parallels desktop windows 10 freezes in sleep mode

Windows 10 worked w/o any problems until recently. I have the same issue with MacOS High Sierra 10.13.6, Parallels 13 and 14 and Microsoft Windows 10 Pro 9. What can be done to remedy Windows 10 guest VM performance issues and freezing? ) but unfortunately none have fixed the problem.

I have made sure I have applied all updates to Parallels, also I have followed the instructions in various knowledge base articles (e.g. Windows is Windows 10 build 1803 - OS build 17143.112 My Mac is running High Sierra version 10.13.5 When the VM freezes the Mac Activity Monitor has the Parallels Desktop process is not listed as 'not responding' - the virtual machine process is there too but not marked as not responding - I have to force quit both processes to restart the VM. My old Windows 7 VMs run without problems. The Mac continues to work without any problems. This can happen after a few minutes if I just start the VM but don't do anything, other times it takes longer e.g. I have recently virtualised a Windows 10 laptop to a virtual machine using the Parallels tools - this VM freezes after a short while - I get the MAC spinning wheel in the VM and the VM is unresponsive. For years I have run Windows 7 VMs using Parallels on the Mac without any problems
