Security researchers have discovered a large number of consumers are still using either unsupported or near end-of-life operating systems.
Kaspersky researchers told Silicon UK they had analysed the anonymised data of operating system use provided by Kaspersky Security Network users (with their consent).
It found that 41 percent of consumers still use unsupported and near end-of-life operating systems.
The Kaspersky survey found that while newer versions of Microsoft operating systems are available, older OS (such as Windows XP, Vista and Windows 7) are still in use by consumers and businesses.
It found that 40 percent of very small businesses (VSBs) and 48 percent of small, medium-sized businesses (SMBs) and enterprises still rely on older systems running at times ancient (in IT terms) operating systems.
Microsoft for example officially ended support for Windows 7 back in 2015, although security updates still continue.
