Microsoft Excel unremovable Copilot button

Windows Central reported on May 19 that Microsoft’s floating Copilot button in Excel is drawing complaints from users who say the control takes up worksheet space and cannot be removed. The report described the backlash as centered on a persistent on-sheet button rather than the existing Copilot entry on Excel’s ribbon. Office Watch, which wrote about the same interface change on May 13, said Microsoft had replaced the ribbon button in Word, Excel and PowerPoint with a permanent floating icon in the lower-right corner of documents, sheets and slides. Microsoft’s own support pages still describe Copilot in Excel as a feature available through the Home tab for licensed users, showing the tension between the older placement and the newer floating control. ### Where is the button actually showing up? Office Watch said on May 13 that the Copilot icon now appears at the bottom right of every document, sheet and slide in Microsoft 365 for Windows and Mac. The site said the icon does not disappear while a user is working and that the only built-in option is to “Dock” it, which shrinks it for the current session rather than removing it entirely. (windowscentral.com) Microsoft Support says Copilot in Excel is available from the Home tab and that users who do not see it should check licensing, account status, update channel and privacy settings. That support guidance, last updated in April 2026, does not describe a permanent floating button or a setting to turn that control off. (office-watch.com) ### Why are Excel users objecting? Windows Central’s May 19 archive entry summarized the issue as an “unremovable Copilot button” that is “driving Excel users crazy with forced AI in spreadsheets.” Neowin, in a report published three days earlier, said users were complaining that the floating control clutters sheets, blocks content and cannot truly be disabled. WinCentral reported on May 19 that criticism was coming from power users and professionals who said the button reduced usable workspace inside Excel and other Microsoft 365 apps. (support.microsoft.com) Office Watch said the button can be shrunk, but only for the current session, and that opening a new file brings it back. The publication said the only full workaround it identified was disabling Copilot completely, which also removes other Copilot access. ### Is this limited to Excel? (windowscentral.com) Office Watch said the same floating icon appears in Word, Excel and PowerPoint. WinCentral also described the backlash as affecting Excel and other Microsoft 365 apps, suggesting the design is part of a broader Microsoft 365 interface change rather than an Excel-only test. (office-watch.com) Microsoft Support’s broader Copilot help page says Copilot should appear in Word, Excel, PowerPoint and Outlook on the web for eligible subscribers, and in desktop apps for licensed Microsoft 365 users. That support page focuses on how to make Copilot appear, not how to hide it. (office-watch.com) ### Has Microsoft acknowledged any Copilot backlash elsewhere? Windows Central’s May archive also lists a separate May 18 report saying Microsoft had confirmed plans to let users restore “Right Ctrl” or “Context menu” behavior on PCs with a dedicated Copilot key. Windows Forum reported that a Windows 11 update later in 2026 will let users remap that hardware key in Settings so it acts as either Right Ctrl or the Context Menu key. (support.microsoft.com) Windows Forum said Microsoft’s support language acknowledged that some customers who relied on those older key functions had experienced workflow problems. The keyboard change is separate from the Excel button, but both disputes involve complaints that Copilot is occupying screen or hardware space users previously controlled. That connection is an inference from the timing and subject matter of the reports, not a statement Microsoft has made in the cited material. (windowscentral.com) ### What can users watch for next? Microsoft Support’s April 2026 guidance says Copilot behavior in Microsoft 365 apps depends in part on update channel and app version, so changes to the floating button may first appear through those rollout paths. Windows Forum said the separate Copilot-key remapping option is due later in 2026 through Windows 11 settings, giving users one concrete Microsoft change to watch while complaints about the Excel button continue.
