Same here when I went to Italy 2 years ago for honeymoon.
Learned a few words such as Grazie~, Prego~, Salute~

I know that the number of found registry "errors" is not the real measure for the quality of the "cleaner", but i am really surprised by the (low)numbers because i have deleted at least 3-4000 files and their folders.
Making a fair and comprehensive test/comparison would need a LOT of work, so this test i made is just a "first look" difference.

jv16 PowerTools is a Suite of useful Tools (i.e. a Toolbox)
that helps me trace and remove Software Remnants after Uninstalling Apps.

As far as for Registry Cleaning, I agree
it is Sneak-Oil when it comes to Most Registry Cleaners.
However, jv16 PowerTools is Not Just Another Registry Cleaner...
jv16 PowerTools is THE Registry Cleaner.

It's a long post, I didn't read all of it but I noticed quite a few comments saying not to use registry cleaners because they may damage the registry.
So, I'd like to mention that Tuneup Utilities backs up every change that it does (not only to the registry) so it's always possible to "go back in time" and reverse the changes.
In many years of constant use (since 2009 version) it never damaged anything on my computer and definitely made it much faster than it's normal state. It includes many other useful Tuneup features, also for the advanced user.
Definitely the most advanced Tuneup Software I tried, much better than Ccleaner for example (Ccleaner is way more primitive in it's features). Tuneup Utilities is not free but it gives the best value for money than any software I've ever used.
I just love it and recommend it to any computer!

Ccleaner is the best one to clean entire pc. Till the date it was working fine in my pc cleaning all the unnecessary data.

Cloud System Booster - New program from Anvisoft, it's worth trying.
Ccleaner - My first choice
Advanced SystemCare - good program
