What you need to know
- Microsoft 365 apps can now perform an update while a machine is in idle or locked mode, even if the applications are left running.
- The capability is known as "update under lock," and it uses Microsoft's Click-To-Run technology.
- Office apps will find a safe time to update and implement the changes in a process that takes roughly four seconds.
Microsoft 365 apps, including Word, Excel, and PowerPoint, can now perform updates while a system is idle or locked. The new feature is called "update under lock," and it utilizes Microsoft's Click-To-Run technology. When enabled, update under lock will find a safe time to shut down an app, perform an update, and then restore closed apps to their previous state.
Microsoft shares an example of when the new feature could be useful in a Tech Community post (opens in new tab).
"A common scenario is for users to leave apps open on their device for extended periods of time. For example, if a user is working on a Word document at the end of the day, they may leave the document open and lock the device intending to continue working on it the next day. When users leave their documents open in this manner, it prevents Office from applying updates. With this feature, the user will come back to a machine in its previous state, but they will be running the latest bits."
Update under lock will not shut down an app when it's unsafe to do so, such as when a macro is running or the document has unsaved changes.
The following Windows devices will be affected by the change:
Windows devices only for
- Microsoft 365 subscriptions, Visio, Project, but not Microsoft Teams, which has its own update process
