What are the prerequisites and common methods to escalate from Administrator to SYSTEM privileges in Windows?

The prerequisite is having administrator privileges on the system. Common methods include creating a service using `sc`, `schtasks`, or `psexec`, exploiting MSIExec with custom `.msi` files, duplicating a SYSTEM token with tools like `incognito` or `Invoke-TokenManipulation`, or leveraging vulnerable drivers like `Capcom.sys`. Each method has specific OS compatibility and detection considerations. For more details, refer to Penetration Techniques - Switching from Admin Privileges to System Privileges.
