I have a Sony Vaio laptop (PCG-K33), Windows XP sp3. I use Windows Media Player and Adobe Flash Player. Also use SonicStage for playing CDs (I like it best). Do I need to keep the VAIO Entertainment Platform, VAIO Media 3.1, VAIO Media Integrated Server 3.1, and VAIO Media Redistribution 3.1 in my computer? Or can I delete them? I really don't want to mess up the operating system, and am unsure whether or not to delete these programs. As it is, they are disabled and I don't use them (never have, so I don't know what they do). Thanks for advice.
