1. Disable your VPN software
VPN software can interfere with the Windows Update process sometimes. If you’re using a VPN connection to connect to a work network, disconnect from the network and turn off the VPN software (if applicable) and try upgrading again.
2. Rename your HOSTS file (temporarily)
If disabling your VPN software doesn’t work or if you don’t use a VPN, then try renaming the HOSTS file.
- Open the folder C:\Windows\System32\Drivers\Etc
- Rename the file named
HOSTS.OLD. You’ll be asked for consent (admin consent) to rename the file. Click Continue when prompted.
- Open a Command Prompt window and type the following command to clear the Windows DNS cache:
- Attempt to install Windows Updates again.
- Once done, rename
HOSTS. Also, inspect your HOSTS file and make sure you don’t block Microsoft Update server addresses.
3. Change your DNS resolver
Ad-blocking DNS servers like Pi-Hole can cause the error 0xc1900223 or similar. You’ll need to disable Pi-Hole temporarily to install Windows Updates.
If you’ve been using Pi-Hole at the router level, then you’ll need to revert to the ISP-default DNS resolvers, or use one of the free DNS servers (temporarily):
- Google Public DNS:
- And then, flush the Windows DNS cache by running the
ipconfig /flushdnscommand from a Command Prompt window.
