Very peculiar. I've never heard of an I/O bottleneck that disappears with user elevation.
Is there an antivirus, data loss-prevention, or auditing agent running on the impacted hosts?
I'm trying to envision how this could happen. The only scenario that comes to mind is one of the above agents on a virtualization host either mis-configured or malfunctioning.

What is the Host and what is the HDD technology?

Hello,
We have the problem, when we copy a big file in the background from our Networkshare to a local drive on the host PC (not to the VM) and parallel use a VM, the VM freezes and get unresponsive. For the copy time.
This only occurs, if the VMware Workstation isn't started with Admin rights.
When I start the Workstation with Admin Rights everything is fine.
Also this only occurs if the file is copied from a SMB Share, if I move this locally between drives, everything works fine.
We see this with Version 25H2 and 17.5.4
Has some else seen this problem?
