U3821DW, firmware M2B107 keeps processing

Hi all,

I started the firmware update for my Dell U3821DW monitor. The Version is M2B107. The update was available as optional through the Dell Display Manager. I started the update several hours ago. It is still "processing" although it is at 100%. Nothing else happens. I don't know how to stop this software from running. See screen shot.

I have read several warnings that disturbing this update may cause harm to your device. Now I don't know how to savely stop the update.

Hope anyone can help. 

Kind regards, 

Hugo

I saw in task manager that the processor used 0% for the update proces. I supposed this meant that the proces in fact was already stopped. So I ended the task. Nothing bad happened (so far). Problem solved.
