== 默认字体更改 ==
在Office 2021生命周期的中期，经过两年对五种新启用字体的评估，7月份，<ref>{{Cite news |title=Beyond Calibri: Finding The Next Microsoft 365 Default Font |url=https://medium.com/microsoft-design/beyond-calibri-finding-the-next-microsoft-365-default-font-5ef83f028be2 |last=Design |first=Microsoft |work=Medium |date=2021-04-28 |language=en |access-date=2025-07-23 |archive-url=http://web.archive.org/web/20250711183705/https://medium.com/microsoft-design/beyond-calibri-finding-the-next-microsoft-365-default-font-5ef83f028be2 |archive-date=2025-07-11}}</ref>所有Office应用程序的默认字体更改为[[Aptos]]。<ref>{{Cite web |title=New Office theme - Microsoft Support |url=https://support.microsoft.com/en-us/office/new-office-theme-e7bbfe02-d1fb-4c4d-b3b7-6a47f0cefd3f |website=support.microsoft.com |access-date=2025-07-23}}</ref><ref>{{Cite web |title=A change of typeface: Microsoft’s new default font has arrived |url=https://medium.com/microsoft-design/a-change-of-typeface-microsofts-new-default-font-has-arrived-f200eb16718d |website=Microsoft Design |date=2024-02-23 |language=en |last=Design |first=Microsoft |access-date=2025-07-23}}</ref>这是微软16年来首次更改默认字体。

== 用户界面 ==
当Office主题设置为使用系统设置、深灰色、黑色或白色时，默认界面会在每个屏幕顶部显示云母背景（因此得名）；应用程序图标位于左上角。如果选择了彩色（必须手动选择），则每个屏幕顶部都会显示一条应用程序颜色带；这就是所谓的Metro背景。
