MRU-Blaster is a freeware utility that does just one thing: it scans your PC for your most recently used (MRU) files as well as cookies, browser caches, and other temporary repositories of potentially compromising information, displays them, and deletes them to your specification.
MRU-Blaster is a fairly powerful and comprehensive utility that can find and delete more than 30,000 files held by everything from Corel presentations to Google's toolbar history. It functions from the simple gray dialog that characterizes so many similar utilities: no frills, all business, and maximum efficiency and usefulness. You can add to its functionality with plug-ins, too. MRU-Blaster claims compatibility with all Windows versions from 98 to XP, but we tested it in Vista and it worked just fine.
There are several good reasons to use a utility like MRU-Blaster to do a simple task that Windows seems to handle well enough. One is that having a dedicated utility sometimes makes it easier to remember to do a job. Another reason is convenience; MRU-Blaster empties all your far-flung caches from a single program. But the best reason might well be that it does well what Windows "seems" to take care of. You don't have to Google far to turn up lots of evidence of built-in Windows features that don't quite do what they promise. If you're counting on Windows to safeguard your online privacy, you may be putting yourself at risk, and needlessly, given that there are free utilities like MRU-Blaster to hold up your end.
MRU-Blaster is a program made to do one large task - detect and clean MRU (most recently used) lists on your computer. These MRU lists contain information such as the names and/or locations of the last files you have accessed. They are located all over your registry, and for almost any file type. By looking at these MRU lists, someone could determine what files you opened/saved/looked at, what their file names were. (And, in many cases, the lists are displayed in drop-down menus automatically.) With additional plug-ins that allow you to clean out your Temporary Internet Files and Cookies, MRU-Blaster enhances the protection of your privacy.
