Google reported to Microsoft a critical vulnerability in Windows 10, and publicly disclosed it ten days later.

After 7 days, per our published policy for actively exploited critical vulnerabilities, we are today disclosing the existence of a remaining critical vulnerability in Windows for which no advisory or fix has yet been released. This vulnerability is particularly serious because we know it is being actively exploited.

According to reports, the vulnerability requires Adobe Flash, and if you don't have Flash installed, or already have it patched, it should have mitigated against the vulnerability. Although the link in Windows 10 is still there, the update from Microsoft will finally close the door. As with any of these things, update to help avoid problems.

“We believe in coordinated vulnerability disclosure, and today’s disclosure by Google puts customers at potential risk,” a Microsoft spokesperson told VentureBeat. “Windows is the only platform with a customer commitment to investigate reported security issues and proactively update impacted devices as soon as possible. We recommend customers use Windows 10 and the Microsoft Edge browser for the best protection.”
