Microsoft Says Copilot Is a New OS. So…What Happened to Windows?
Microsoft CEO Satya Nadella said the company is “building Copilot as a new OS for work” after a redesigned Copilot app launched. The article argues that Microsoft has not explained whether this describes an AI framework layered over existing systems, a cross-platform work experience, or a longer-term alternative to Windows. It notes that the announcement did not mention Windows, even as Microsoft appears to be narrowing some Copilot integrations within Windows and emphasizing improvements for developers and power users.
The piece connects that ambiguity to Microsoft’s retreat from Copilot+ PC branding. New Surface Pro and Surface Laptop devices reportedly meet the former requirements and include previously exclusive features, but are not being marketed under that label. The article also points to reduced Copilot visibility in Windows, including the ability to remap the Copilot key and the removal of a Copilot button from Notepad.
Separately, Microsoft is ending Publisher support in October. Microsoft 365 subscribers lose access on October 1, while owners of non-subscription versions can continue using the app after support ends on October 13, but will no longer receive security updates. Microsoft recommends Word and PowerPoint for some use cases; the author suggests considering alternatives. Together, these developments show several distinct shifts in Microsoft’s product messaging and support commitments, but the article does not establish a replacement plan for Windows or detail what a Copilot-based operating system would entail.
