Hi ngocminh, nice to have a Vienamese ask about mining here. To turn of window 10 update, you go step by step as following:
In RUN type services.msc, the services page will be open
Search for Windows Update
Click Stop if status is Live or Checking/Running
Select Disabled on Startup type
Apply & Restart
Do it again and make sure that it is disabled
Also if you want you can disable more services..
This is old info and no longer works with newer builds of Windows 10. The fall 2017 build and newer will simply re-enable the service after a few days or a reboot. There currently is no easy way to stop windows 10 from updating itself. It requires registry hacks and I've only successfully been able to stop it on one rig, but I don't know which of the 100 changes I made actually did it.
