Thank you so much Looks like store is working as intended but I can't update I got Code: 127.0.0.1:50034 [404]: /ClientWebService/client.asmx - No such file or directory while trying update. So can you add as option in menu or something else? Also closing window doesn't stop the server, only ctrl + c stops it.
"...itself while retaining access to the Microsoft Store" And how is that achieved (without properly configured GPOs)?
This sever requires properly configured GPO or registry values set by it. Because of that it works only with Pro and higher making it useless in some cases. Microsoft Store will not work with "Do not connect to any Windows Update Internet locations" enabled.
