    Great! Since everything works fine in the new account, we can confirm the issue was corruption in the old user profile, likely caused by the virus.


    While there are ways to try to repair the old user account, they are complex, unreliable, and rarely provide a complete solution. Therefore, the most effective and practical alternative is to start using the new user account as your primary account and migrate your data and apps from the old one.


    I'm glad you were able to transfer your apps.

    For the files, you can transfer from the old user account folder to the new user account folder. User account folders are located in C:\Users. There's no need to copy the "AppData" folder, as it often contains what caused the issue.

    Once you're satisfied, you can remove the old user account by following the instructions under "Remove a user account" in the article I shared earlier.

    No problem if you prefer to keep the old user until you're sure you've transferred everything.


    Feel free to ask any questions you may have.

    Thanks for the clarification.


    In this case, I believe the problem might be directly related to the Start Menu, the Windows user account profile, or severe system corruption. Issues that a virus could cause.


    I suggest doing the following:


    Use the system file checker to repair possible corrupted or missing system files.

    1. Press "Ctrl + Shift + Esc" to open Task Manager;
    2. Select "File > Run new task";
    3. In the "Open" field, type cmd, check "Create this task with administrative privileges", and click Ok;
    4. Run the following commands at the Command Prompt one at a time:
    dism.exe /online /cleanup-image /scanhealth
    dism.exe /online /cleanup-image /restorehealth
    dism.exe /online /cleanup-image /startcomponentcleanup
    sfc /scannow
    

    Note: Pay attention to the results of the commands to make sure that the procedure was completed successfully or if there was a problem. If you have any problems, let me know the error that was shown.

    1. Restart (not shutdown) the PC and see if the problem is resolved.

    If it persists, re-register the Shell Experience Host as instructed below.

    1. Press "Ctrl + Shift + Esc" to open Task Manager;
    2. Select "File > Run new task";
    3. In the "Open" field, type powershell, check "Create this task with administrative privileges", and click Ok;
    4. Type or paste the following command and press Enter:
    Get-AppxPackage -AllUsers Microsoft.Windows.ShellExperienceHost | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
    
    • Note if the command will run correctly or will have a red message.
    • If you get a red message, you will need to terminate the "Windows Shell Experience Host" process in Task Manager (Ctrl + Shift + Esc) and run the command again.
    1. Restart (not shutdown) the PC.

    If the problem persists, please let me know.


    Feel free to ask any questions you may have.

    Hi. I'm David, and I'm happy to help you.


    Have you already run any tools to remove the infection from your computer and ensure that the system is clean?


    If not, I suggest you do a full scan using Microsoft Safety Scanner. Download from the link below.

    https://docs.microsoft.com/en-us/windows/security/threat-protection/intelligence/safety-scanner-download

    Also, do a full scan using Malwarebytes as a second opinion.

    Download through this link: https://malwarebytes.com/

    After scanning, you can uninstall it.


    After scanning the system and removing any potential infections, you need to restart (not shutdown) your PC to ensure the infection is completely removed from the system.


    If you've already done that and the problem persists, I suggest you do the procedure below:

    1. Press "Windows + R";
    2. Type or paste C:\Windows\system32\ctfmon.exe and press Enter.
    3. See if the problem is resolved.

    If the problem is resolved with the above procedure, do the following procedure so that the problem does not return after restarting the PC.

    1. Open Start and type cmd, right-click on "Command Prompt", and select "Run as administrator".
    2. Copy the command below, paste it into Command Prompt, and press Enter:
    REG ADD "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run" /T REG_SZ /D "%windir%\system32\ctfmon.exe" /v CTFMON /F
    
    1. Restart (not shutdown) your PC and test.

    If the problem persists, please let me know.

    Run through these checks and fixes in order:

    1. Check the Start menu service dependencies
      1. Press Ctrl+Shift+Esc to open Task Manager.
      2. Select File > Run new task, type services.msc, and press Enter.
      3. In Services, find Background Tasks Infrastructure Service (BrokerInfrastructure).
      4. Make sure Startup type is set to Automatic and the Status is Running. If not:
        • Double‑click it, set Startup type to Automatic, select Start, then OK.
      5. If it fails to start, open Command Prompt as administrator and run:
              sc query pdc
        
        Confirm the STATE is 4 RUNNING. If the PDC driver or its registry key is missing or disabled, restore them from backup or installation media, then reboot and test Start menu typing again.
    2. Repair possible Start menu data corruption
      1. Open Command Prompt as administrator.
      2. Run this command to repair Start menu tile and cache data:
              C:\Windows\System32\tdlrecover.exe -reregister -resetlayout -resetcache
        
      3. Sign out and back in, or restart the PC, and test typing in the Start menu.
    3. Install the latest Windows 10 updates
      1. Select Start > Settings > Update & Security > Windows Update.
      2. Select Check online for updates from Microsoft Update.
      3. Install all available updates and restart.
    4. If the issue started after an upgrade and profiles are roaming (domain/enterprise scenario) If using a roaming user profile and Start menu problems appeared after a Windows 10 upgrade, apply the profile workaround:
      1. Install the latest monthly cumulative update.
      2. As a local admin, create this registry value:
        • Subkey: HKLM\SYSTEM\CurrentControlSet\Services\ProfSvc\Parameters
        • Name: UseProfilePathMinorExtensionVersion
        • Type: DWORD
        • Value: 1
      3. Reboot, then sign in with the roaming profile account and test the Start menu.

    If the virus infection modified system files or services, these steps repair the Start menu infrastructure and layout so typing in Start works again.
