do you have a reason to switch to 285? AFAIU, 271 works well, and there might be some issues with 285 https://pve.proxmox.com/wiki/Windows_VirtIO_Drivers#virtio-win_Releases
I had a problem with the qemu agent and SQL server backup. However, it seems that the problem was elsewhere. But when I started solving it, I thought that upgrading virtio would not harm anything, and then the problem appeared that the agent cannot be upgraded or uninstalled. That's why I'm asking the more experienced ones here on the forum.
