My mother is living in a retirement community which has a draconian firewall setup. She is unable to download windows10 updates to her computer. She can access standard network ports like email, http, etc. but for example, netflix does not work there, and windows10 update is also handicapped.

Does anyone know of a way for me to keep her windows 10 computer up to date, notwithstanding this problem? This could included setting up a proxy server at my house if that will solve the problem, or manually downloading the updates through the web or ftp somehow.

Any advice welcome..
