Is anyone still using Windows 7?

I use Windows 7 because themes and free Microsoft Office.

Office Starter 2010? I have that too, very useful.

That was only available on OEM Windows 7 that came with Office 2010 pre-installed by the OEM. On first opening MS Office you had the option of purchasing Office or using the free Office Starter (Excel and Word with a few restrictions - no macros for example).

I had Office Starter 2010 on a W7 laptop, it survived the upgrade to Windows 10 in 2015 and, after migrating the installed OS to a new machine, the upgrade to Windows 11.

No actual way your copy of Starter Office survived 2 major OS upgrades with the main functionality still intact.
