While running guest Win 7 on host Win 10 using Player, never had an issue. While running guest Win 10 on Host Server 2019 I am regularly seeing HAL_INITIALIZATION_FAILED issues on the guests overnight, 2-3 times a week, requires restarting VMs in the morning. It doesn’t always happen to all VMs, sometimes only 1 or 2, while other VMS might not be affected. All VMs are set up the same (clones). Sleep is disabled on guests.
Don't know, but what makes you think it is VMware related?
Does TEMP/TMP logging tell you anything? What does it say in Event Viewer? What Windows 10 version you have (like 2004 or something)? If you have some security software (virus scanners, perhaps others with fire walling, or others), can they create this kind of situation (I mean, they surely can, but do they?) Do you have latest Windows Updates ... well, what can I say, they do introduce also new bugs in new Updates, so it's a mess, but seriously outdated Updates can cause problems with very new application versions. Any bad application can cause any other application to fail - but, probably not cause a HAL-related problem, I think ... but you didn't say what kind of applications you have.
It makes sense to have this same Windows error on multiple VMs since they are (near) clones.
EDIT: Actually, this is on a wrong discussion thread, but I'm sure a Moderator wants to move this under Pro.
