Modify the default copy and paste Key Binding settings of vimacs

I used the vimacs plug-in gvim, but C-y can only paste the content copied in gvim, and there is no way to paste anything other than gvim. ProgramCopy the content to the Windows clipboard.
I took a closer look at CodeTo paste the content copied from other programs to the Windows clipboard, use the key shift + insert. to paste the content copied from gvim to the clipboard, use the C-y key.
Similarly, in gvim, M-W can only copy the selected content to the gvim clipboard. In gvim, copy the selected content to the clipboard of windows, the key control + insert is required.
This setting is somewhat annoying! In most cases, after I copy the content, I paste it. The paste must be a document in gvim. I need to copy it to make it available everywhere. I was a little confused by the meticulous division of key functions like vimacs.
In order for M-W to copy the content to both gvim and Windows clipboard
Vnoremap <c-ins> "* y
Change
Vnoremap <m-W> "* y
You can.
To enable C-y to paste the latest copied content from gvim or Windows clipboard
Inoremap <s-ins> <c-r> <c-o> *
Change
Inoremap <c-y> <c-r> <c-o> *
You can.
Now, this setting is exactly the same as that in my Emacs. It is much more comfortable to use. This method has only been tested in windows, and other platforms have the opportunity to test it again.
