With simply 58 updates to take care of this month, the December Patch Tuesday ought to make for a welcome  light-duty patch-and-test cycle. There have been no zero-days or experiences of publicly exploited safety points, although there’s a important replace to Microsoft Trade Server that ought to be a precedence. However we noticed much less strain on the Home windows, browser, and Workplace updates.

Microsoft has additionally launched two Servicestack Updates (SSUs) for its desktop and server platforms (ADV990001) and an replace to the Chromium venture (ADV200002).
