Question

I've already cleaned the virus, but now the shutdown, power off, etc. menu won't open. What should I do?

Answer 1

Hi,

If the virus is already removed but the Start power menu (shutdown, restart, sleep) is not opening, this is usually caused by damaged system files or broken Windows components, not the virus itself anymore.

First, try a quick restart using keyboard shortcuts:

Press Ctrl + Alt + Delete and choose the power icon there, or press Alt + F4 on the desktop and select Restart.

If the menu is still broken, run a system repair:

1: Restart explorer.exe

On your keyboard, press Ctrl + Shift + Esc.

Go to the Details tab.

Scroll down and find explorer.exe.

Right-click on it and select End task.

In the menu bar, click File.

Click Run new task.

Type explorer.exe and press Enter.

2: Re-register all Windows apps

1. On your keyboard, press Ctrl + Shift + Esc
2. Click on File and choose "Run new task"
3. Type: powershell. Make sure to put a check on the "Create this task with administrative privileges" box
4. Copy and paste the command below then press Enter.

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Get-AppxPackage Microsoft.Windows.ShellExperienceHost | foreach {Add-AppxPackage -register "$($_.InstallLocation)\appxmanifest.xml" -DisableDevelopmentMode}

Note: Please ignore any red errors and tet the process complete and then restart your PC.

3: Run SFC and DISM to fix corrupted system files.

Restart your computer.

4: If that fails, the next step is to try System Recovery without deleting your files and apps.

Click the Start menu > Settings > System > Recovery.

Choose Reinstall Now under the section labeled 'Fix problems using Windows Update.'

Once completed, your system will restart. Please check afterward.

Answer 2

Run an additional malware cleanup and then repair Windows components that may have been damaged.

1. Run the Malicious Software Removal Tool
   1. Press Windows key + R to open the Run dialog.
   2. Type %windir%\system32\mrt.exe and select OK.
   3. If prompted, allow the app to make changes.
   4. Run a full scan and remove anything found.
   5. Restart the PC.
2. Install the latest Windows updates
   1. After restart, manually install the latest Windows updates as described in the documentation for installing the latest updates.
   2. This helps restore and patch system components that malware may have modified.
3. If problems persist If malware caused irreversible changes (for example, system menus like shutdown still do not work correctly), reset or reinstall Windows:
   1. Back up important files to an external location (such as OneDrive or an external drive).
   2. Use Windows recovery options (Reset this PC, restore, or reinstall) to repair the system.
   3. After recovery, ensure all Windows and application updates are installed.

If the shutdown menu still does not open after these steps, a reset/reinstall is the supported way to return the system to a healthy state after malware damage.
