A couple of weeks ago, Giveaway of the Day was giving the Pro version of Glary Utilities, and I installed it on every Windows install that I have (12). But I don't use that "one click" maintenance option, I use only what I need of the program, like repairing broken shortcuts, and finding/deleting empty unused, unneeded files & folders from previously installed software. Those tools are good.
I'm really not that crazy about these "all in one" utilities, but since it was free, I took it. One must use these types of software very carefully, not just blindly click to clean everything. If one's PC is running OK, don't break it. The same with a car, don't fix what isn't broken. I've seen this very program toast installs, especially the "registry defrag tool". And some users have reported having BSOD's after running it.
A long time ago, I checked their forum out, but after looking some of the posts over, I decided not to join. Many of these users were very PC illiterate, I felt that I could be of no help. I guess because I don't depend totally upon programs to maintain my PC, some things has to me manually done, such as driver updates.
