You don't need to "reload" Win10. The system has recovery options of reset and restore (I think those are the names, I'm typing on the fly, not looking it up as I go). I did what I think was called a "reset" on my neighbor's computer for her when some files were corrupted by malware. The reset allowed a clean re-write of the Win10 files over the existing ones and no data was lost. The restore takes the computer back to square one and you lose all data and installed programs.
