A Windows 7 message warns users of the end of security updates.

Many people are likely to see the opinion. Net Applications data suggested that Windows 7 accounted for nearly 40.2% of desktop use in February, a little more than Windows 10. When they listen to the message or not, this is a another story. Many of these people use either Windows 10-compatible computers or corporate computers where the operating system updates may be out of their control. Microsoft probably hopes the message will persuade at least some of these people to hide.

There is a strong motivation to make the leap, at least for companies and institutions. After the official support is complete, Microsoft only provides consistent security updates to companies that pay for extended support, which ends in 2023. It will make very rare exceptions in cases like the WannaCry ransomware outbreak. Although a Windows 10 upgrade does not necessarily guarantee protection against security threats, it will at least prevent attacks when solutions have existed for years.
