I asked a technician in my city to fix an error on my laptop, without knowing he performed a Windows reinstall which caused all my data to be lost. I have searched for windows.old on drive C: and I can't found it, When I asked about windows.old to him, he said windows.old folder only appears if you reset the laptop, and if you reinstall Windows, all previous data will be formatted.
I've tried several data recovery applications but had no luck. Is there any other way?
