What does error code 0x800704CF mean?

Error code 0x800704CF appears when Windows can't reach Microsoft's activation servers. This is typically caused by network connection problems, VPNs, or proxy settings interfering with activation.

You may see a message like:

2. Check your internet connection

  • Confirm you're connected to the internet.

  • If you're using Wi-Fi, try switching to a wired connection or a different network.

3. Turn off VPNs or proxies

  • Disable any VPN or proxy services you're using.

  • These tools can block Windows from connecting to Microsoft’s activation servers.

4. Try activating while offline
