Upgrading From x240 to x13

Hi guys, I recently upgraded from an x240 to an x13, but have a few questions:

1. After 7 years on the x240, windows 10 feels... different. I know it's not a question lol but any tips? I'm coming from windows 8, I think. 2. Is there any way to quickly transfer files and programs like you can do wihen changing phones? 3. Due to the pandemic, I had to buy the unit directly from China. The system font is different from what I'm used to. (IE, when installing stuff like iTunes, the font in the dialog boxes seem to be Simsun). Is there any way to change it?

Thanks in advance for any help!
