Block Microsoft connectivity check hosts (breaks internet connection status, captive portals)

Overview

About this script

This script improves your privacy on Windows.

These changes use Windows system commands to update your settings.

This script prevents Windows from connecting to Microsoft connectivity check URLs.

This script enhances your privacy by blocking specific hosts that Microsoft uses to collect your IP address 1.

The blocked hosts are:

• msftncsi.com 2 3 4
• www.msftncsi.com 2 5 6 7 8
• dns.msftncsi.com 2 3 5 7 8 9 10
• ipv6.msftncsi.com 2 8
• msftconnecttest.com 2 3 4 9 11
• www.msftconnecttest.com 2 3 7 9 10 12
• ipv6.msftconnecttest.com 8 10 11

However, this script may cause several side effects:

• It disrupts captive portal (hotspot) detection 5 6 13.
• It impairs functionality of Microsoft software like Azure Backup MARS agent 14 and on-premises data gateway 15.
• A 'no internet' symbol may appear even when you are connected to the internet 2.

Carefully weigh the privacy benefits against potential functionality issues before applying this script.

Caution

This may lead to:

• Lack of immediate feedback on network status.
• Potential functionality issues in the system and applications that rely on NCSI for network information.
• Reduced ability of Windows and other components to determine internet connectivity.
• Windows and other software may incorrectly report that you're offline.
• Issues with automatically opening the sign-in page when a captive portal (hotspot) is detected.

This script uses Batch (batchfile) scripting language.

Not Advised

This script should only be used by advanced users. This script is not recommended for daily use as it breaks important functionality. Do not run it without having backups and system snapshots.

Implementation Details

• Language: batch

• Required Privileges: Administrator rights

• Compatibility: Windows only

• Reversibility: Can be undone using provided revert script
