Win11PrivacyFix has 3 one-click settings -- the default turns off a handful of different data collection methods. The main window has a long list of options on the right side, each with an *i* icon that provides info when you hover the mouse cursor over it. I only tried the default plus a few added options, and for each disabled option Win11PrivacyFix just turned off that feature in the registry, e.g., turning a value from 1 to o. At the end of the list are a few options to tweak Windows appearance. EDY asked if one or more settings could effect Windows Update -- I can't see how, and saw nothing about this on the product page. That said, you can always check for an update when you know one's available, like after 1:00 PM Est on Patch Tuesday, and if it doesn't work, turn off whatever options in Win11PrivacyFix until it starts working, and you'll know what option not to use. Windows only updates once a month, with an optional update towards the end of the month.
Win11PrivacyFix adds the program's folder, plus a new folder in Users\ [UserName]\ AppData\ Local. It installs 1/2 dozen fonts, and adds an uninstall key to the registry.
