What is NCSI?

NCSI (Network Connectivity Status Indicator) is a Windows component that determines whether your device has internet access.

When Microsoft's probe endpoints are blocked by:

• ISPs
• DNS filtering
• Firewalls
• VPNs
• Corporate networks
• Country-wide restrictions

Windows may incorrectly display:

• No Internet
• Limited Connectivity
• Missing Wi-Fi features
• Microsoft Store issues
• Office activation problems

even though the internet is working.
