The new patch is now being delivered via Windows Update
Microsoft has recently started shipping a new update to Windows 8 and 8.1 computers in order to fix a recently-found Adobe Flash Player flaw that would expose users’ data if exploited successfully.Since Internet Explorer 10 and 11 both come with built-in Flash Player, Microsoft needs to manually update its browsers every time Adobe releases a new patch for its software, so KB2929825 is specifically designed to do this.
“Security issues have been identified that could allow an attacker to compromise a computer running Internet Explorer Flash Player for Windows 8.1 and gain control over it. You can help protect your computer by installing this update from Microsoft. After you install this item, you may have to restart your computer,” the patch description reads.
As said, the new patch is being delivered to Windows 8 and 8.1 computers via Windows Update, so no user input is required if this feature is enabled on your computer.
