Article summary

Scalefusion offers numerous capabilities on Windows devices managed by them. With various security policies the device administrators ensure data protection at every possible level. Enabling Lost mode on devices is one such special feature where a device, if lost or stolen, can be marked as lost preventing its further usage even on restart. In large organizations where windows devices are being used by employees sitting in different geographical regions, it is likely that device can be lost or stolen or missing. Locking down the device remotely restricts the usage of device hence safeguarding the essential corporate data from being misused if the device falls into unknown hands.

With Lost mode being enabled, the device user sees a customized message on their lock screen which may also help with device recovery. Devices will remain in lost mode until the administrator disables it to regain the access and use it again in normal managed state.

Let us understand how simply Lost mode can be remotely enabled and disabled on Scalefusion managed Windows devices right from Scalefusion Dashboard.


  1. Lost Mode is supported on Windows OS 10 and 11.
  2. Devices should be enrolled with Scalefusion.
  3. This feature requires the latest version of Scalefusion MDM agent (agent app for Windows) installed on the devices.
