In Intune you can't see how many times a managed device has rebooted
It would be good to see in Intune, the amount of times a device has rebooted. if the device Crashes that's fine we can see that through Desktop analytics but how many times a device has restarted, specifically Win10 devices is not shown in Intune console. You only see "Last login" which in reality doesn't correlate directly with a reboot
just query this: "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters\BootId"
