Windows 7 extended support ends in exactly one year's time

[Allan]

Mainstream support for Windows 7 ended back in January 2015, but extended support, whereby Microsoft continues to deliver updates and fixes any vulnerabilities in the OS, runs for a further five years.   This will come to a halt on 14 January 2020, however, when Microsoft stops supporting the OS completely. This means no more bug-fixes, security patches or new functionality, making any user - personal or enterprise - significantly more susceptible to malware attacks.   If you're still using Windows 7, you're not alone. The latest figures from Netmarketshare showed that more than 36 per cent of PC owners are still clinging onto the venerable OS, being overtaken by Windows 10 - which claims 39.22 per cent - for the first time in December.    Things get worse when you look at the enterprise. According to Kollective, which is counting down to the death of Windows 7 on its website, as many as 43 per cent of enterprises are still running Microsoft's nine-year-old operating system.   The firm's research shows that, worse still, 17 per cent of IT departments didn't know when Microsoft's end of support deadline hit, while six per cent were aware of the date but hadn't yet started planning for their migration away from Windows 7.

It's higher than 38%...MS won't admit it

It's higher than 38%...MS won't admit it

Here is a post that goes along with what Patio said.

NetMarketShare reports on the state of the desktop operating system market on the first day of each month. In October, Windows 10 had edged closer to Windows 7, and I predicted that NetMarketShare would finally see Windows 10 emerge victorious in November.
It didn’t.
In fact, in November Windows 10 actually lost some usage share, dropping 0.14 percentage points. That puts it on 38.1 4 percent, down from the 38.28 percent high in October.

One can probably find Operating System usage statistics to support whatever their favourite OS is. Largely because they will all have some measure of sample bias.
