Argh! Why can't SONY write a well tested software for once! For last 2 months, the VAIO care update keeps failing (VPC-SC/SB models). Today it fails to install vaio care update. (from 6.3.x to 6.4.x). The Intel SATA registry patch keeps failing to install too. This incompetance on behalf on SONY is baffling to say the least!
