Windows 10 recovery without local administrator [duplicate]

I'm not 100% sure if Windows 10 recovery drives are machine related so I'm not sure if it will help at all, but you can try to repair computer using Windows 10 installer. Just click Repair your computer instead of Install now.

If that fails too, you can install Windows selecting Custom: Install Windows only (advanced). If you just select drive where you had your previous Windows installed, it will move Windows folder to Windows.old and leave rest of your data.

I've tried this and it works, but if you are really paranoid you can try any Linux LiveCD (for example Ubuntu). Without any installation you can try this OS and you will be able to browse files on your hard drive.
