Disable diagnostic and usage telemetry

Overview​

About this script

This script improves your privacy on Windows.

These changes use Windows system commands to update your settings.

This script improves your privacy by blocking the transmission of diagnostic and usage telemetry data from your Windows device 1. This includes data about your device's usage, app compatibility, and system performance, which can be sensitive in nature. By stopping this data from being sent, you reduce the amount of personal information that could potentially be accessed by third parties.

The script works by configuring the Group Policy Object (GPO) and Local Policy preferences, which essentially govern your device's data sharing policies 2. These modifications restrict the data that Windows and its built-in apps can collect and send.

Upon executing this script, Desktop Analytics will be disabled, as it relies on basic diagnostic data to function 2. Desktop Analytics is a cloud-based service provided by Microsoft 4. It provides insights and intelligence for IT administrators 4. Desktop Analytics is deprecated and was retired on November 30, 2022.

Once this script is executed, even if the policy permits a telemetry setting of Security or Basic, users will not have the capability to opt for a higher data sharing level 3. This restriction is limited to the operating system and apps included with Windows, and does not pertain to third-party apps installed on your device 3.

This script uses Batch (batchfile) scripting language.

Safe for General Use

This script is recommended for all users. It helps to improve privacy without affecting stability.
