There is this long-running issue in Windows 10 where you get the error “Windows cannot find C:/Program Files/WindowsApps/Microsoft.549981C3F5F10” whenever you start up your PC.

How to Fix “Cannot Find Files WindowsApps Microsoft 549981c3f5f10…”

Windows offers different tools to repair or clean corrupted files; three tools can help you fix this issue: Disk Cleanup, System File Checker, and the DISM clean tool.
I recommend you run these three tools in the order below:

Method 1: Use the Disk Cleanup tool

  1. Launch the Run dialog by pressing Win + R.
  2. Type cleanmgr on the Run dialog, then press Enter to open the Disk Cleaner:
  3. Check the Setup log files, Temporary Files, and the Recycle Bin boxes.
  4. Click on the Clean up system files button and wait for a while:
  5. Reboot your PC.

Method 2: Run the System File Checker

  1. Type Command Prompt on Windows Search, then click on Run as Administrator:
  2. Enter the following command on the Command Prompt:
    sfc /scannow
  3. Press Enter and wait patiently while Windows check your system for corrupted files.

Method 3: DISM clean tool

  1. Type Command Prompt on Windows Search, then click on Run as Administrator.
  2. Enter the following command on the Command Prompt and press Enter:
    DISM /Online /Cleanup-Image /Scanhealth
  3. Then enter the following command and press Enter again:
    DISM /Online /Cleanup-Image /RestoreHealth
  4. Wait.


To fix the “Windows cannot find C:/Program Files/WindowsApps/Microsoft.549981C3F5F10” error, you need to reset Cortana. You can do this in Settings -> Apps and Features -> Cortana Advanced Settings -> Reset.
If this doesn’t work, you can try running Windows maintenance tools such as Disk Cleanup, System File Checker, and DISM.

If you often see a pop-up with the error message “C:\ProgramFiles\WindowsApps\Microsoft.YourPhone(…) \PhoneExperienceHost.exe”, check the article I’ve written on it.

My first desktop computer, back in the 1990s, opened a whole new world for me; since then I am a heavy PC user (who will never get used to smartphones.) I worked for five years in the PC software industry, and my favorite version of Windows is still Windows 95.
