The “DDE Server Window: explorer.exe” application error usually shows up as you’re trying to shut down your Windows PC via the Start menu. This happens when the Dynamic Data Exchange (DDE) protocol – which helps different applications on Windows communicate – malfunctions, preventing your device from shutting down. We show you how to get rid of this error so that you can turn off your computer once again.

There are several ways to fix this error, but it’s worth trying some of the more general solutions first, as they’re known to solve a variety of issues on Windows. Try the following:
- Perform an SFC scan: corrupted or damaged systems files can also cause the error, but this is something you can easily fix by running the System File Checker (SFC). Once the tool fixes the broken files that were preventing the shutdown, you should be able to turn off your computer again in Start.
- Update Windows: if you haven’t updated your Windows version in a while, you could run into the “DDE Server Window” error. Easily remedy this situation by going to “Settings -> Windows Update,” and clicking “Check for updates.”
- Turn off third-party antiviruses: if you have a third-party antivirus like Avast, Avira, McAffe, or AVG, they could be causing conflicts between apps, leading to the “DDE Server Window” error. Try disabling your antivirus, then shutting down your computer.
1. Restart Windows Explorer
As part of the error message references “explorer.exe,” restarting the Windows Explorer process may fix the issue.
- Press Ctrl + Alt + Delete, and select “Task Manager” in the menu.
- On the left, select “Processes,” and click “Windows Explorer” from the list of programs. Click on “Restart task” at the top.
- When you’re done, try to shut down your computer in Start to check whether it will turn off as expected.

2. Disable the Option to Automatically Hide the Taskbar
A taskbar that auto-hides can also be the source of this error. Turn off this behavior by following these steps:
- Press Win + I to open the Settings app.
- Navigate to “Personalization -> Taskbar.”
- On Windows 11, expand the “Taskbar behaviors” section, and uncheck “Automatically hide the taskbar.”
- On Windows 10, toggle off the “Automatically hide the taskbar in desktop mode” option instead.
- Check whether you can shut down your computer without encountering the error.
3. Shut Down Your Computer Another Way
If you’ve tried everything above but still can’t shut down your computer via the Start Menu, there are other ways to do so. Hold the power button until the PC turns off (hard shutdown). However, we don’t recommend this, as you can damage your computer and corrupt some files in the long run.

4. Use a Different User Account
If the other ways of shutting down your PC don’t work, try signing out of your account, selecting another user account, and shutting down your computer from there. If you don’t have another account on your PC, consider enabling the Super Administrator account, and using that instead.
5. Reset Your Windows Computer
If all your efforts to get rid of the “DDE Server Window” error haven’t worked, and you don’t want to bother with the workarounds every time you want to shut down your computer through Start, perhaps resetting your Windows PC can help.
Keep in mind that this is a last-resort option that will restore your computer to its factory defaults. That means you’ll lose everything on your PC, including files, apps, and settings.
