Windows Update Restored gives support where Microsoft won't by providing updates to the operating systems you grew up with, including Windows 98, XP, and more.
Not everyone is running Windows 11 on their PC there are many who are not even running Windows 10. If you are one of a surprisingly large number of people still rocking an old version of Windows, you will be well aware that Windows Update no longer works.
It is probably not a bad guess to say that at least some Windows enthusiasts own some retro PC that still has Windows 95 or similar in it. If you wanted to update it, this website may help.
