JetClean has two main flaws that folks concerned about their privacy might not like. For starters, it considers an excessive quantity of cookies to be keepable, by default. It tries to install a toolbar, but you can refuse it throughout the installation process. Toolbars used to be an extremely

common add-on back in the Windows 98-XP era but it’s a very outdated concept these days.Another sore point about JetClean is the fact that JetClean doesn’t have a portable version. You must “create” one from within your computer’s installed version. At least the provision exists, and that should suffice for

some users.

Windows 10, Windows 8, Windows 7, Windows Vista, Windows XP, and Windows 2000 are all supported by the JetClean registry cleaning in both 32-bit and 64-bit versions.
