If the update was a security patch and you choose to keep it rolled back, ensure you have other mitigations (e.g., a third-party antivirus, firewall rules) until Microsoft issues a corrected update.
Windows updates are essential for security, performance, and stability. However, occasionally, an update can cause problems: blue screens, broken drivers, application crashes, or network issues. When this happens, rolling back (uninstalling) the problematic update is often the fastest solution.
