Very useless article - who else buys Windows tablet on ebay from China mainland?
I bought it with Win8 couple of years ago. Now it upgraded to Win10. The GUI became in Chinese. Google has zillion pages how to change the interface language from English to other latin-letter language... not helping.
So I used OCR translator to manage with menues in Chinese.
1. Drag the side bar.
2. Click on Settings.
3. Click on Language settings.
4. Click on Region settings.
5. Click on English. I had this setting from Win8. But update lost the content.
6. Choose the middle button in expanded frame (the only non-greyed option).
7. Click on 下载语言包下载
8. This will download English language pack. Wait till the end of download and unpack (tens of minutes).
9. Reboot the computer: Win-button --> Power button (international pictogram) --> Lower option in the open menu (Restart).
Another reason to start learning Chinese.
