Ctrl Alt Del Remote Desktop: Fixes & How-To

Ctrl+Alt+Del doesn’t work in a Remote Desktop session by default—it’s captured by your local Windows machine. To send the secure attention sequence to the remote PC, use Ctrl+Alt+End instead. This article explains why the shortcut behaves differently, how to trigger it in various Remote Desktop clients, and how to fix common issues when it still doesn’t work.

Why Ctrl+Alt+Del Is Different in Remote Desktop

On a physical Windows computer, pressing Ctrl+Alt+Del opens a secure screen with options to lock, switch user, sign out, or open Task Manager. This is called the Secure Attention Sequence (SAS). It’s designed so that no background program can intercept or fake it—only the Windows operating system itself responds.

When you’re in a Remote Desktop session, your keyboard input is sent over the network to the remote machine. If your local computer forwarded Ctrl+Alt+Del as-is, it would trigger the SAS on your local machine, not the remote one. That would lock your local PC or open its Task Manager—which is not what you want. To avoid this, Remote Desktop Protocol (RDP) reserves that combination for the local machine and uses a different one for the remote session.

The Correct Shortcut: Ctrl+Alt+End

To send the secure attention sequence to a remote Windows PC, press Ctrl+Alt+End on your keyboard. This works in the standard Microsoft Remote Desktop Connection client (mstsc.exe) and in most third-party RDP clients.

On some laptop keyboards, the End key is combined with another function and requires pressing the Fn key. In that case, try Ctrl+Alt+Fn+End. If you’re using a Mac with Microsoft Remote Desktop, the equivalent is Fn+Control+Option+Delete (or Control+Option+Delete on some versions).

How to Send Ctrl+Alt+Del in Different Clients

The exact key combination varies slightly depending on the Remote Desktop client you’re using. Here are the most common ones:

• Windows built-in Remote Desktop (mstsc): Ctrl+Alt+End
• Microsoft Remote Desktop for Mac: Fn+Control+Option+Delete (or Control+Option+Delete)
• Remote Desktop Manager: Ctrl+Alt+End (or use the Send Ctrl+Alt+Del button in the toolbar)
• Chrome Remote Desktop: Ctrl+Alt+End (or the on-screen keyboard button)
• VMware Horizon Client: Ctrl+Alt+End (or the Send Ctrl+Alt+Del icon in the client menu)
• Citrix Workspace: Ctrl+Alt+End (or the Desktop Viewer toolbar button)

If you’re using a client that doesn’t have a dedicated button, look for a menu item like Send Ctrl+Alt+Del or Send Keys—it’s often in the client’s toolbar or under a keyboard icon.

How to Enable Ctrl+Alt+Del in Remote Desktop

Some remote machines are configured to ignore Ctrl+Alt+End, especially if they are running Windows Server with specific Group Policy settings. To enable it on the remote machine, you need to change a policy:

1. On the remote PC, press Win+R, type gpedit.msc, and press Enter.
2. Navigate to Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Security.
3. Double-click Set a rule for remote control of user sessions (or look for a policy named Require secure RPC communication—the exact name varies by Windows version).
4. Set it to Enabled or Not Configured as appropriate, then click OK.

Note that Group Policy changes require administrative rights on the remote machine. If you don’t have those, you’ll need to ask the system administrator to make the change.

Common Problems and Fixes

If Ctrl+Alt+End still doesn’t work, try these troubleshooting steps in order:

• Check if the remote session is full-screen. Some clients only forward special keys when the session is in full-screen mode. Press Ctrl+Alt+Break to toggle full-screen, then try again.
• Use the on-screen keyboard. On the remote desktop, click the Start button, type osk, and press Enter. Then click Ctrl, Alt, and End on the virtual keyboard.
• Check if the End key is working. Press End alone in a text editor to confirm it’s not stuck or remapped.
• Try Ctrl+Alt+Fn+End if you’re on a laptop with a compact keyboard.
• Restart the Remote Desktop client. Sometimes the keyboard hook gets stuck, and a restart fixes it.
• Update your Remote Desktop client. Older versions may have bugs with key forwarding.

Alternatives to Sending Ctrl+Alt+Del

If you can’t send the secure attention sequence, there are other ways to achieve the same result:

• Use Task Manager directly: Press Ctrl+Shift+Esc on the remote machine to open Task Manager without the secure screen.
• Use the Start menu: Right-click the Start button and choose Task Manager or Shut down or sign out.
• Use the Ctrl+Alt+Del screen on the remote machine via the client’s menu: Some clients have a Send Ctrl+Alt+Del button in their toolbar that does the same thing as the keyboard shortcut.
• Use PowerShell: If you have administrative access, run shutdown /r /t 0 to restart, or logoff to sign out.

Frequently Asked Questions

Why does Ctrl+Alt+Del lock my local computer instead of the remote one?
Because your local Windows intercepts the key combination before it reaches the RDP client. That’s why the remote session uses Ctrl+Alt+End instead—it’s a different combination that the local system doesn’t reserve.

Does Ctrl+Alt+End work on all versions of Windows?
Yes, it works on Windows 7, 8, 10, and 11, as well as Windows Server editions, as long as the Remote Desktop client is the standard Microsoft one. Third-party clients may use a different combination, so check their documentation.

Can I remap the key to something else?
You can use a keyboard remapping tool like AutoHotkey to send Ctrl+Alt+End when you press a different key combination, but this only works on the local machine and doesn’t affect the remote session’s behavior.

What if I’m using Remote Desktop from a Mac?
On a Mac, the default is Fn+Control+Option+Delete. If that doesn’t work, check the app’s preferences—you can often customize the key combination in the Microsoft Remote Desktop settings.

Does Ctrl+Alt+End work on Linux RDP clients?
Most Linux RDP clients (like Remmina or FreeRDP) support Ctrl+Alt+End, but some may require you to use a menu option instead. Check your client’s keyboard settings or look for a Send special key button.
