I have a legion Y540 windows 10. I recently updated to the latest 20H2 ( not sure if am correct with the version) after that I saw a gradual drain of my laptop battery , it gives me hardly an hour over battery and i saw what was consuming this heavily and found that Windows Modules installer worker is continuously running and draining the battery.
I checked online and found out it might be trying to install updates , I tried updating and everything , the result is still the same. Oh I have already tried going to services and setting it manually and all . I am thinking is it just for me . I am planning on resetting the OS and see what will happen.
