.NET Prompt May Open a Browser During Windows Agent Upgrade with Lockdown

During a Windows Agent upgrade, the device may reboot before the .NET 10 installation completes. If Auto Logon is enabled, Lockdown may launch prematurely and display a .NET prompt. Selecting any link in the prompt may open a browser outside the Lockdown experience, even though the Lockdown profile remains assigned to the device.

Product: SOTI MobiControl Agent for Windows
Scenario: Agent upgrades with Lockdown and Lock assigned and Auto Logon enabled
Affected Version: Agent 2026.1.3 (observed)

Selecting any link in the .NET prompt opens a browser outside the Lockdown experience. 

During an Agent upgrade, the device may reboot before the .NET 10 installation completes. If Auto Logon is enabled, Lockdown may launch prematurely, causing the .NET installation prompt to appear.

SOTI is developing an agent upgrade change that closes Lockdown before updating its files and restarts it after the .NET runtime installation step.

During the upgrade, the device may display a black screen for approximately one minute while Lockdown is closed. This article will be updated when the fix is available and its distribution details are confirmed.

Recommended Actions

• If the .NET prompt appears, do not select any links.
• Restart the device to complete the .NET installation and restore the Lockdown experience.

If the .NET prompt appears, do not select any links. Restart the device to allow the .NET installation to complete and restore the Lockdown experience.
