I was back in the US and took the opportunity to create a boot USB and re-installed the English version of Windows 10.
There was something really troubling about the pre-installed version, I kept getting this Chinese pop-up with skimpily dressed dancing girls etc. When not connected to wifi, pop-up had no ads, wh en connected, many ads. Ran McAfee and Malwarebytes, couldn't get rid of that pop-up. Now, after installing the English version, I don't have the pop-up and I feel much better.
I would like a deep scan of the laptop, wondering where to get that.
See for yourself.
