Getuidx64 Require Administrator Privileges Better Jun 2026

For developers: isolate the privileged part of getuidx64 into a COM object running in a high-integrity surrogate process. Call it from a non-admin client via CoCreateInstance with CLSCTX_LOCAL_SERVER . This keeps your main application non-elevated.

uid_t safe_getuid(void) HANDLE hToken; if (!OpenProcessToken(GetCurrentProcess(), TOKEN_QUERY, &hToken)) return -1; DWORD tokenUserSize = 0; GetTokenInformation(hToken, TokenUser, NULL, 0, &tokenUserSize); TOKEN_USER* tokenUser = (TOKEN_USER*)malloc(tokenUserSize); if (!GetTokenInformation(hToken, TokenUser, tokenUser, tokenUserSize, &tokenUserSize)) free(tokenUser); CloseHandle(hToken); return -1;

The answer lies in . Windows does not have a direct 1:1 mapping of Unix UIDs. Instead, it uses Security Identifiers (SIDs). A function like getuidx64 is almost certainly:

The file getuidx64.exe is the 64-bit deployment engine and driver installer for CPU-Z. When you launch CPU-Z, it relies on this executable to extract, install, and communicate with its low-level hardware monitoring driver ( cpuz154_x64.sys or similar, depending on the software version). getuidx64 require administrator privileges better

| ID Type | Description | When It Changes | Security Implications | |---------|-------------|----------------|------------------------| | | The UID of the user who launched the process | Never changes during the process lifetime | Represents the original caller, even after privilege escalation | | Effective UID (EUID) | The UID used to determine file access and system permission | Can change with setuid binaries, sudo , su , or seteuid() calls | Determines what the process is allowed to do right now |

Running system utilities like with administrator privileges is generally required for them to interact with protected areas of the Windows operating system . However, doing so also introduces significant security risks if the file's origin is unverified. Why Administrator Privileges are "Better" for Functionality

Always remember to re-enable your antivirus and UAC once you have obtained your UID and finished the installation to keep your system secure.
