it seems to be that Win10 version is Chinese version and will always be displayed in chinese... You'll need to buy either Pro version or english version of the license...

You can buy from any retailers on the market... Cheap cheap or expensive, up to you...

If you need back the Mi apps on that laptop, there's also guides to do it...

Good news is, win10 pro volume activated copy is only RM60.
If you don't need COA sticker and this laptop of yours won't be audited by your company.
Bad news is , branded laptop comes with backup image. I'm not sure about mi laptop. Usually it's for users who accidentally cause their windows to be corrupted to be able to reset back to it's original state without reinstalling drivers and went through all the troublesome methods.

You Mr Prime Minister la.. Shud paham..
Coa sticker Macam tulen sticker. Ur pc home use or biznes?
Use at home juz buy those volume activated type.
If this laptop is a company asset and needs to be audit,  then u must find alternative solution from the one I suggest.
