You may be using a defective keyboard. This is why the Ctrl+Alt+Del sequence is not working.

You can try using a new keyboard or connecting your existing one to another computer to determine whether the keyboard is causing the problem.

Method 2: Updating your keyboard driver

In some cases, the issue is caused by an outdated or corrupted keyboard driver. To fix the problem, you can try updating your drivers. This can be done manually or automatically.

Manually updating drivers can be complicated and time-consuming. You would have to go to the manufacturer’s website and look for the correct drivers.

Method 3: Changing the settings for your keyboard

It is possible that the Ctrl + Alt + Del sequence occurred when you installed software that automatically modified your default keyboard settings.

It can also show up after you’ve added some custom keyboard shortcuts or hotkeys. So, you can try resetting your keyboard settings to resolve the issue. Here are the steps you should follow:

• Press Windows Key + I on your keyboard. This should open Windows Settings.
• Select Time & Language.
• If you’re currently using only one language, you can add another by clicking the Add a language option under Preferred Languages. Make sure you do not select the Set as my Windows display language option. On the other hand, if you’re already using multiple languages, you can skip this step.
• Select your primary language. It should be the first one on the list. Click the down arrow, then the up arrow to take it back to the top of the list.
• Check if the Ctrl + Alt + Del sequence is now working.

On Windows 11:

• Launch the Settings app, navigate to the Time & Language option in the left pane and select it.

2. Select Language & region and then follow steps 3 through 5 that are described above.

Method 4: Use the ctrl + shift + esc hotkeys

The Ctrl Alt Delete key combination is handy when the PC isn’t responding, as it gives you access to the Task Manager.

However, if it fails to work in the hour of need, you can use the Ctrl + Shift + Esc keyboard shortcut to forcefully shut down any unresponsive programs that could have triggered the error.

Here’s how:

• Press the Ctrl + Shift + Esc keys simultaneously, in that order.
• It should open with the Processes tab selected by default. Find the problematic program that you suspect caused the issue, select it, and click End task at the bottom left corner of the window.
• Repeat the process for all other unresponsive applications.

If you can’t access Task Manager for some reason, press and hold the power button to initiate a hard shutdown.

Your Windows 10 or Windows 11 computer may be infected with malicious software. If that’s the case, follow the steps in Method 5 below to remove the malware.

Method 5: Perform a malware scan

Viruses and malware affect systems in a way that causes certain programs and configurations to malfunction.

You can use the built-in Windows Defender security tool, which does a great job of removing viruses and malware. Here’s how:

• On your Taskbar, click on the Show Hidden Icons option and select Windows Security.
• Select Virus & threat protection -> Scan options.

• Select an option and hit the Scan Now button. For a more thorough scan, choose Microsoft Defender Antivirus (offline scan).

For more reliable results, we recommend utilizing a dedicated antimalware tool.

These programs have a higher detection rate and have been known to detect and eliminate even the most notorious viruses designed to be undetectable.

Method 6: Performing an SFC scan

In some cases, corrupted system files are causing the Ctrl+Alt+Del issue. To determine if this is the reason behind the problem, you can run an SFC (System File Checker) scan.

The tool will locate and repair corrupted Windows system files. Here are the instructions for launching the program:

• Click the Search icon on your taskbar.
• Type cmd.
• Right-click Command Prompt from the results, then select Run as Administrator. If a message appears asking for your consent, click Yes. This should allow you to launch Command Prompt.
• Run the commands below. Press Enter after every command and wait for the process to complete.

Dism /Online /Cleanup-Image /CheckHealth
Dism /Online /Cleanup-Image /RestoreHealth|
sfc /scannow

• Once you’ve successfully run the aforementioned commands, you can now close Command Prompt. Try pressing Ctrl + Alt + Del and check if the problem has been fixed.

Method 7: Modifying your registry

Some users reported that third-party software automatically made some changes to their registry. So, in your case, it possibly modified the default values. You can fix this by getting the value back to its default value.

Before proceeding, you must know that the registry is a sensitive database. This means that even a single punctuation error can damage your computer.

So, you should only go ahead with the steps only when you are absolutely confident that you can follow the instructions down to the smallest detail.

Otherwise, you should just ask a professional to do this for you.

Better still, be sure to backup your registry using the steps below:

• Finally, click Save.

That said, here are the instructions for correcting the default settings on your registry:

• Press Windows Key + R on your keyboard. This should bring up the Run dialog box.
• Type regedit, then hit Enter.
• Navigate to the following path:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System

• If that path does not bring up results, you can go to:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies

• Right-click Policies, then choose New.
• Create a new key by selecting Key from the list. Set the name of the new key to ‘System’. You can skip this step if a key named System already exists.
• Go to the right panel, then double-click DisableTaskMgr. This will allow you to view its properties.
• If you can’t see DisableTaskMgr, you can right-click System. Select New, then click DWORD (32-bit) Value. Set the name of this new DWORD entry to DisableTaskMgr. Double-click it to view its properties.
• Make sure that the Value Data is set to 0 (zero).
• Restart your computer, then check if the Ctrl + Alt + Del keyboard shortcut is now working.

Method 8: Performing a clean boot

At this point, you might wonder, “Why does not CTRL ALT DEL combination work on Windows 10/11?” Well, don’t give up just yet. In some cases, certain startup programs and services might be causing the problem.

Here’s how you can perform a clean boot:
