This is a community-based project and is actively updated. This project aims at restoring the legacy Windows Update websites, and allows older operating systems (Windows 95, NT 4.0, 98, Me, 2000, and XP) to obtain updates like they used to.
Ever since 2011 when Microsoft pulled the plug on nearly all the Windows Update websites, the Windows Update feature for older Windows operating systems was no longer functional. The only way to install updates after that point was through external third-party installers which didn’t cover all the updates that the operating system would fully support. So, with this project, we can now update operating systems as old as Windows 95 all the way through Windows XP RTM like we used to back in the day.
IT’s still a work-in-progress, as sourcing the various update packages and installers is proving to be quite difficult in some cases, and not all versions of Windows/Microsoft Update have been recreated yet. However, as the ever awesome Michael MJD notes in his video overview of the project, it already works quite well for Windows 95 and Windows 98 and 98SE.
