While debugging the windows tests i noticed that a fair amount of time was spent copying the files from the mounted TestResultsRemote directory to the actually utilized TestResults directory.

Replacing the mount + file copy operation with an rclone copy step reduced the VM startup time by around 10 mins since the latter is optimized for bulk file transfers.

The windows defender exclusion is necessary because windows was flagging rclone as a trojan while copying files for some reason, see here
