Script to send scheduled notifications to Windows device
Organizations manage a large workforce and numerous devices, which demands the need for seamless communication. Hence, sending notifications to devices is a timeless requirement. Such notifications can range from reminder messages for upcoming meetings, alerts regarding a suspected security breach to warnings about potential Wi-Fi outages. It would be convenient if IT administrators could just enter the content of the notification and push it to all devices simultaneously. Even better, they could schedule these notifications for a specific time in the future, eliminating any risks associated with time-sensitive messages. With Hexnode UEM, they can do so for Windows devices by running the script given below using the Execute Custom Script action.
The sample scripts provided below are adapted from third-party open-source sites.
