I am having one strange issue with a Windows Server 2008 R2 vm installed on top of ESXi 6.5u2. Kindly check the screenshot below.
The VM has network activities, when I send the ALT+CTRL+DEL from the esxi console menu, it works, however, there is no Windows taskbar, no desktop icon, no desktop activities, even when I right-click the desktop, nothing happens, clicking Windows key+R does not bring the run box, Windows+E does not bring the explorer, nothing. VMware tools is installed. I need to reboot the VM to work normally, but few minutes after the VM reboot, the following problem occurs again.
To note also that, this is a fresh new installed VM, the VM did not crashed.

Clik here to view.
Here is the machine specs, someone might come up with solution that maybe the hardware is not in VMware HCI - I have two other similar machine, on top of them Windows Server 2008 is running smoothly.
