes your copy of Windows, finds what available updates (and Microsoft-supported device drivers) are applicable, downloads them, and installs them for you. The difference is that Legacy Update does this for old versions of Windows that Microsoft doesn’t support any more. You know, like Windows 10. Currently, this means:

A little further down the page, it adds:

The latest update earlier this month improves the Legacy Update Microsoft Download Center Archive. This is a collection of files that Microsoft formerly offered for Windows, brought together from multiple sources including the Archive Team’s MDC project, along with the Internet Archive.

Back in 2020, Microsoft suddenly removed all old SHA-1 signed files with only a few days’ warning.

• Window Maker Live 13.2 brings 32-bit life to Debian 13
• Classic MacOS for non-Apple PowerPC kit rediscovered
• Rebuilding VisiCorp’s Visi On UI reveals how Apple defined the GUI era
• Linux 6.18 crowned LTS kernel – and Alpine 3.23 wastes no time adopting it

For instance, if, like this vulture, you still favor Office 2003 – the last version with proper menus, rather than the wretched ribbon – here you can find the MS Office 2003 service packs: SP1, SP2, and SP3.

You can also find XP Mode here, the free add-on for Windows 7 to give it better backwards compatibility, which we wrote about back in 2014. The old Microsoft Virtual PC pre-Hyper-V hypervisor is here too. If you want to run XP Mode on other hypervisors, you might find the XP activation tool we covered in 2023 helpful to go with that.

For all that The Reg FOSS desk doesn’t use Windows much any more, sometimes we have to. Now two of our fleet of testbed machines have been blighted by Windows 11, which for us exceeds ME, Vista, and 8 as the single worst OS release to come out of Redmond. We are slowly converting our emergency spare Windows partitions to Windows 10 IoT LTSC, which has another seven years of updates in its future – but similarly veteran applications are also very handy. ®
