Understanding and Troubleshooting Error Code 0xC0000073
Error code 0xC0000073 is a common Windows error that typically indicates a problem with the system's ability to load a required DLL (Dynamic Link Library) file. This can lead to application crashes, program instability, or prevent your computer from booting altogether.
What is the Problem?
The 0xC0000073 error signifies that a program cannot find or correctly access a necessary DLL file. DLLs are essential components containing code and data used by multiple programs. When a program encounters this error, it means there's an issue with locating, accessing, or loading the specific DLL required for its operation.
What Causes Error Code 0xC0000073?
Several factors can contribute to the occurrence of error code 0xC0000073:
- Corrupted or Missing DLL Files: DLL files can become corrupted due to malware infections, improper software installations, or system file corruption. Missing DLLs are often a result of incomplete program installations.
- Conflicting DLL Versions: Having multiple versions of the same DLL installed on your system can lead to conflicts, preventing programs from loading the correct version.
- Registry Errors: The Windows registry stores information about DLL files and their locations. Damaged or incorrect registry entries can prevent programs from finding the necessary DLLs.
- Hardware Issues: In rare cases, hardware problems like faulty RAM or a failing hard drive can contribute to DLL loading errors.

How to Solve Errors
There are several steps you can take to troubleshoot and resolve error code 0xC0000073:
Run a System File Checker Scan
Open Command Prompt as an administrator and run the following command:
sfc /scannow
This utility will scan for corrupted system files and attempt to repair them.
Check for Malware
Run a full system scan with your antivirus software to ensure no malware is interfering with DLL files. Consider using tools like Malwarebytes for an additional scan.
Reinstall the Affected Program
If the error occurs with a specific program, try reinstalling it. This can replace any corrupted or missing DLLs associated with that application. Download the latest version of the program from its official website.
Update Device Drivers
Outdated or incompatible device drivers can sometimes lead to DLL loading errors. Visit your computer manufacturer's website or use Device Manager (accessible through Windows search) to update drivers for relevant hardware components.
Use System Restore
If the error started recently, try using System Restore to revert your system to a previous point in time when it was working correctly. Access System Restore through the Control Panel.
Manually Register DLLs
In some cases, you may need to manually register DLL files. Locate the DLL file associated with the error (you can often find its name in the error message) and open Command Prompt as an administrator. Then, navigate to the directory containing the DLL file using the cd command and run the following command:
regsvr32 dllname.dll
Replace "dllname.dll" with the actual filename of the DLL.
Repair Windows Installation
As a last resort, you can attempt to repair your Windows installation using the Windows Installation Media. This process will scan for and fix corrupted system files without requiring a complete reinstallation. You can download the Windows 10 installation media from Microsoft's website.
Remember to always back up important data before attempting any major system changes.
