can you please confirm this is as expected.
Started a new Windows 2019 Eval edition (what I had handy, I assume 2022 is similar)
installed XCP-ng 8.2.2 open source guest tools.
ran windows update to get windows up to date.
Used the xenclean script to remove XCP-ng Tools tools.
Installed Citirx guest tools : Management agent, drivers version 9.4.0; told to NOT update drivers through agent (installed the older one, so as to see it update on its own)
set registry value Autoreboot to 3.
shut down
Set VM to use Windows Update in XO advanced settings.
Started VM
Ran windows update, it found latest drivers. and then -I- rebooted when told to.
Windows booted as expected. Shortly after -it- rebooted again once more
(the '3' is a Max reboot?)
Control panel, software and features still say Xen Tools 9.4.0 (old), but the individual drivers:
XenServer PV Network Device: 9.1.7.65 (old, and current)
XenServer PV Storage Host Adapter 9.1.8.79 (old)
XenServer PV Bus 9.19.105 (old)
XenServer PV Bus (C000) 9.1.11.115 (current)
XenServer PV Network Class 9.1.2.101 (old)
