Question about cc cleaner

I have downloaded and ran cc cleaner for the first time. My computer is like, 5 years old. After it scanned, it came up with a list of literally hundreds, if not thousands of hits (or whatever they are called). I noticed a large portion ended with .dll and also included a lot of things with "uninstall" in the line.

My question is: am I supposed to remove (clean?) all of these items? It just seems like there are so many, I want to be sure before I remove things that I shouldn't.

 

Use these 4 to get them all. each finds stuff the other 3 miss.

Cleanup! http://www.majorgeeks.com/download4895.html
CrapCleaner, aka CCleaner http://www.majorgeeks.com/download.php?det=4191
EmpTemp http://www.majorgeeks.com/download.php?det=1575
and MRU_Blaster http://www.majorgeeks.com/MRU-Blaster_d4184.html

as a 4 pronged attack on stuff accumulated after every net session.

EmpTemp is not difficult to use, but certainly not as easy as CC or Cleanup!

It has to be done manually, as follows:
(1). It starts up showing the Temp Folders tab. If any programs are listed, just click on the lightning bolt and they will be removed.
(2). Next click on Cookies, History, URL tab and then on "show all" tab (far left icon on second row). Click on lightning bolt to remove all.
(3). Next click on "Find tmp files" tab. Click on appropriate Hard drive designation. I usually only click on C: as my others are for backup purposes. It will then check for all temp (tmp) files. It may take a while. If it lists any files, click on lightning bolt, far left one.
This will remove all tmp files (except 2 that cannot be removed).
(4). Then click on "Clipboard and Shortcuts" tab and then click on that is the far left one, in the centre group of 4. This will list all clipboards and shortcuts and then check to see of they are all valid and unbroken. If it finds any broken ones, click on the lightning bolt and they will be gone.
(5). Then close down program, click on X, top right of screen.
This takes longer to write about it, than it does to do.
But it is another arrow to your bow, in keeping your PC ticking over. Bazza.
