Recently I got a new PC with Windows, and it could resize its partition without problems. You can do it even with Powershell. I don’t know how dangerous it is, but with the whole “copying user data” I would hope that the installer would advise users to create a full backup anyway.
I don’t know how you ended up on a page for a Taiwanese marketplace and didn’t realise it.
But on the other hand the official customs page doesn’t have anything about animal products.
You cannot plug in any old power source, but you can with special micro inverters.
Oh, thanks, now I see.
