2. Mandatory Integrity Control (MIC) Hardening on x64

While MIC exists on x86 as well, x64 Windows assigns stricter default integrity levels. A medium‑integrity process cannot open a handle to a high‑integrity process with PROCESS_QUERY_LIMITED_INFORMATION if that would reveal the high‑integrity user’s SID. The SeSecurityPrivilege is required, and that privilege is disabled in a filtered admin token. getuidx64 require administrator privileges exclusive
