read-only mode

About this tag
Read-only mode on Windows and Microsoft software refers to a state where files or applications can be opened and viewed but not edited, saved, or created. This tag covers several scenarios: Microsoft Office 2019 for Mac and Office 2021 on older Apple devices entering reduced functionality after July 13, 2026 due to expired certificates, leaving Word, Excel, and other apps read-only. On Windows, OneNote for Windows 10 becomes read-only after October 14, 2025, requiring migration to the modern OneNote app. Additionally, the CHKDSK utility runs in read-only mode by default unless the F parameter is specified. These examples show how read-only mode can result from license expiration, end of support, or system tool behavior.
