Microsoft recently announced its 365 Copilot upgrade, but it looks like the tech giant has announced it in November 2022 Quietly starting to work on AI integration in Windows 11 and 10. An unknown Microsoft 365 update adds "Artificial Intelligence (AI) Host" to Windows 11 and 10, in addition to AI Manager.

When you expand Microsoft Word or other Office applications in Task Manager, you'll notice the new artificial intelligence (AI) host. AI Host is being added to all Windows installations via Microsoft Office updates. If you don't see it now, you may see it in a future update.

The host is located in the Microsoft Office installation folder on your system drive. Go to Program Files > Microsoft > Office and look at root\vfs\ProgramFilesCommonX64\Microsoft Shared\OFFICE16\. You will notice a new executable file named "ai.exe".

Microsoft 365 update has another one called " AIMgr.exe", which represents the Artificial Intelligence (AI) Manager for the Microsoft® Windows® operating system and platform x64.

So what’s going on and why is your task Is there AI.exe in the manager process list?

Recent changes to Microsoft Office desktop applications on Windows have resulted in native artificial intelligence (AI) being moved out of the process.

Word, Outlook, and PowerPoint now communicate with a separate program, ai.exe, to perform most native AI functions. Key binaries associated with native AI in Microsoft Office desktop applications on Windows include aitrxdll, ai.exe, ai.dll, mlg.dll, and aimgr.exe.

aitrxdll transceiver library is loaded by Office desktop applications to transmit input to and receive output from ai.exe, which hosts ai.dll. The latter receives input from aitrxdll and processes them through ai.dll to produce output, which is then transferred back to aitrxdll in the Office desktop application.

Meanwhile, mlg.dll is a natural language processing library that contains code created by the Microsoft Machine Learning Group (MLG). Aimgr.exe is a manager executable file used to manage various instances of ai.exe across Office desktop applications.

These changes have significant implications for the future of native AI in Microsoft Office desktop applications on Windows.

We believe these changes may be related to support for Microsoft 365 Copilot integration. The software giant has yet to publicly acknowledge or document the change, which has raised concerns among privacy advocates and users.

It remains to be seen whether Microsoft will clarify the matter soon.

Microsoft 365 Copilot update; when is it coming and what’s new?

Microsoft 365 Copilot uses OpenAI’s ChatGPT-4 as part of the tech giant’s efforts to make users work smarter and faster. The move follows a significant investment in OpenAI, the company behind ChatGPT and Bing’s chat AI.

We've got early versions of Copilot for Word and other apps in Windows 10 and Windows 11. In our tests, we observed that Copilot can handle basic things like formatting, rewriting, suggesting improvements, and generating new text.

Also impressive in analyzing complex data in Excel and making suggestions for improvements. In the future, Copilot can create summaries and recommended action plans, synchronize your work across the Office suite so you can pick up where you left off, and create PowerPoint slides using summaries in Excel or Word.
