I use CCleaner with Winapp2.ini downloaded periodically from the Piriform forums -http://forum.piriform.com/index.php?showtopic=32310&st=0- Which is what CCEnhancer does iirc.
CCleaner alone. Why? Because i´m afraid to erase something important (when working in other person computer), i think that the benefit doesn't pay for the risk.
CCleaner+ -http://heilnizar.deviantart.com/art/CCleaner-CCleaner-Winapp2-Updater-312311257 Updates both CCleaner and WinApp2.ini, to your location. Works like a charm. Though Norton (SONAR) may detect the Updater.exe in the Temp files and CCleaner+ will crash.
I use CCEnhancer with CC, although I think AlexC makes a valid point. Computer security always comes down to a matter of "who do you trust".
CCleaner alone. CCEnhancer only adds like 5 seconds to my startup of my CCleaner....nothing really useful it adds
Alone. CCleaner itself already has several areas it can optionally clean that could cause problems. CCEnhancer just adds even more.
I've used CCleaner with CCEnhancer in my desktop (Not laptop) for more than a year and i have not experienced any problems at all.
I just use CCleaner alone. I do not use CCleaner to clean any usage data - only temp files and browser cache (not cookies though), so this would be useless to me.
CCleaner alone, with manual review of winapp2.ini. I like to keep things as simple as possible when possible.
As for me - sometimes with CCEnhancer, sometimes without, but CCleaner is a must. Who knows are there any tests whether it worth to add the CCEnhancer?
Hmm, I've just voted and was surprised to see that I'm the first to vote. So the poll must be added just recently.
