This is a community-run resource to help you fix access to the internet and the Windows Update service on earlier versions of Windows.
Since Windows XP was discontinued in 2014, followed by Windows 7 in 2020, Microsoft’s support for their earlier OSes has significantly dwindled. As XP and earlier don’t officially support modern security improvements, such as the SHA256 hash algorithm required by modern SSL and Authenticode certificates as of 2019, much of the internet has become inaccessible to these devices. Adding insult to injury, Microsoft actively removed many downloads for XP and earlier versions in 2020. In effect, working with these OSes is now incredibly difficult.
Windows Update provides many optional and recommended updates, in addition to drivers for your system, but Windows XP and 2000 can only install critical security updates through the built-in Automatic Updates feature. Legacy Update revives the original Windows Update website - the only way to see and install every update available for your system.
Legacy Update can install all relevant updates necessary to fix access to the Windows Update service on Windows 8, Windows 7, and Windows Vista. These versions of Windows may display the error “Windows could not search for new updates: Windows Update encountered an unknown error” with error code 80072EFE, or may simply never finish checking for updates. Legacy Update identifies the updates your system lacks, and installs them automatically, restoring the Windows Update service to full functionality. This includes restoring access to Windows Ultimate Extras on Windows Vista.
Legacy Update also restores connectivity to many websites in Internet Explorer, and other programs that use the Windows built-in networking functionality. This includes Windows Product Activation on Windows XP and Windows Server 2003, allowing you to activate these versions of Windows online in seconds.

Huge thanks to Michael MJD for his demonstration video of Legacy Update!
The existence of this site shouldn’t be taken as an endorsement to continue using unsupported OSes. You should stick to a supported OS such as Windows 10 or 11 (or, try Linux?!). However, this service exists anyway in recognition that using these OSes is sometimes necessary to run legacy hardware/software, or just interesting to play around with.

Thanks to the Internet Archive for all they do to preserve information that might otherwise be lost forever. Their extensive Wayback Machine backups of the Windows Update website are what allowed me to successfully create Legacy Update.
Thanks to the countless people on MSFN, BetaArchive, and other Microsoft fan forums for all the little tidbits that helped me get this working.
A very special thank you to those who support me on GitHub Sponsors and Patreon, and to those who report bugs and help me discover fixes.
