The leak can expose possible vulnerabilities in remaining Windows XP-based components in modern Windows versions. Windows XP has been discontinued by Microsoft in 2014, so it doesn't receive security updates these days. The leak can make it more vulnerable and extremely unsafe for daily use.

The Redmond software giant is currently investigating the leak incident.

      Watercolor was interesting. Unfortunately, it has disappeared in sands of time.

    We actually still run XP on one Laptop in the garage that is ‘off the grid’. We use it for automotive repair manuals (in pdf form) and to play music with it’s 20 year old 2.1 creative speaker system.

    Windows XP can do so much ! I’d love to see a XP machine running in my home with exFAT support.
