Microsoft is pushing out an unscheduled update Windows 10 to fix a "critical" security issue that was discovered this week Adobe Flash Player.
According to Adobe's support page, the company discovered a large number of security bugs in Flash "that could potentially allow an attacker to take control of the affected system." One of these security bug has already been reported as being exploited.
Because Windows 10 embeds Adobe Flash in its Microsoft Edge web browser, the company is pushing out the update on its own. The company is doing the same for Internet Explorer 11 for Windows 8.1, which also embeds Flash in the browser. All other versions of Windows need to manually download the latest version of Flash to get the security updates.
