Windows 10 VM Freezes in Parallels 13 - Windows 7 VMs are OK
I have the same issue with MacOS High Sierra 10.13.6, Parallels 13 and 14 and Microsoft Windows 10 Pro 10.0.16299. Windows 10 worked w/o any problems until recently. Last week we installed Windows updates. 

In order to reduce the number of possible issues, Parallels support recommends to disable all third party services (to include the ones started during startup). I just did this except for Symantec (this application runs for years w/o problems and would require a de-install). On the list of third party services now disabled are Google and Adobe.

I'm advised to get back to Parallels support if the problem occurs again.

Update: Today I experienced a sudden crash. Screen of MV and Mac freezed and after a few seconds the Mac rebooted. There was no way to switch to the Mac host. Received a crash dump after the login completed (indicating graphics problems). I'm back on square one. A session/chat with Apple support showed that there are no hardware problems. I was advised to reset SMC and NVRAM/PRAM. Completed both tasks. At the moment I'm testing again. 

Update: Since the reset of SMC and NVRAM/PRAM (3 days), the problem has not occurred.
