Path: C:\Windows\SystemApps\Microsoft.Windows.SecHealthUI cw5n1h2txyewy\

How to Fix sechealthuitelemetry.dll Errors (Without Downloading Anything)

Errors related to this file usually happen because the file is corrupted, missing after a buggy Windows update, or blocked by system permissions. You do not need to download sketchy third-party DLL files to fix it.

Follow these native Windows solutions:

Method 1: Repair and Reset the Windows Security App

Since this DLL belongs to the Windows Security app package, resetting the app will restore all its original files.

Press the Windows Key + i to open Settings.
Click on Apps and then select Installed apps (or Apps & features).
Search the list for Windows Security.
Click the three dots (...) next to it and select Advanced options.
Scroll down and click the Repair button. Wait for it to finish.
If the error persists, go back and click the Reset button.

Method 2: Re-register Windows Security via PowerShell

If the app framework is broken, you can force Windows to reinstall and re-register the security interface using a built-in command terminal.

Right-click the Start Menu button and select Terminal (Admin) or PowerShell (Admin).

Copy and paste the following command, then press Enter:

Get-AppxPackage -AllUsers -Name Microsoft.Windows.SecHealthUI | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "( .InstallLocation)\AppXManifest.xml"}

Restart your computer.

Method 3: Run SFC and DISM System Scans

Windows has built-in repair tools that scan your system directory, find corrupted or missing DLLs, and automatically replace them with clean, cached versions.

Type cmd in your Windows search bar.
Right-click Command Prompt and choose Run as administrator.
Type the following command to check your system health and press Enter:
```
DISM.exe /Online /Cleanup-image /Restorehealth
```
Wait for the progress bar to hit 100% (this can take a few minutes).
Next, type this command and press Enter:
```
sfc /scannow
```
Once the verification states "100% complete", restart your PC.

Method 4: Install Pending Windows Updates

Microsoft frequently pushes hotfixes for broken native apps like Windows Security.

Open Settings (Windows Key + i).
Go to Windows Update.
Click Check for updates.
Download and install all available updates, then restart your device.
