I have a handy wee utility on my home computer called CCleaner. It seems to keep my system running nice and smoothly as it wipes away the volumes of temporary files and clutter left behind by Word, Photoshop, Internet Explorer, Firefox and Windows itself. On days like these, I wish there was a utility that I could boot up in my head — to fix my registry and wipe away all of the crap. There’s stuff in here I’d love to run through secure delete, overwriting it with 35 passes to make sure it’s gone. But, alas, temporary files clog up my cache. For the human heart there is no remedy so easily administered.
