MS Office memory hoggers
A typical installation of MS Office installs Find Fast, an indexing utility that loads at startup. This hogs system resources by regularly indexing the entire hard disk(s). You can improve performance of your computer by removing Find Fast from your StartUp folder. To reclaim the space used by the Find Fast index, open Control Panel > Find Fast, select your hard drive(s) and from the Index menu, click on Delete Index. When you've deleted your Index, click on Close and Stop from the Index menu.
Another item installed in the StartUp folder is named Microsoft Office. This does nothing apart from loading all MS Office libraries at startup to speed up launching of any Office applications. Since this is not necessary, you can delete this shortcut, too.
