It is part of the machinery that manages the visual presentation and resource allocation of these apps as they transition from an inactive state to a fully functional one.
Furthermore, the “SoftLanding” concept might be tied to performance optimization. By facilitating a smooth and controlled startup, the DLL helps to avoid resource contention that can lead to system slowdowns or visual stuttering. This is particularly crucial on devices with limited resources or when multiple UWP applications are launching simultaneously. Its internal logic is responsible for coordinating with the Windows Shell to handle visual effects, animations, and window management during the crucial initial moments of application execution.
Common Issues and Error Messages Related to Download or Corruption
A missing or corrupt Windows.UI.SoftLanding.dll can manifest as various errors, typically impacting the launch of UWP apps or the stability of the Windows Shell itself. Common error messages reported by users include:
> “The program can’t start because Windows.UI.SoftLanding.dll is missing from your computer.”
> “Windows.UI.SoftLanding.dll is either not designed to run on Windows or it contains an error.”

These issues often arise after a failed system update, a malware infection that has tampered with system files, or an accidental deletion. Unlike third-party DLLs, the correct and safe way to handle a missing or corrupt system file like this is never to download it from an external, unofficial website.
Security Risks of Unverified DLL Downloads
The practice of downloading system DLLs from non-Microsoft sources is a serious security risk. Unverified DLL files, sometimes distributed on “DLL-fix” websites, are prime vectors for malware, including Trojans, Keyloggers, and Ransomware. A malicious DLL can be programmed to load alongside legitimate Windows processes, giving the attacker deep access to the system without the user’s knowledge. Because Windows.UI.SoftLanding.dll is a core system component, replacing it with a malicious version can compromise the entire operating system, leading to data theft or system control by an attacker. Always rely on official Microsoft troubleshooting and repair methods.
Official and Safe Methods to Repair Windows.UI.SoftLanding.dll
When faced with an error related to a missing or corrupt Windows.UI.SoftLanding.dll, the most effective and safest approach is to use built-in Windows repair tools. These tools are designed to scan, verify, and replace corrupted system files with their original, uncorrupted versions stored within the Windows component store.
Method 1: System File Checker (SFC)
The System File Checker (SFC) utility is the primary tool for scanning and repairing critical Windows system files. It checks the integrity of all protected system files and replaces incorrect, corrupted, changed, or missing versions with the correct versions.
Steps for using SFC:
- Press Windows Key + X and select “Terminal (Admin)” or “Command Prompt (Admin)”.
- In the console window, type:
sfc /scannow - Press Enter. The scan will take some time, and upon completion, it will report whether any files were found and repaired.
If the SFC scan is successful, it should restore the legitimate copy of Windows.UI.SoftLanding.dll from the local Windows component store, resolving the error.
Method 2: Deployment Image Servicing and Management (DISM)
The DISM tool is often used when the component store itself (the source for SFC repairs) is corrupted. Running DISM before SFC ensures that the repair source files are intact, making the subsequent SFC scan more effective.
Steps for using DISM:
- Open Terminal (Admin).
- Type the following command and press Enter:
DISM /Online /Cleanup-Image /RestoreHealth - Allow the process to complete, which can take a considerable amount of time.
- After DISM finishes, run the SFC /scannow command again to complete the repair process using the newly validated source files.
Method 3: Windows Update and Feature Updates
System DLL errors can sometimes be resolved by simply installing the latest Windows updates. Major Feature Updates and cumulative updates often contain updated or corrected versions of core system files. Ensuring your Windows OS is fully patched to the latest version as of November 2025 is a key step in maintaining system file integrity. Check for updates in the Settings > Windows Update section.
Troubleshooting UWP App Specific Errors
If the error is isolated to a specific UWP application and the SFC/DISM scans do not resolve the issue, the problem might be with the app’s manifest or its installed state, rather than the core DLL itself. Windows provides tools to address this:
Resetting or Repairing UWP Applications
You can attempt to repair or reset individual applications that fail to launch.
Steps to Repair/Reset:
- Go to Settings > Apps > Apps & features.
- Locate the problematic UWP application (e.g., “Mail and Calendar”).
- Click on the three dots (or the app name) and select Advanced options.
- First, try the Repair option. If that fails, try the Reset option (note: Resetting will delete the app’s data).
Advanced Investigation and Event Viewer
For persistent or intermittent issues, the Windows Event Viewer is an invaluable resource. When an application fails due to a DLL error, an entry is usually logged under Windows Logs > Application or Windows Logs > System. Look for entries with a Level of Error and a Source related to application crashes or Windows Error Reporting (WER). The details of the event will often explicitly name Windows.UI.SoftLanding.dll as the Faulting Module, along with the specific Exception Code, which can provide crucial information for advanced diagnostics.
By cross-referencing the Timestamp of the error in the Event Viewer with the actions you were taking, you can isolate the circumstances under which the DLL is causing issues. This methodical approach is far superior to blindly attempting unverified downloads or fixes.
