This is something that should be supplied with Windows...

Very well, thank you Piriform team. CCleaner is great!

I've always removed everything when I use the reg option. Never had a prob with it. Most of what it finds, I've either deleted or uninstalled anyway. Its a lot better / more reliable than most reg cleaning programs. Which wouldnt know whats what, and you'll probably end up screwing something up, or killing windows in the process

using registry cleaner=high risk

Not if you know what you are doing, and do not just delete everything that it shows without even viewing them.

Best cleaning software. Period.

Actually, it's not. While it is broad-spectrum, ie. cleans a lot, AFAIK it fails at cleaning Temps from other user profiles. What are you going to do with a machine that has tens even hundreds user profiles? (App called ATF-Cleaner did this several years ago already with XP and Vista, I wonder why CCleaner apparently still doesn't do it?)

Privacy: DiskMax now collects *anonymous* usage information that enables me to decide things like whether to discontinue support for Windows XP and whether to natively support foreign languages. I am making this a mandatory requirement since:
a) It is completely anonymous. The data is only considered in aggregate on top of that.
b) I have tried to gather this information through surveys before but very few of the total DiskMax user base participated.

That fact that this doesn't even give you an option to refuse this so called "anonymous" info makes me NOT install that product.

No software should effectivly "force" you to give over info, even if it is "anonoymous"

While that's true, it is a free application and I only chose that route since I couldn't collect it any other way. The information being collected includes only what operating system you are using (XP/Vista/7; 32-bit/64-bit), what language the system is using, what screen resolution (to see how big I can make the window for a future version to be), how much hard-disk space is being recovered over time (to measure effectiveness), cpu/ram (to see if I can include more cpu intensive steps, or make use of more memory to improve speed).

I have to know this information so that I can spend my time more effectively instead of guessing stuff and waiting for feedback to come in. I don't see how collecting any of that information is an invasion of anyone's privacy, particularly since there is full disclosure. I can see your point of view though and if you are willing to pay for a copy, I'd be more than happy to make a special copy for you that'll only work on your system. If not, accept that I think it is a fair compromise considering how much time and effort I put into making and supporting such an application for free.

You can head over to the facebook fan page to see how many people (nearly 8000) have absolutely no problem with it:
