The registry is rather like your computer's 'central filing cabinet' or 'brain' if you will. Many savvy techs will advise you to leave your computer's registry, ALONE. The problem I have with Glary, and most all others of its kind, is (A.) the efficacy of all these 'fixers', and (B.) putting tools, so very invasive, in the hands of those who really don't have much experience. There is a 'Lite' or free version (which is perhaps missing some key attractions), and of course for a charge the 'Pro' or full version. Each of these 'fixes' has several more sub-options and 'fixes'. Glary Utilities is a software 'utility', bundling perhaps ten, or more, individual 'fix-it's' to improve your computer's performance - make it run like new! It will 'Optimize And Improve', fix your 'Privacy And Security', attend to your 'Files And Folders', get your 'System Tools' in order, and finally 'Clean Up And Repair'. This review focuses on Glary Utilities, but is, in fact, my opinion of all 'Fix-It-All' programs available. Let me start by framing the point that my 'opinions' are based on my experiences, thoughts/ideas shared by friends, and a good deal of research. Unless you're really into computer maintenance and Fix-It programs, you might want to sit this review out. This is a long one, sorry, but one I've been meaning to vent about this for some time.
