Temporarily disable or restrict the Cross Device Service if feasible until a patch is available. 6. Monitor Microsoft security advisories closely and apply official patches immediately upon release. 7. Use least privilege principles to limit local user rights and prevent low-privileged users from writing to system directories. 8. Conduct regular audits of writable directories and DLL files to identify unauthorized changes. 9. Implement network segmentation to limit the impact of compromised endpoints. 10. Prepare incident response plans specifically addressing privilege escalation scenarios.
