Set false in specific column to all rows

Question

I have a table with the following columns:

ID    Name 
1     test1
2     test2

Now I added new column IsConfirmed. And this column contain null in all rows.

ID    Name   IsConfirmed
1     test1     null
2     test2     null

How can I set false to IsConfirmed column to all rows in the table using T-SQL?

Thanks
