Thanks guys for all your advice, I need it! I'm just creating 4 recovery disks using VAIO care, then I'm going to look into this further. So a clean installation disks requires on 3.1GB but I need 4 DVDs to create a recovery, what's that all about?
Anyway I uninstalled a few things first, BING and something else. Will proceeed with caution before uninstalling anything else, and might just settle for blocking programs from starting up.
