Don’t worry — this guide will walk you through detailed, easy-to-follow steps to resolve Windows System Error Code ERROR_84 efficiently.
What is Windows System Error Code ERROR_84?
Before diving into solutions, it’s essential to understand what Error 84 generally means. While Windows doesn’t officially document this specific code as widely as others, it often indicates an issue with system resources, driver conflicts, or corruption in system files. This can manifest during software installations, device driver setups, or even during routine system operations.
Step-by-Step Guide to Fix Windows System Error Code ERROR_84
Step 1: Restart Your Computer
Sometimes, a simple reboot can resolve temporary glitches. Save your work and restart your PC to see if the error persists.
Step 2: Run Windows Update
Outdated system files and drivers can trigger error codes. Ensure your system is up-to-date:
- Press Windows Key + I to open Settings.
- Go to Update & Security > Windows Update.
- Click Check for updates.
- Install all available updates and restart your PC.
Step 3: Run System File Checker (SFC) Scan
Corrupted system files often cause errors. The System File Checker can detect and fix corrupt files:
- Click the Start menu, type
cmd. - Right-click Command Prompt and select Run as administrator.
-
Type the following command and press Enter:
sfc /scannow
- Wait for the scan to finish. It may take several minutes.
- If corrupt files are found and fixed, restart your computer.
Step 4: Check for Driver Issues
Since Error 84 can be related to device or driver conflicts, verify that all your drivers are functioning correctly:
- Press Windows Key + X and choose Device Manager.
- Look for any devices with a yellow exclamation mark.

Step 5: Run DISM Tool to Repair Windows Image
If the SFC scan didn’t fix the problem, running the Deployment Image Servicing and Management (DISM) tool can repair Windows system images:
- Open Command Prompt as administrator.
-
Enter the following command:
DISM /Online /Cleanup-Image /RestoreHealth
- Press Enter and wait for the process to complete.
