    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management

    REG_DWORD Value Name: ClearPageFileAtShutdown (0 = Disabled clear / 1 = enabled clear)

    Or if you really meant prefetch...

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters

    DWORD Name: EnablePrefetcher (0 = Disabled / 1 = Application Launch Prefetch / 2 = Boot Prefetch / 3 = Prefetch All )

    There's no conclusive proof that clearing the prefetch speeds up your computer. On the contrary, it takes Windows extra time to repopulate the prefetch list if you delete it.

    On the other hand, as Thrax said, if you actually mean the pagefile, clearing it at shutdown isn't a perfomance enhancer, but a security measure. Old data, like passwords, can remain in the pagefile.
