I use it to clear all my MRU (Most Recently Used) lists...When you open the program click on Settings & it will show you all the program lists & items it clears. If there are any that you don't want cleared uncheck that box.
Click on Scan & when it's done (it only takes a couple of seconds) then click on Show Results & it will list everything it will clear out. Then click on Clean Now & it clears them. It doesn't clean any cookies, only your MRU lists. I hope this helps.
MRU Blaster FAQ's:What is an MRU List?
MRU stands for "most recently used", however we use it to apply to any list or item that stores data such as the names and/or locations of files you have previously saved, opened, etc.Why should I delete them?
These lists can (and almost always) contain names and locations of files you have previously saved and/or opened with certain programs. By clearing your system, MRU-Blaster deletes these lists (it should be noted that this does not delete the actual files those MRU lists point to).
