This is a handy all-in-one utility, if you don't already have one you're happy with, or suspect you can do better.
Remember, it's free TODAY ONLY! You must download, install and activate (follow instructions in "readme") this before Midnight Pacific time!

As with all such programs, you should ALWAYS back up your registry before letting it delete anything, and just to be safe create a system restore point before running the program (but after installing/activating it).
Once you have taken these steps, it will be impossible for anything you do with the program to screw up your system irreparably -- so go ahead and tinker around! :)

Other good free all-in-ones include:
Glary Utilities
Advanced System Care (This is one that i have left running at all times, aka "at startup")
Toolwiz Care (Also worth having in startup, but not at the same time as ASC! Like AV programs,
you should NEVER have two all-in-ones running at the same time!)

Again, so long as you create a system restore point and backup the registry (both very easy to do, just ask if you need help) before running any of these programs, you won't even need to go through the Settings or Options and select what you want it to do or exclude/include (tho i personally still like to do this) -- anything it deletes erroneously or any other change it makes can be UNDONE.

Long as i've mentioned all of the above, i might as well add some other free programs i really like and install on most of the personal computers i work on (as many of you already know):
Utilities:
*Ccleaner, Defraggler, Recuva and Speccy (i run Ccleaner 2-3x/wk, Defraggler roughly every 5 days)
Process Explorer (far more useful and informative version of Task Manager)
Process Lasso (keep programs from using too much of your RAM and CPU)
WinDirStat (neat graphical representation of how much space all your files take up!)

AV & Anti-malware:
Avast! (let it autoupdate daily and scan weekly)
SpywareBlaster (update every week or 2 and let it do its thing, it uses NO system resources)
WinPatrol (requires some patience and practice initially, but well worth it)
SuperAntiSpyware (update and run every week or 2, depending upon your level of concern/paranoia)

Updaters:
FileHippo update checker (i run this once or twice a week)
SUMo (you may want to get the lite version, which i've not tried, to avoid their added junk)
I've tried and am still trying out a LOT of updaters, b/c none of them are close to perfect, and some of them just have very annoying user interfaces.

As with all free software, pay close attention when you are installing and be sure to disable any toolbars or additional programs (i.e. Relevant Knowledge) it suggests!

Of course, ALL these programs and MANY MORE can be downloaded from CNET. Most of them are also available from FileHippo, but for some reason its update checker fails to notice about 1/4 of my programs!
Many of them also have PORTABLE versions, which are sweet for a thumbdrive that you take with you to work on other people's PCs. ;)

If you are interested, i have LOTS of other free programs i use to varying degrees; i'd be happy to share those as well, just let me know what sorta stuff you're looking for (backup, cloud storage, duplicate file finders, partition, media players, photo editing, hardware info viewers, FF add-ons, etc.).

Sorry if any of this is old news to you, i've sent this to lots of people, mostly non-techie types. ;)
Also sorry if you are a Mac user . . . because most of these programs (and me) can't help you!

*if you love Ccleaner as much as i do, you will DEFINITELY want to expand its cleaning power manifold,
by downloading and running (it doesn't even need to be installed!) CCEnhancer!
