Test Agent causing un-commanded reboot

After installing Test Agent 2.0 on my machine (running 64bit Windows10), it (my machine) keeps doing un-commanded reboots.

 

After further investigation, I suspect it may have something to do with the way the Test Agent communicates to QAComplete.

QAComplete is located on a remote server, to which I connect via a secure VPN. I have noticed that the un-commanded reboots happen after I have closed QAComplete and disconnected from the VPN.

The reboots happen around six times before everything stabilises.

 

In the end, for practical reasons, I've un-installed the Agent and everything is as it should be.

 

What is the issue here?
