Microsoft users face a pressing challenge as the company rolls out its latest Patch Tuesday updates, addressing six actively exploited vulnerabilities among a total of 67 Common Vulnerabilities and Exposures (CVEs). The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has issued a warning urging users to update their systems by April 1st or consider turning off their devices entirely.
Active Exploits and Urgent Fixes
Trend Micro’s Zero Day Initiative has characterized the current landscape of exploited bugs as “extraordinary.” While the six zero-day vulnerabilities dominate headlines, they are accompanied by an array of other concerning issues. Microsoft’s comprehensive update encompasses 56 new CVEs across various platforms, including Windows, Office, Azure, .NET, and more. The inclusion of third-party CVEs brings the total to 67, highlighting the breadth of potential security risks.
The Register emphasizes the urgency of this update, noting that it features “a dirty dozen flaws” that demand immediate attention. Among these, six are rated as critical, with another six already being exploited by malicious actors. The severity of these vulnerabilities underscores the importance of timely security updates.
As we approach October, the significance of these updates is amplified by the fact that approximately 800 million users are still operating on Windows 10, which will cease receiving security updates after October 14, 2025. It is estimated that around 240 million of these users may not have the capability to upgrade to Windows 11 for free, while many others are expected to transition before the deadline.
Recent trends indicate a gradual shift, with Windows 10’s market share declining below 60% for the first time, as Windows 11 approaches a 40% share. Microsoft is reinforcing its stance on upgrades, clarifying that only fully licensed Windows 10 machines capable of supporting Windows 11 will be eligible for the transition. The company’s guidance highlights the imminent end of support for Windows 10, urging users to consider upgrading to ensure continued access to security fixes and technical assistance.
For those with Windows 10 devices that cannot be upgraded, the urgency to act cannot be overstated. The growing number of exploited vulnerabilities this year illustrates the heightened risk of leaving systems unprotected. Users may find it more prudent to invest in an upgrade rather than risk exposure to potential attacks. Dark Reading notes that the current number of Microsoft zero-days under attack is significant, marking this update as one of the company’s largest ever in terms of fixes provided.
As the deadline approaches, the conversation around the necessity of upgrading will likely intensify, particularly for those unable to afford new machines. The reality remains clear: proactive measures are essential to safeguard against the increasing threat landscape.
