And what do you define as “extra”? FYI, Windows Explorer is an “app from msft”, Windows Desktop Manager is an “app from msft”, and pretty much everything that isn’t the kernel is an “app from msft”.
Also, those Windows Store apps (Minecraft, Candy Crush, etc.) are not actually pre-installed. You just have to unpin them from your start menu if you don’t like them. If you try to click them, you will see it only then begins to download an install them.
Gas stations don’t sell USB sticks over here, but I’ve installed Windows 10 from a USB stick that literally costs less than $5 (sale price, but it’s still the cheapest thing you can get even without sales). It took way too long to copy the files into the USB stick, but during the installation itself, it was hardly noticeable. I still installed it in less than 1h, just like I always do on this tablet PC.
It’s not that big. The 64bit image is about 4.5GB (fits in a DVD). Nowadays, that is in no way “big stuff”.
You make it sound like it’s old… but it’s actually brand new, lol… I use sticks that are 5 years old or more, seriously, these things never get old unless you physically break them.
