Set the time interval for relaunch

Computer and userIntune-readyRelaunchWindow

Supported on Microsoft Edge version 93, Windows 7 or later

155.0.4283.62

What it does

Specifies a target time window for the end of the relaunch notification period. Users are notified of the need for a browser relaunch or device restart based on the 'RelaunchNotification' (Notify a user that a browser restart is recommended or required for pending updates) and 'RelaunchNotificationPeriod' (Set the time period for update notifications) policy settings. Browsers and devices are forcibly restarted at the end of the notification period when the 'RelaunchNotification' policy is set to Required. This RelaunchWindow policy can be used to defer the end of the notification period so that it falls within a specific time window. If you don't configure this policy, the default target time window is the whole day (that is, the end of the notification period is never deferred). Note: Though the policy can accept multiple items in entries, all items except the first are ignored. Warning: Setting this policy can delay application of software updates. Example value: { "entries": [ { "duration_mins": 240, "start": { "hour": 2, "minute": 15 } } ] } Compact example value: {"entries": [{"duration_mins": 240, "start": {"hour": 2, "minute": 15}}]}

The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
The generated payload is incomplete because one or more ADMX element values were not supplied: RelaunchWindow
