Setup Windoof in a experiment VM ================================ Install system STRICTLY WITHOUT internet connection. Stop annoying windoof auto updates. Make sure to use windoof newlines (CRLF) in the reg file: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU] "NoAutoUpdate"=dword:00000001 curl -sSD- http://10.0.2.9:80/stop-annoying-updates.reg -O After running "reg" file, we can reboot windoof with internet connection. Download/Install: - "https://learn.microsoft.com/en-us/sysinternals/downloads/sdelete" - "https://notepad-plus-plus.org/" Install needed software (Maybe: firefox, MsOffice, MsTeams, ..?). Manually trigger updates, reboot, updates, reboot, (likely some more turns ...) Configure Performance options. Disable all but screen fonts. Make sure no more updates are running. Then, I guess best is to reboot without internet access once more to cleanup the disk. Delete unused files like trashcan or downloaded installers: SDelete.exe -nobanner -z C: Shutdown win guest, then compact disc. qemu-img convert -O qcow2 input.qcow output.qcow2 Image is ready.
