I’m still on Windows 7 – what should I do?

Support for Windows 7 has ended, leaving Marcy wondering how they can protect themselves

I do a lot of work on a Windows 7 desktop PC that is about five years old. I'm a widow and can't afford to run out and get a new PC at this time, or pay for Windows 10. If I do stay with Windows 7, what should I worry about, and how can I protect myself? I have been running Kaspersky Total Security for several years, which has worked well so far. Marcy

Microsoft Windows 7 - launched in 2009 - came to the end of its supported life on Tuesday. Despite Microsoft's repeated warnings to Windows 7 users, there may still be a couple of hundred million users, many of them in businesses. What should people do next?
