Mapped printers disappearing on VM

[Mario_Rivas]

Hello.  We are running a VDI environment for our W10 v2004 VMs.  Horizon 7.13.1, VMware ESXi 7.0.2 on a vSAN cluster.  We are using domain GPO to map printers for users accessing their VMs.  Too many times, the mapping is failing, printers are disappearing and the default printer is assigned to a different one. When this happens, we have to run a script on the user's VM, which would re-install the printers and re-assigned the default printer.  TP AutoConnect Service and TP VC Gateway Service are both enabled, on the master template, and running on the VMs.  We tried disabling both services, recomposing VMs but got the same results.

Any ideas of what can we do to fix this issue?  Are we missing something?

Thanks

Mario

This could be due to the recent Windows update which introduced a change in printer driver installation. Please see https://communities.vmware.com/t5/Dynamic-Environment-Manager/Windows-Update-KB5005030-Breaking-DEM/...

Hello.  Thanks for your reply.  We do not have DEM running on our Horizon environment.  The registry change recommendation, from the link you sent me, is not present on our VMs.  Users do have local admin rights on the VMs they access.  Also, we use linked-Clone desktop pools.  But, nevertheless, we are looking into this issue as, probably, coming from a Windows Update.

We have, also, opened a ticket with VMware tech support.
