e.g. VAIO Control Center Update
Release Date 10/18/2013
Version 6.0.20.09270/6.0.19.09270/6.1.12.09270/6.2.11.09270/6.3.6.09270

This utility installs an updated version of the VAIO® Control Center software to add support for the Windows® 8.1 operating center and resolve an issue where the VAIO Event Service may not function after entering sleep mode, shutdown, or a restart of the computer will cause the brightness function to not operate properly.
worst so far is
if you let screen dim, it will not come back, have to hard reboot. VAIO Control Center update seem to fixed. (even it didn't show in control panel, programs as updated)
external display resolution seem to be wrong also. Doing 1080p mirror over Miracast, still said 720p
several device manager problems
