  Dim sheet1 As Worksheet
  Dim sheet2 As Worksheet
  Dim range1 As Range
  Dim range2 As Range
  
  Set file1 = Workbooks.Open("file1.xlsx")
  Set file2 = Workbooks.Open("file2.xlsx")
  Set sheet1 = file1.Sheets("Sheet1")
  Set sheet2 = file2.Sheets("Sheet1")
  Set range1 = sheet1.Range("A1:E10")
  Set range2 = sheet2.Range("A1:E10")
  
  For Each cell In range1
    If cell.Value <> range2.Cells(cell.Row, cell.Column).Value Then
      cell.Interior.ColorIndex = 6
    End If
  Next cell
End Sub

Save the module.
Run the script.
