According to a recent study conducted by Lansweeper, the security landscape for Windows 10 users is increasingly precarious. The findings reveal that PCs running Windows 10 are burdened with an alarming average of 1,903 active security vulnerabilities. In stark contrast, systems upgraded to Windows 11 boast a significantly lower vulnerability count of just 652, which is roughly one-third of what Windows 10 users face.
Security Risks and User Adoption
This disparity highlights the critical need for users to consider upgrading to Windows 11, particularly from a security standpoint. Despite this pressing recommendation, data from Statcounter indicates that nearly 20% of Windows PCs in the United States remain on Windows 10 as of June 2026. This reluctance to transition comes at a time when Microsoft has ceased regular updates for Windows 10, leaving users reliant on the limited security patches provided through the Extended Security Updates (ESU) program.
Security experts have been vocal about the urgency of upgrading. As early as January 2025, warnings were issued against delaying the switch to Windows 11. With each passing month, the vulnerabilities associated with Windows 10 are expected to increase, further amplifying the risks for users who choose to remain on the outdated platform.
For those who opt to continue using Windows 10, it is advisable to enroll in the free ESU program, which provides access to the latest security updates until October 12, 2027. This interim solution may offer some peace of mind, but it is not a substitute for the comprehensive security enhancements available in Windows 11.
However, not all voices are in favor of the transition to Windows 11. Some data privacy experts caution against making the switch, advocating for users—especially businesses and organizations—to remain with Windows 10 for as long as feasible. This perspective underscores the complex considerations that users must weigh when deciding on their operating system.
