How to connect mouse to tablet via OTG in WinPE?

Question

Windows

Good day! I have a Chinese tablet with Windows 10 EN on board. I want to put the Russian assembly without any frills on a clean one, because the Windows that originally stood were dirty. I regretted it 100 times, but there is no way back... :)
What I have already tried:

• Write Windows to a USB flash drive and boot from it via UEFI (or its emulation, xs). It loaded successfully, but it did not see the mouse through OTG or the touchscreen.
  
• Run the installation from under the old Windows. It all ended with the fact that due to lack of space, I deleted a lot of files and the normal operation of Windows is now impossible. It loads, but neither the browser, nor even the start-up, open anymore.
  
• Write WinPE to a USB flash drive, boot from it. But there is also no mouse, no keyboard (there is a micro-usb keyboard), no touchscreen.
  

What do you advise, experts?

Answer 1

You need to find drivers for the mouse, touchscreen, and all that. If you can’t find them on the Internet, then copy them from the old Windows (if it is still alive).
