In all my years as an IT Technician, the only times I ever come across system issues caused by bad or corrupted registary enteries is because the user has tampered with registry files and messed things up. Registry files, take up very little space on your drive and Windows will simply skip over any redundant or unreadable registry files it comes across. Attempting to fix corrupted registry files is something that should be done by an expert user with a sound knowledge of what they are doing. Programs such as this could potentially do more harm than good and in some instances will remove vital registary files.

The best registry cleaner is no registry cleaner. I can't think of a faster way to trash your system than to do deep registry cleaning.

Where do these come from? No one, who know a little bit about Windows, do not anymore believe registry myths.

But if you use this kind of software, please at least create system recovery point before "clean" your registry, to prevent the entire Windows installation go with the wash water in the drain.

There is no need to ever clean the registry. It is exceptionally rare for cleaning the registry to make a computer run faster or fix any other issues you are having, no matter how many hundreds or thousands of errors are found. If your computer is running much slower that it should, or you have some other issues with it, then in my exprience, around 99.9% of the time, a registry cleaner won't help.

Having said that, unlike Black Bird Registry Cleaner, which was a giveaway here a few days ago and just about every other registry cleaner, Auslogics Registry Cleaner is safe to use, as it won't delete any needed registry keys. So while, more than likely it won't make your computer run any better, at least it is highly unlikely it will case any issues.

It's worth noting that the Pro version was only released recently and has essentially the same functionality as free version previously had. Rather than adding features to the paid Pro version, they removed features from the free version.

I strongly advise against ever purchasing any Auslogics software, as they are not a trustworthy company.
