I  reinstalled my Windows 1o after the registry corrupted (and I did not realise there might have been a way to install it again over the top of my old version installation possibly via boot up as no way Windows would open anything ). I found my Windows Mail programme no longer accepted my email accounts or would do anything. In dpesration I uninstalled it, hoping top reinstall, but nothing will install or find the Windows 10 email. Can you advise?

I can only access my email via my old computer and not my more modern one.
