Windows XP was ‘insignificant,’ researchers say
According to data released today by Kaspersky Lab, roughly 98 percent of the computers affected by the ransomware were running some version of Windows 7, with less than one in a thousand running Windows XP. 2008 R2 Server clients were also hit hard, making up just over 1 percent of infections.
Windows 7 is still the most popular Windows operating system for schools and workplaces, and a lot of schools and workplaces are slower when it comes to updating Windows, and their security software like Firewall, Antivirus, Antimalware, and Antispyware programs.
Users who still use Windows XP are sometimes more likely to unplug their PC from the internet when they are doing offline tasks like Word Processing because Windows XP is no longer getting regular Security updates from Microsoft, and other software makers which stop supporting XP many years a go.
A lot of XP users know they should install many types of security software like Firewall, Antivirus, Antimalware, Antispyware, AntiRansomware, Virus Behavior Blockers, etc on their PC because Microsoft no longer release Security Updates for XP, and the XP version of Windows Defender/Security Essentials, Windows XP Firewall, and Internet Explorer. The Firewall which came with XP was not very good compared to Firewalls which came with paid antivirus programs, or free firewalls like Comodo Firewall which is more difficult to use, but is more powerful.
XP users using many types of Security software may of prevented WannaCry from infecting their XP computer if it is connected to the internet at the time.
