Hello, A friend of mine needs to reinstall his Windows 10 OS after a hard-drive failure. It was installed on a laptop that previously had a Windows 7 Home OEM pre-installed on it and upgraded afterwards to the corresponding W10 edition while it was free. Do the ISOs available here or through the official downloader will support that OEM licence?
All 10 Multiple Editions/client iso's are OEMRET, they can use the OEM : DM bioskey for activation but not the slic from 7. Once a HWID is established on the hardware you can reinstall the corresponding windows 10 and it will use the HWID for activation (just skip at the questions for keys).
