A new method to update older versions of Windows is now available.
Named ‘Legacy Update’, it is a modification which restores installing Windows updates on Windows 2000, XP, Vista, 7, 8 and 8.1. This has been confirmed working as of June, 2023.
Legacy Update is a free, open-source program, developed by kirb, with contributions from many people.
The way it works, is that it changes Windows Update and its ActiveX control to point to a different update server and update website. That server still has all the updates for older versions of Windows and supports the older encryption methods needed to download the updates.
In addition to updating, it will also download the most recent Service Pack and fixes some issues with Windows indefinitely searching for updates. This will greatly reduce the time and effort to update a newly installed copy of an old version of Windows.
In my opinion, it is the best way to update old computers as of 2023, and confirmed by my testing, it also works perfectly on the Vaio UX.
You can download the program for free from https://legacyupdate.net/. If you like it, consider giving a donation to the developers on their Patreon or Github sponsors page.
