True.But you still had to know what you are doing and what and what to look for.
I have used it for many years & I usually know what I'm doing from years of using computers.
The inexperienced can really mess things up.
That's why I say to all to use Macrium or something similar to be safe in case they mess anything up.
For manual registry work I used "RegSupreme pro" instead of Regedit, until it license expired. It had advantage of finding, listing and editing of multiple entries at same time. Now I'm using: Download Resplendent Registrar Registry Manager Lite - MajorGeeks to overcome shortcomings in Regedit.
When you say you run benchmarks and after using Ccleaner the system doesn't run any faster. Those benchmarks look at overall computer performance. But they don't test speeds within a browser. I notice faster page loading and faster browser response after using Ccleaner. The browser is not searching through 2gb of files looking for a cached item to load instead of getting a fresh one. It gets to a point where getting a fresh item from the internet is faster then looking through the 2gb of junk.
Just because Windows has a built in function doesn't mean it's better than using a different program. Do you use a different word processor (like MS Word) instead Windows built in Wordpad? Why, Windows already has that word processor function built in, why would you use a different one?
Not everyone has SSD and most have fast internet. We have a fiber optic connection to the house. I use Ccleaner because I notice the difference within the browser. If I didn't notice the difference I wouldn't bother using it.
Your HDD isn't sitting there picking up one file, looking at it, saying "Nope, not it" and tossing it back onto the pile before moving onto the next file. Even if it was, we're talking about a process that takes an average of 8ms.
I don't even know where to begin setting this strawman on fire. Unless we're talking about secure deletes, which would be kind of pointless if we're dealing with temp files of one form or another, deleting a file is deleting a file, the end. There's no difference between using the "del" command from the command prompt, Windows Explorer, or CCleaner. Each and every one of them makes the same API call to the kernel which then takes care of it because user level programs like CCleaner are prohibited from directly accessing the hardware on a protected mode OS like Windows.Just because Windows has a built in function doesn't mean it's better than using a different program.

Then you're comparing two completely different programs which just happen to share some common functionality. WordPad is a surprisingly competent little program and one of the true gems of Windows that most people aren't even aware of. However, to say that it is on the same scale as Word, is laughable on its face. WordPad may well be perfectly suited to the needs of a great many people, who do not need the full expanse of Word's features, but it's like comparing a Ford Pinto to a Ferrari and saying that they're the same thing because they're both cars. Or maybe a slightly less hyperbolic comparison might be to compare the base model Prius with the fully loaded luxury model. You've got a California flag, so let's put it this way: Something like traction control might be a lot more useful if you live in higher elevation areas like Tahoe compared to places that rarely see anything other than clear skies and sun like SD, LA, or the SF Bay Area. Does everyone need traction control? No. Does that mean it doesn't have a great deal of utility to a certain subset of drivers? Not even close.
Also, the speed of your internet connection really means jack all when it comes to how fast files may download. You can have a direct connection to a backbone, won't mean dick if the server on the other end is overloaded. Plus, very few people, the world over, have a fast Internet connection and even fewer have fiber like you. The US in particular lags way behind the rest of the industrialized world on that front with a great many people still on dialup. Broadband in the US is defined as 4Mbps downstream thanks to all the lobbying efforts on the part of companies like AT&T and Comcast. If they could push it lower, they would. I would also personally say that more people are likely to have a SSD than they are a fiber connection to their home.
You can write 20 pages of fluff if you want too, but what am I suppose to believe, you or my eyes?
