For cleaning up the usual computer crud, CCLeaner works, and so does Empty
Temporary Folders 2.8.3, also free.
For cleaning up the same computer crud, MSAS doesn't work. If the MSAS
developers are pressed for resources, I'd suggest just deleting this
function, since so many other programs perform it so well. They could always
add it in a later release, although I wouldn't bother.
The problem I find is that this feature works sporadically thereby luring you
into a false sense of security. Generally it works, but when you NEED it to
work, when for example handing your laptop over to your boss, it fails. And
IE prompts your boss with www.jobs.com as a site you've been too
recently! Looks like it fails when IE is open and MSAS can't get write
permissions on the history file?
