The most straightforward workaround is to provide the required privileges.
If you do not run GetUid-x64 as an administrator, the program will likely either freeze, show an error, or generate a null/blank value because it was denied access to the necessary hardware queries. 3. How to Properly Run GetUid-x64 as Administrator
If it’s in C:\Program Files\ or a specific hardware folder (like C:\Program Files\Intel ), it is likely legitimate.
Depending on whether you are an end-user trying to run a tool or a developer writing the code, there are several ways to resolve this issue.
(like Cobalt Strike’s getuid command). The agent calls getuidx64 to determine the compromised user context, but if the agent is running in a medium-integrity process, it will request elevation. getuidx64 require administrator privileges
Windows uses a security feature called . UAC blocks standard user accounts—and sometimes even non-elevated administrator accounts—from accessing deep system hardware information. The error triggers due to three main scenarios:
This public link is valid for 7 days and shares a thread, including any personal information you added. This link or copies made by others cannot be deleted. If you share with third parties, their policies apply. Can’t copy the link right now. Try again later.
If you must run the application without true admin rights and trust the source, you can try:
: It generates a unique 8 or 10-digit UID (Unique Identifier) based on your computer's hardware. The most straightforward workaround is to provide the
CloseHandle(hToken); return elevation.TokenIsElevated != 0;
Query %USERNAME% or %USERPROFILE% via standard APIs, which are always accessible to the local user context. Conclusion
Rarely, getuidx64 might be part of a driver or kernel-level component. Kernel modules always run with the highest privilege ( Ring 0 ), but loading them requires administrative rights.
If modifying the shortcut doesn't work, you need to apply the rule directly to the specific file causing the issue. How to Properly Run GetUid-x64 as Administrator If
Many Unix applications are written assuming they can always check their UID. When ported to Windows naively, they fail to handle restricted user contexts gracefully, causing a crash or an explicit privilege check.
Some flawed implementations of getuidx64 try to read from protected kernel memory regions or system configuration files (like SAM or SECURITY registry hives) to map Windows users to Unix UIDs. Accessing these locations triggers a User Account Control (UAC) prompt.
If the tool is optional, look for a version that doesn’t require getuidx64 . Some Unix‑ported tools offer fallback mechanisms using GetCurrentProcessId() and GetTokenInformation() without needing admin rights—check the build configuration.
