I bought my laptop in USA but recently had to do a clean install of Windows 10.
My keyboard began having serious problems, not registering a character when pressing a key, or registering multiple characters, all of an intermittent nature. I took the machine to the local dealership here in Kunming. They said it was a system problem, not a mechanical problem. They fixed it (for free thank you, as it had just passed out of warranty) by installing new system, which meant Windows 10 Chinese version. This is a one-language version, not possible to add or convert to English.
It quickly became evident that I could not live with an operating system in Chinese characters.
So, time to follow the links provided by an earlier poster on this thread. Biggest difficulty was that my machine can not boot from external media like a thumb drive, a limitation of the low level UEFI hardware. But I found a solution on the internet, basically just had to copy the windows.iso file directly onto my machine and run setup.exe.
Took ten days to fix, including time spent at dealership. So glad I hung on to my previous, now 5-year old laptop, for internet research and to compare English-language screen to Chinese-hanzi screen.
Whew, huge relief now that I have a working machine again.
