Minimem Reduces the Memory Footprint of Unwieldy Applications

Windows only: Free application Minimem reduces the memory usage of individual running applications on demand. Similar pplications promising to make your computer run faster by freeing up RAM are a dime a dozen, and many of them aren't all they're promised to be. After giving Minimen a try on my PC and reading FreewareGenius's detailed review (along with the author's comments on that post), Minimem appears to be the real deal under the right circumstances. Minimem removes unnecessary memory pages from running processes you tell it to optimize. The program isn't the most useful for applications that already have great memory management of their own, but it seems to work well on many applications—both small and large—that have a larger footprint than they should.
