Where does venv take pip from?

When I run pip --version I get pip 20.2.4, but when I create a new venv such as

python -m venv venv 
venv\Scripts\activate
pip --version

I suddenly get version pip 19.2.3 from the venv. I tried to search all my drives for older pip which might get used for creation of pip inside venv but I only found 20.2.4 versions.

Where does python -m venv take source for creating pip file in my venv?

NOTE: I am running on Windows as you can see by the way I active the venv.
