Encountering Windows 11 DISM errors like 87, 112, or 1726 can be frustrating, especially when you're trying to repair your system. These errors often pop up during Deployment Image Servicing and Management (DISM) operations, halting updates or fixes. But don't worry—🛠️ with the right steps, you can resolve them efficiently and get your PC running smoothly again. This guide focuses on practical, up-to-date solutions to help you troubleshoot and fix these issues without unnecessary hassle.
What Are DISM Errors 87, 112, and 1726 in Windows 11?
The DISM tool is a powerful built-in utility in Windows 11 for servicing and repairing the operating system image. It's commonly used alongside System File Checker (SFC) to fix corrupted files. However, errors can occur due to permission issues, incomplete commands, network problems, or outdated components.
- DISM Error 87: This typically means "The parameter is incorrect." It often arises from syntax errors in commands or insufficient privileges.
- DISM Error 112: Indicates "There is not enough space on the disk." Your drive might be running low on storage, preventing DISM from completing tasks.
- DISM Error 1726: Signals a "RPC server unavailable" issue, usually linked to remote procedure call failures or network-related glitches during online repairs.
Understanding these errors is the first step to fixing them. By the end of this article, you'll have clear, actionable steps to resolve each one, ensuring your Windows 11 system stays stable. Let's dive in! 🚀
Step-by-Step Fixes for DISM Error 87 in Windows 11
Error 87 is one of the most common DISM errors, often triggered by mistyped commands. Here's how to fix it:
- Run Command Prompt as Administrator: Right-click the Start button, select "Terminal (Admin)" or "Command Prompt (Admin)." This ensures proper permissions. Without admin rights, DISM can't execute fully.
- Verify Command Syntax: Double-check your DISM command. For example, the correct syntax for scanning health is:
DISM /Online /Cleanup-Image /CheckHealth. Avoid extra spaces or typos—Error 87 loves those! 😅
- Flush DNS and Reset Network: Sometimes, network cache causes issues. Run these in admin Command Prompt:
ipconfig /flushdns
netsh int ip reset
- Restart your PC and retry the DISM command.
- Update Windows 11: Go to Settings > Windows Update > Check for updates. Recent patches often resolve command parsing bugs in DISM.
If these don't work, try running SFC first: sfc /scannow. It complements DISM and can clear underlying file corruptions. Most users see Error 87 vanish after these tweaks—giving you that satisfying "operation completed successfully" message. 🎉
Resolving DISM Error 112: Free Up Space and Retry
DISM Error 112 is straightforward—your disk is too full. DISM needs temporary space to process image files, often several GB. Here's a focused fix:
| Step |
Action |
Expected Outcome |
| 1. Check Disk Space |
Open File Explorer > This PC > Right-click C: drive > Properties. Aim for at least 20GB free. |
Identifies if space is the culprit. |
| 2. Clean Up Drive |
Run Disk Cleanup: Search for it in Start menu, select C: drive, check "Temporary files" and "Recycle Bin." |
Frees up 5-10GB instantly. |
| 3. Delete Unnecessary Files |
Uninstall apps via Settings > Apps > Installed apps. Use Storage Sense in Settings > System > Storage to auto-clean. |
Reclaims more space without effort. |
| 4. Extend DISM Temp Space |
Set environment variable: In admin CMD, set TEMP=C:\Temp (create folder first), then run DISM. |
Allows DISM to use a dedicated temp area. |
After freeing space, rerun your DISM command, like DISM /Online /Cleanup-Image /RestoreHealth. This error is a gentle reminder to declutter—your PC will thank you with faster performance overall. 💪
Troubleshooting DISM Error 1726: RPC and Network Fixes
DISM Error 1726 points to RPC (Remote Procedure Call) problems, especially when DISM tries to pull files from Windows Update servers. It's more network-oriented, but fixable:
- Restart RPC Service: Press Win + R, type
services.msc, find "Remote Procedure Call (RPC)," right-click > Restart. Also restart "RPC Endpoint Mapper."
- Check Network Connection: Ensure you're online. If on Wi-Fi, switch to Ethernet for stability. Run
ping windowsupdate.microsoft.com in CMD to test connectivity.
- Reset Windows Update Components: In admin CMD, execute:
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 Catroot2.old
- Restart services:
net start wuauserv (repeat for others).
Then retry DISM.
- Offline Repair Option: If online fails, use an ISO. Download the latest Windows 11 ISO from Microsoft's official site. Mount it and run:
DISM /Online /Cleanup-Image /RestoreHealth /Source:WIM:X:\sources\install.wim:1 /LimitAccess (replace X: with ISO drive).
These steps address the root of Error 1726, restoring communication between your system and repair sources. Users often report success on the first try, avoiding deeper dives into registry edits.
General Tips to Prevent Future DISM Errors in Windows 11
To keep Windows 11 DISM errors at bay:
- Regularly update your system via Settings > Windows Update.
- Maintain at least 20% free disk space.
- Run antivirus scans to rule out malware interfering with services.
- Use trusted sources for repairs—avoid third-party tools unless verified.
If errors persist after these fixes, consider a System Restore or Reset PC from Settings > System > Recovery. For advanced users, checking Event Viewer (search in Start) can reveal more clues. Remember, patience pays off—your Windows 11 setup will be rock-solid soon. 👏
