A new method to update older versions of Windows, such as XP, Vista and 7, is now available.

Named ‘Legacy Update’, it is a modification which allows checking for updates on its website for XP users (similar to the original Windows Update site) and fixes checking for updates in the Control Panel on Windows Vista and 7. This works as of February, 2023.

Legacy Update is a free program, developed by many people, and is open-source on GitHub.
In my opinion, it is a great way to update older computers again, and it also works on Vaio UX (tested myself).

In addition to updating, it will also download the most recent Service Pack, which greatly reduces the time to update a freshly-installed copy of Windows.

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.
