However, for my former Windows XP PC, it was the best registry tool (of a generally bad lot) I had tried. For uninstalling crapware, I use IOBit Uninstaller (free and works well, but installs a trial version of other IOBit software that must be uninstalled itself). I haven't used it on Windows 7, as I haven't seen the need.

I never contributed to that, given that I already had a lifetime license. I'm surprised to see a new version of this released, given all the comments on the Macecraft forum and elsewhere that complained about the company founder absconding to the far east with money given to take the product open source. To perform tune up by system cleaning, to fix system and registry errors please run proper analysis, contact technical support or visit Microsoft FixIt site that provides system repair patches for many different problems that will restore the damaged registry keys and errors to the original Windows settings without deleting or modifying any other values. It needs a brand new approach to system maintenance which meets the system requirements that this tool fails to deliver and will never do as the development was halted many years ago and the company is only interested in ripping off their costumers. Modern computing as well as new Windows systems and registry will not accept this old school cleaning and tune up softpack, it only causes damage. The last OS that JV16 somewhat worked with was Windows XP. They redesigned the icons in haste and are merchandizing the same old junk. Their open source project to loot their end users has failed, leastways that's what they stated as an excuse for abandoning the project after collecting a nice amount of money which has just disappeared after all.
