I'm wondering how many of these programmes I can uninstall. I would like to keep the ones I obviously need, but am sure there is a lot of Vaio **** I don't need.
How about Google Earth; it is really hard to say. It is all depends on what do you need. Lot of those utilities are not really taking up much space. If you like to shorten the boot time, you may just disable the one that you don't need in your startup programs list.
I recommend use RevoUninstaller for uninstalling program or application you don't need it is a great program and it very useful it can even clean up the leftover files after uninstalled program and clean unnecessary or messed leftover file from your computer
