Microsoft Office is the most popular office software suite around, and dates all the way back to 1990 when Word, Excel and PowerPoint were bundled together for the first time.

While the three remain the core Office applications, new ones have come and gone over the years with each new version.

And like any software, Office has an expiry date. In tech terms, that’s the date it’s no longer supported or updated by Microsoft.
