Windows To Go was discontinued back in 2019 so it’s not really something that has been maintained or updated for a long time

Apps like Rufus (Windows only) are still able to create that sort of boot USB but it’s sort of a non supported feature, wouldn’t be surprised if it just stops working one day.
On Linux Ventoy is often used for this - it does have a persistence plugin but not for Windows https://www.ventoy.net/en/plugin_persistence.html
I haven’t tested this idea, but maybe you can run a Windows VM within Linux, enable USB in it, download Rufus in it, then you can create your non-official Windows To Go boot disk that way? Could be something to try if you never find another solution.






Just curious was this a Tuta paid account, or a free one?
Tuta is very strict with the free accounts and flag them for all sorts of reasons. They take their time to “approve” free accounts just to be able to use them. And on top of that they might nuke your account anyway if they think it is being used for spam/illegal activity/whatever or they think it’s not being used.
But I thought those are just issues with their free accounts, presumably their paid accounts don’t get flagged for those things… or so I thought.
Also to echo the other comments - best to buy and own your own domain for your email, that way it doesn’t matter where the email is being hosted in case you need to switch email providers.
