 NOTE: When Vim exits the shape for Normal mode will remain.  The shape from
 before Vim started will not be restored.

+For Windows Terminal you can use something like this: >
+    " Note: This should be set after `set termguicolors` or `set t_Co=256`.
+    if &term =~ 'xterm' || &term == 'win32'
+	" Use DECSCUSR escape sequences
+	let &t_SI = "\e[5 q"    " blink bar
+	let &t_SR = "\e[3 q"    " blink underline
+	let &t_EI = "\e[1 q"    " blink block
+	let &t_ti ..= "\e[1 q"   " blink block
+	let &t_te ..= "\e[0 q"   " default (depends on terminal, normally blink block)
+    endif
