windows update

My computer updated windows and am unable to drag indicators into my mt4. What can I do?

If it is related to the market products (and if activations are enough) so you can delete the products from Metatrader and install it directly from Metatrader once again.
One activation will be lost because of this action (because of Windows 10 key update).
