Memory optimisers are a waste of time and should never be used. Now for a tip that I found in one of my other forums which most of the experts here probably already know about and may have already been posted elsewhere. Open Taskmanager and leave it open. Open my computer,minimize and watch explorer's mem usage drop. Maximize and explorer will go to about half of it's original mem usage. Open a large word document and do the same.Winword.exe will dramatically drop it's memory usage,same as for IE. It even works with taskmanager.First opened it's using 3,780kb.Minimize then reopen and it's using only 1,432 kb. Works on quite a few apps I've tried. Funny thing is that if you use the keyboard shortcut to minimize - windows key+M - there is no drop in mem usage by any app.
