This guide will walk you through easy-to-follow instructions to troubleshoot and fix the musnotification.exe error on Windows 11.

Whether you are a beginner or have some experience with Windows troubleshooting, these steps are designed to be clear and helpful.

Quick Note Before You Start

Before diving into the fixes, here are a few quick checks to perform:

  • Make sure your Windows 11 system is up to date by checking Windows Update.
  • Confirm that your internet connection is stable, as some fixes require downloading updates or files.
  • Close any unnecessary applications to prevent interference during troubleshooting.
  • Create a system restore point if possible, so you can revert changes if needed.

Step 1: Restart Your PC

Sometimes, a simple restart can resolve temporary glitches causing the error. Restarting refreshes system processes and clears memory issues.

  1. Click on the Start button or press the Windows key.
  2. Select Power and then Restart.
  3. Wait for your PC to reboot and check if the error still appears.

Step 2: Run Windows Update Troubleshooter

Since musnotification.exe is linked to updates, running the built-in Windows Update troubleshooter can automatically detect and fix related problems.

  1. Open Settings by pressing Windows + I.
  2. Navigate to System > Troubleshoot > Other troubleshooters.
  3. Find Windows Update and click Run.
  4. Follow the on-screen instructions and allow the tool to complete its process.
  5. Restart your PC after the troubleshooter finishes.

Step 3: Check and Repair System Files

Corrupted system files can cause notification errors. Using the System File Checker (SFC) tool helps scan and repair these files.

  1. Press Windows + S, type cmd, then right-click Command Prompt and choose Run as administrator.
  2. In the command window, type sfc /scannow and press Enter.
  3. Wait patiently as the tool scans and fixes any detected problems.
  4. After completion, restart your PC and check if the issue persists.

Step 4: Reset Windows Update Components

If the error still occurs, resetting Windows Update components can resolve deeper update service issues.

This process involves stopping update services, deleting temporary files, and restarting services.

  1. Open Command Prompt as administrator again (see Step 3).
  2. Type each of the following commands one by one, pressing Enter after each:
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
ren C:WindowsSoftwareDistribution SoftwareDistribution.old
ren C:WindowsSystem32catroot2 Catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver

These commands stop update services and rename update folders so Windows can recreate them fresh.

After running these commands, restart your PC and test if the error is resolved.

Step 5: Perform a Clean Boot

Sometimes, third-party software conflicts can cause notification errors. Performing a clean boot helps identify if this is the case by starting Windows with minimal services.

  1. Press Windows + R, type msconfig, and press Enter.
  2. Go to the Services tab.
  3. Check Hide all Microsoft services.
  4. Click Disable all.
  5. Next, switch to the Startup tab and click Open Task Manager.
  6. Disable all startup items by right-clicking each and selecting Disable.
  7. Close Task Manager and click OK in the System Configuration window.
  8. Restart your PC.

If the error disappears, you can enable services and startup items one at a time to find the culprit.

Alternative Method: Scan for Malware

Malware infections can sometimes disguise themselves as system files and cause errors. Running a full system scan using Windows Defender or a trusted antivirus can rule out this possibility.

  1. Open Settings and select Privacy > Windows Security.
  2. Click Virus & threat protection.
  3. Choose Scan options and select Full scan.
  4. Click Scan now and wait for the process to complete.

Remove or quarantine any threats found and restart your PC.
