@cg Agreed. The next person can grab the .msp here:
https://github.com/xcp-ng/win-pv-drivers/releases/download/v9.2.385/XenTools-fix-9.2.351.msp
@dinhngtu Could the release note say "attached to this release" instead of "included"? It reads as if the .msp ships inside the zip. And thanks, your answer settled it. Both of my Windows VMs are on 9.2.385 now, and I took fresh full backups after the switch.
When I turned off "Manage Citrix PV drivers via Windows Update" (has-vendor-device=false) to switch from XenServer VM Tools, Windows treated the NICs as new adapters. The static IPs were gone and one NIC came back on the Public firewall profile. Have console access ready, or a startup script that puts the IPs back by MAC address.
