I don’t think I remember ever seeing the Shared Utilities thing in my Programs section when I had my TR…
But if anything you could try uninstalling it in the Add/Remove Programs and then rebooting. Afterwards, use the VAIO Recovery Wizard and select Proceed With System Recovery > Custom Recovery > Application Recovery > (then select the Sony Shared Utilities Libary or whatever it is called)
You will have to reboot again and it will install it from the systems preinstalled application recovery system.
(Just checked that link above and you wouldn’t be able to it this way had to performed a clean install of XP.)
