If you're experiencing technical issues, performing a manual by deleting the %appdata%\.minecraft folder (after backing up saves) is the most common community recommendation.
When users search for a "clean launcher," they are often looking for tools that offer:
: Using official or highly reputable open-source launchers to ensure the system remains "clean" of data-stealing software often found in some third-party "cracked" versions.
: This option deletes the "game" and "runtime" folders, including all their contents, directly from the working directory.
The official Minecraft Launcher includes a specific built-in function to help users maintain a "clean" environment without manually digging through folders.
