Software sunset tracker
A selection of software whose end date has passed or is coming, with the dates from each vendor’s own page and what happens to your data. It is not every product: for everything Microsoft lists, see Microsoft’s “Ending Support in 2026” list. Upcoming dates come first. “Date passed” means the date on the vendor’s page is behind us; it does not mean we confirmed the shutdown.
Microsoft only, with a short explanation: Microsoft retirements 2026. Old Publisher files: start with Microsoft Publisher end of life or the list of our guides.
