It’s now less than a year until Windows 7 goes out of mainstream support; after January 14, 2020, Microsoft will no longer provide security updates or support for PCs running Windows 7 — unless you want to pay extra, of course.
This is a big issue for many companies: while Windows 7 is long in the tooth (it went on sale back in October 2009), it’s much loved — at least, as much as a PC operating system can be loved — and is still widely used.
Indeed, even though Windows 10 has been around since late 2015, it’s only in the last month or so that general usage of Windows 10 has finally overtaken Windows 7. According to Microsoft there are 1.5 billion devices running Windows, with more than 700 million running Windows 10. But that means there are hundreds of millions of devices running Windows 7, with that support deadline looming.
