The effect of ransomware attacks on Microsoft’s older versions of Windows is starting to impact on Windows 10 with attacks such as WannaCry and Petrwrap being the most high profile.
Cybercriminals find older versions such as XP and Vista easy targets and have exploited vulnerabilities.
A study by Spiceworks revealed that two thirds of businesses had now moved over to Windows 10 to reduce the threat.
Speaking to ITPro, Peter Tsai, senior technology analyst at Spiceworks, said: “In recent months, widespread ransomware attacks such as WannaCry and Petrwrap have put businesses under pressure to upgrade unsupported operating systems, such as Windows XP and Vista, and move to more secure systems like Windows 10.
“And while Windows XP is still running in some businesses, it’s evident that more companies are beginning to recognise the security risks and prioritise upgrades in order to better secure their networks.”
The cyber-attacks that took place earlier this year affected users in more than 150 countries and highlighted the risk, especially with the much-loved Windows XP.
After the attacks, Microsoft warned all users to update their OS immediately to the latest version of the software.
A statement from Microsoft president and chief legal officer Brad Smith said: “As cybercriminals become more sophisticated, there is simply no way for customers to protect themselves against threats unless they update their systems.”
Mr Smith added: “We have seen vulnerabilities stored by the CIA show up on WikiLeaks, and now this vulnerability stolen from the NSA has affected customers around the world.
“An equivalent scenario with conventional weapons would be the US military having some of its Tomahawk missiles stolen.
“The governments of the world should treat this attack as a wake-up call.”
Microsoft has once again urged users to upgrade to Windows 10 if they haven’t already done so in order to receive the latest security updates.
