【#Tech24H】Microsoft has made a significant decision to gradually phase out, starting December 2025, and fully retire the classic "Reuse Slides" feature in PowerPoint on Windows 11 and macOS platforms by January 2026. The "Reuse Slides" feature, an important built-in PowerPoint tool, has served users for over a decade. Throughout its long service, its powerful functionality made it an essential assistant for many users creating presentations. Analysis suggests that with ongoing technological development and continuous software iteration, Microsoft likely considers the "Reuse Slides" feature no longer fully capable of meeting users' increasingly diverse and complex needs.
