best programs for windows?

so im getting a new windows computer v e r y soon and cant wait to use it.

only problem is that i havent used a windows computer, (except for at school), in over half a decade.

my question is, what are the best free or inexpensive programs for windows that i should get right when i boot up the computer?

(yes, i know that i will get steam and google chrome)

thanks

To anyone typing a response, please look as these images as a reference. They're the programs that I currently use on my Mac. If there are any programs similar to ones seen here that are on WIndows, write them down please!
