Sysprep and Windows (Server)

[kosta88]

Hello,
I noticed that I cannot sysprep a finished server 2025, my guess is that after I install the virtIO drivers, if I sysprep, it will delete those, and make disk inaccessible.
Is the only way to use a disk that is not virtio dependable, or are there other solutions? Maybe inserting drivers into the ISO, would that make it permanent?
Thanks

I've used sysprep with Windows 10/11 and Server 2016 to 2022 on Proxmox without problems
Did you add the driver in early setup as described in the wiki?
How did you start sysprep? At OOBE with ctrl+shift+f3
