If you suddenly see the AI assistant in Microsoft Word (maybe the new version of Clippy or other similar tools), but you want to close it, you can try the following methods:

Disable the assistant function:

Many times, the assistant function will have an option to turn off or disable. You can find out whether there is an option to close the assistant in the menu bar or toolbar of Word. Usually, these options allow you to turn off the assistant temporarily or permanently.

Disable assistant in options:

In Word, you can find and disable the assistant in the options by the following steps:

Open the Word software.

Click "File" in the top menu.

Select the option or Word option (depending on your version of Word).

In the pop-up options window, browse to find the options related to the assistant.

Try to find an option, such as a user interface option or assistant, and then disable or close it.

To uninstall or disable a plug-in:

If the assistant is installed through plug-ins or extensions, you can consider disabling or uninstalling plug-ins in the plug-in management interface of Word.

Update software:

Sometimes, the display of the assistant may be caused by a software version or update. Try updating your Microsoft Word software to see if there is an update that can solve this problem.

If you can't find the option to close the assistant, you can also refer to the official help document of Microsoft Word or search the Internet for ways to close a specific version of the assistant. Please note that different versions of Word may have different interfaces and options.
