OpenVPN — TAP-Windows virtual network adapter
When blamed in a crash: Very likely the true cause
What to do
The classic virtual network adapter bundled with many VPN clients.
- Update your VPN client — it bundles the TAP driver.
- If you have several VPN clients installed, remove the unused ones; stacked TAP adapters conflict.
- Orphaned adapters: Device Manager → Network adapters → uninstall old 'TAP-Windows' entries.
