=====
Been using CCleaner for several months now, and we think that CCleaner is getting better and better by every program update.
Cleaner is fast in use as long as you choose just to delete files, but if you choose the safe file deletion it takes much longer time, but this is normal as the files are overwritten several times. For normal users it is recommended to just using the normal deletions method, but if you want your temp files to really be deleted, then go ahead, use the secure file deletion.
The registry cleaner part of CCleaner is not the best registry cleaner out there, but it’s good enough for a normal Windows user. Remember that this piece of software is free! Available in 35 different languages.
Great tool to keep your system clean and tidy. Five Star
