Hey @BJS56, that's rather odd mate. Updating your Windows software shouldn't have an impact on your device showing up. Sometimes with new instalments though, previous history, cookies and caches can be removed and so its just a matter of connecting them back on.
If the issue was an happening across all platforms, I would recommend having a chat to our Tech Teams over on the Optus App where they will be able to advise and assist in the best possible way.
