Updated | Getuidx64 Require Administrator Privileges Better

//go:build windows

If you're writing software, ensure that you handle privileges carefully. For example, in C:

If you're asking administrator privileges might be required: getuidx64 require administrator privileges better

On macOS, the same technique works reliably even if the root account is not explicitly enabled. In containerized environments such as Docker, a process may run with geteuid() == 0 but be constrained by Linux capabilities or seccomp filters. That is acceptable for privilege detection: the system layer indeed treats the process as root, and any further restrictions come from higher‑level orchestration.

Even when geteuid() == 0 , you may still encounter permission failures. On Linux, file systems can be mounted with noexec , files can be locked with chattr +i , and SELinux or AppArmor policies can restrict actions despite effective UID 0. On Windows, UAC may be active, registry virtualization may redirect writes, or group policies may limit what even elevated processes can do. //go:build windows If you're writing software, ensure that

While not a standard Windows API, getuidx64 typically refers to a custom or utility function designed to retrieve extended user or process identifier information on 64-bit Windows systems. Common use cases include:

Administrator (or root) privileges are required for certain actions on a computer system to ensure security. Processes running with elevated privileges can perform operations that are restricted for normal users.

While running getuidx64 with administrator privileges may be necessary for its functionality, it's essential to be aware of the risks involved. Some of the potential risks include:
