A WinOLS 47 VM is just a folder of files (.vmdk, .vmx). You can copy it to an external NVMe drive, upload it to a NAS, or clone it before attempting risky map edits. If you corrupt a calibration file or the OS crashes, you revert to a snapshot in seconds.
If you have a more specific goal or requirement in mind (e.g., integrating WinOLS with other software, optimizing VM performance for ECU tuning, etc.), providing those details could help in offering a more tailored response.
Cause: VMware changed virtual NIC MAC address.
Fix: Edit .vmx and add: ethernet0.addressType = "static" and ethernet0.address = "00:50:56:XX:YY:ZZ".
