The api-ms-win-core-sysinfo-l1-1-0.dll is a system-provided library file belonging to the Microsoft Windows Operating System. It is an ApiSet Stub DLL, which serves as an interface routing layer redirecting application calls to the core Windows APIs responsible for retrieving system information (such as CPU, architecture, memory, and OS details).

Standard File Locations

Depending on your Windows architecture, this file resides natively in the following directories:

  • C:\Windows\System32\ (For 64-bit files on 64-bit systems, or 32-bit files on 32-bit systems)
  • C:\Windows\SysWOW64\ (For 32-bit files on 64-bit systems)
  • C:\Windows\System32\downlevel\ (Standard local fallback repository inside Windows)

How to Fix the Error Without Downloading the File

Downloading isolated .dll files from untrusted third-party websites can introduce malware or cause compatibility mismatches. You can fix this error natively using built-in Windows features and tools:

1. Copy the File from the Local "Downlevel" Folder

Windows maintains local backup stubs of ApiSet files inside the System32 directory. You can restore it manually:

  1. Open File Explorer and go to C:\Windows\System32\downlevel\.
  2. Locate the file api-ms-win-core-sysinfo-l1-1-0.dll.
  3. Copy it, then navigate back to C:\Windows\System32\ or the installation folder of the crashing application.
  4. Paste the file there.

2. Run System File Checker (SFC) and DISM

Windows can automatically repair or replace missing system core components using its internal component store:

  1. Click the Start menu, type cmd, right-click Command Prompt, and select Run as Administrator.
  2. Execute the Deployment Image Servicing and Management tool first:
    DISM.exe /Online /Cleanup-image /Restorehealth
  3. Once finished, run the System File Checker scan:
    sfc /scannow
  4. Restart your computer after completion.

3. Repair or Reinstall the Associated Application or Game

If the file is missing specifically for a certain game or software:

  • Steam/Epic Games: Right-click the game, select Properties > Installed Files, and click Verify integrity of game files.
  • Standard Software: Open Settings > Apps > Installed Apps, locate the problematic program, click Modify/Advanced, and choose Repair or Reinstall.

4. Run Windows Update

Since this stub file is tied to the operating system's internal API configuration, installing pending Windows updates will patch missing system framework stubs:

  1. Go to Settings > Update & Security (or Windows Update).
  2. Click Check for updates and allow Windows to download all system updates.
  3. Restart your PC.

If the error continues to occur with a specific game or software program, please let me know what application or game you are trying to launch and your Windows operating system version so I can provide customized troubleshooting steps.
