How to Fix Errors Without Downloading Anything

DLL errors usually happen because of file corruption or registry glitches. You can fix them using built-in Windows tools. Do not download DLL files from third-party websites, as they often contain malware.

Step 1: Run SFC and DISM Scan

Windows can automatically find and replace corrupted system files from its own secure backup.

Press Windows Key + X on your keyboard.
Select Terminal (Admin) or Command Prompt (Admin).

Type this command and press Enter:

DISM.exe /Online /Cleanup-image /Restorehealth

Wait for the progress bar to reach 100%.
Type this command next and press Enter:
```
sfc /scannow
```
Restart your computer after the scan finishes.

Step 2: Use Windows Memory Diagnostic

Since this specific DLL handles hardware memory policies, a RAM issue might trigger the error.

Press Windows Key + R to open the Run dialog box.
Type mdsched.exe and press Enter.
Click Restart now and check for problems.
The computer will restart and test your RAM for physical defects.

Step 3: Check for Windows Updates

Installing the latest system updates often fixes bugs in native WHEA components.

Press Windows Key + I to open Settings.
Go to Windows Update.
Click Check for updates.
Install all pending updates and restart your device.
