JetClean has an attractive interface with its functions separated into five collapsible menus: Registry Clean, Windows Clean, Apps Clean, Shortcuts Clean, and RAM Clean. Each of these menus contains check boxes allowing users to select and deselect which items they want the program to scan. The program took 2 or 3 minutes to scan our machine and turned up over 1,600 registry problems, which was impressive since we'd just tried another such program the day before that had claimed to repair our registry.
We appreciated the fact that JetClean has a tool in its settings menu that allowed us to create a system restore point before we went ahead with its offer to solve our problems. The program took a few more minutes to do its work of repairing our registry, deleting unneeded files, and otherwise cleaning things up. Our computer was no worse for wear after the fact, although users should always exercise caution when using these kinds of programs; though we had no problems, we can't promise that JetClean won't delete something that you actually need.
In addition to its cleaning features, JetClean also comes with several other tools, such as a system info display and an uninstaller; other features, including various boosters and optimizers, are available with a paid upgrade. Overall, we liked JetClean's straightforward interface and thorough scanning, and we think it's worth a try if your computer could use some decluttering.
JetClean installs politely but leaves a folder behind upon removal.
