Microsoft to Remove Some "Compatibility Mode" Legacy Settings from Word on Win10/Win11 Next Month, Potentially Affecting Layout of Old Documents
IT Home, November 14 news: According to the official admin center announcement MC1551147, Microsoft plans to begin adjusting the Windows 10/Windows 11 desktop version of Word in December 2026, removing some legacy settings in "Compatibility Mode." The macOS desktop version of Word will follow in May 2027.
The official announcement does not specify which legacy settings will be removed, but Word's Compatibility Mode is mainly designed to help users view documents created with older versions of Word. IT Home cites a blog post explaining that after the relevant settings are removed, issues such as text reflow, changes in spacing and page count, and displacement of images and shapes may occur.

Microsoft says the streamlining is intended to simplify document layout processing and provide a more consistent cross-platform experience. For users who still need to view old documents and require the layout to remain unchanged, Microsoft recommends exporting the files to PDF to preserve the original layout.
