KB5089573 forced install + Lenovo network stack degradation (HTTPS latency, build 26200.8524)
KB5089573 installed automatically on a Lenovo system despite updates being paused and no preview updates enabled. After installation, the system jumped to build 26200.8524 and the network stack degraded severely. Heavy HTTPS sites (LinkedIn, Google Finance, YouTube) take 20–60 seconds to load across all browsers. Speedtest is normal, other devices on the same network are unaffected, and both Edge and Chrome show identical latency. DISM shows no package for KB5089573 and the update cannot be uninstalled. Looking for correlation data from other Lenovo users.

Open Device Manager.
Expand Network Adapters.
Right-click your network device and select Update Driver.
Choose Search automatically for updated driver software and install any available updates.
Once removed, immediately go to Settings > Windows Update > Advanced options and toggle OFF "Get the latest updates as soon as they're available." Then pause updates for 7 days to block any automatic re-offer.
try system restore, it usually makes a restore point for windows updates
