[1] Tip: Obtain any driver updates your computer really needs from the device or computer manufacturer's download page only, NEVER via Windows Update (i.e., hide any driver updates offered via Windows Update or configure your system so that driver updates are never offered or installed via Windows Update).
[2] Yet another critical security update for Flash Player is to be released this week (i.e., today or later).
