Why use Hotmail? It's a total joke anyway.
GMX is far better. Simply set up a new account here:
https://www.gmx.co.uk/
Then use the Mail Collector facility to get mail from your Hotmail account automatically forwwared to your GMX one (so you'll only have to log into one account and you won't miss anything sent to your old address).
Once everyone whom you actually want to receive mail from is aware of your new address you can simply disable the Mail Collector and just use your GMX address.
