I have in my CPU dual core with 4 GM RAM and working with Windows 10. The system updated till 16232. Afterwards it is giving trouble. Not at all updating. When I tried to troubleshoot, it clears something and starting to download the next version, but stops with no updates are available. I have one laptop with i3 processor, and 8 GB RAM. There it is updated already.

I have tried to use recovery and go back to previous build. I have not deleted anything, but still the system says it cant go back.

Can someone try to help me in this regard please
