Getuidx64 Require Administrator Privileges | Exclusive

Report: getuidx64 requiring administrator privileges (exclusive)

Summary

• provide a concrete code example demonstrating how to check and enable required privileges in a Windows x64 process,
• or outline a secure helper-service design to perform the privileged GetUidx64 call.

Understanding getuidx64

If the error persists, it may be due to folder-level restrictions. You can adjust these via the Local Security Policy or file permissions:  getuidx64 require administrator privileges exclusive

BOOL IsHighIntegrity() 
    HANDLE hToken = NULL;
    if (!OpenProcessToken(GetCurrentProcess(), TOKEN_QUERY, &hToken)) return FALSE;
    DWORD dwLengthNeeded;
    TOKEN_MANDATORY_LABEL *ptml = NULL;
    GetTokenInformation(hToken, TokenIntegrityLevel, NULL, 0, &dwLengthNeeded);
    ptml = (TOKEN_MANDATORY_LABEL*)malloc(dwLengthNeeded);
    BOOL ret = FALSE;
    if (GetTokenInformation(hToken, TokenIntegrityLevel, ptml, dwLengthNeeded, &dwLengthNeeded)) 
        DWORD dwIntegrityLevel = *GetSidSubAuthority(ptml->Label.Sid, 
            (DWORD)(UCHAR)(*GetSidSubAuthorityCount(ptml->Label.Sid)-1));
        ret = (dwIntegrityLevel >= SECURITY_MANDATORY_HIGH_RID);
Step 5: Modify the Application’s Manifest (For Developers/Modders)
If you have control over the software, you can embed a manifest that forces requireAdministrator and uiAccess="true" for exclusive rights. provide a concrete code example demonstrating how to

| Bad Practice (Causes Error) | Good Practice (No Exclusive Needed) |
| :--- | :--- |
| Call raw getuidx64 expecting POSIX behavior. | Use GetCurrentProcessId() or GetProcessIdOfThread(). |
| Try to open \\.\PhysicalDrive0 directly. | Use volume handles (\\.\C:) or WMI queries. |
| Require SeDebugPrivilege for all features. | Use AdjustTokenPrivileges only when needed, and degrade gracefully. |
| Assume admin == root. | Check for IsUserAnAdmin() (shell32) or TokenElevationTypeFull. |
