Shabbat is not a thing you can put anywhere. It's the Jewish day of rest.
No Orthodox or conservative Jews should put 13 candles in their window. The most candles they will put in the window is 11: Eight for chanukkah, 1 shamash and 2 shabbat candles. But Shabbat candles are not normally placed in windows. In some orthodox homes young girls light candles to copy their mothers (who are also lighting candles). This might explain why there could be 13 or more; but for Jewish purposes only 11 are necessary. The rest are extra.
If you're referring to the "Sabbath mode" on certain electric appliances, we put the appliance on that mode from shortly before the day of Shabbat until after the end of Shabbat, because on our Shabbat we're not allowed to adjust appliances or directly cause a change in their operation (such as opening a refrigerator door if it will directly cause a light to go on, etc.).

Anything but a list of 39 prohibited acts. In the Talmud, tractate Shabbat, 12:1 it summarizes the spirit of the law as "one who does work on Shabbat and the work is enduring has violated shabbat." So, recreation, eating, worship, argument, all those are OK, but don't make things, plant things, harvest things, carry things (outside of your private domain), light fires, or put out fires (except to save a life). Saving someone's life on Shabbat is, of course, permitted even if it takes work.
