I wasn't the only person irritated by this. In the thread above, I notice you wrote:
"It isn't an issue of MS Office versus OpenOffice.org it's clearly a CCleaner issue that's been an issue for many long months of wiping out some MS Office settings which in my views those entries that remove the user settings for Word, etc., should be removed from CCleaner, the last time I checked my preferred Word, etc., settings weren't junk. To be blunt and to the point it pissed me off when I found out that CCleaner was the reason I had to constantly reconfigure Word 2003, hence the reason I disabled Office 2003 cleaning."
I assume you receive further information subsequently, but I don't think the developer has done all that he reasonably should to prevent such problems from arising.
If some people want or need such thorough cleaning that their settings have to be sacrificed in the process, I'm glad CCleaner provides this capability for them. But it isn't a behavior the user has any reason to expect. There must be a mechanism to bring the behavior to the user's attention before the effect is felt. One obvious way would be to turn Office cleaning OFF by default and pop-up a warning when the user checks Office. I still don't understand why the product cannot be programmed to distinguish settings from junk, but I tentatively assume there must be good reason for this. I also don't understand why CCleaner deletes a Word registry key when registry cleaning is turned of, only the temp remover is run, and the product indicates nothing was removed, and it seems this must be a serious bug.
At this point, the developer's irresponsible marketing of the product has destroyed the confidence in a product I need to allow it access to my registry, and I have deleted CCleaner.
