Inspiron 3668 restoring Win10 to previous state

My computer crashed, so I went through the SupportAssist program, did a backup of the hard drive, and reinstalled Win10.  I cannot get SupportAssist to reload the backup information that it created.  I have a folder on my HDD with a bunch of .mig files which I have read are used by USMT to reload information, but I cant figure out how to reload the info.  Any help would be greatly appreciated!
