I would add CCleaner to that list. Sped my computer up quite a bit after installing and running (CCleaner also includes a registry cleaner which is safe to run as it’s not too aggressive, like many registry cleaners).

Best of all - it’s free and has won numerous awards. I’ve used it since probably 2002 or 2003 with zero trouble.
Done. Thanks for the tip.
