There are a couple of ways that you could have refreshed Windows. How did you do it?
If during the recovery, you selected Refresh your PC without affecting your files, then your files should have been saved in
C:\Windows.oldIf you selected Remove everything and reinstall Windows, then your files were deleted. At best, you could try using data-recovery software to attempt to get at least some of them back (which may or may not work depending on numerous factors specific to your system and usage).
