Reset Brave Browser statistics (ads blocked, bandwidth saved) by editing the preferences JSON file.

Reset-BraveStats.ps1

<#
.SYNOPSIS
    Reset Brave Browser usage statistics such as bandwidth saved and ads blocked.

.DESCRIPTION
    This script reads Brave Browser’s preferences JSON file and resets user statistics (bandwidth and ad-block counters) to zero.
    It was created and tested on Windows 11 Pro 25H2 to fix corrupted or inflated Brave stats values.
    Brave must be completely closed before running this script, otherwise it will overwrite the changes upon exit.
    No administrative privileges are required.

.PARAMETER None
    No parameters required. The script runs interactively and confirms reset actions.

.EXAMPLE
    .\Reset-BraveStats.ps1
    Displays Brave statistics, asks for confirmation, resets values to zero, and verifies the update.
