After have patched the ESXi hosts (6.5) and updated the VMware tools on the VDI master, the new VM's display freeze after a few seconds.
What's "funny" is that if you run a command, it's processed but not displayed.
I had to uninstall the VMware tools, and reinstall the former ones to get rid of this.
VMware tools version causing issues : 10.2.1 build 8267844
Former VMware tools version : 10.1.7 build 5748532
Master O/S : Windows 10 x64 v1709, 2 vCPU, 8Gb RAM
Did you already see that ?
Did not experience this with VMware Tools but often related to Antivirus locking up the System.
Have you tried using recent VMTools Version e.g. 10.3.2 ?
As u are goint with 10.2.1 i assume your ESXi Host have not been patched? Right?
On the server VMs, I didn't have issues.
Only VDI VMs.
The tools version was the one provided by the ESXi hosts (patched to 10719125, ESXi 6.5 EP 11).
10305 esx/6.5ep11 10.2.1 10719125
Oh maybe mixed up the tools versions.
Before Upgrading please check here:VMware Product Interoperability Matrices
Maybe you experienced something like an issue with Horizon Agent 7.3.1 isn't supported with newer Tools version as seen in the matrices.
