On Linux, Vim's clipboard support is intimately tied to X. If you want the same level of integration between WSL and the rest of Windows has you are used to in a proper Linux Box you will have to install a Windows X Server.

1. On the Linux side, install a clipboard-enabled build of Vim. The vim-gtk package is fine.

2. On the Windows side, install an X Server like VcXsrv (there are many alternatives, you are on your own to find the one that best suit your needs).

3. You generally have to edit a couple of configuration files on the Linux side for your X clients to use the right X Server. What to do exactly will depend on the X Server you choose.

4. In Vim, on the Linux side, use either "+ or "* as you would if you where on a genuine Linux box.
