How to change rospack cache directory after install on Windows 10

edit

I follow this tutorial to install ROS for windows, I also manually install vcpkg to finish the install like explained here.

Rospack has some problems creating cache. It is not using the cache directory located in C:\Users\user_name\.ros

c:\catkin_ws>rospack profile
[rospack] Warning: cannot create rospack cache directory W:\.ros: boost::filesystem::create_directory: Le chemin dÆaccÞs spÚcifiÚ est introuvable: "W:\.ros"

Are they any solution to solve this issue ?
