SOLVED Windows 10 - can't update

[LSeed]

I’m having trouble updating Windows 10. I tried many ways to learn from youtube, but none of them helped. I really hope someone can help me provide your professional experience to solve this problem. I haven’t used my laptop for a while, and then when I check for updates it doesn’t work, it says: "Your device is missing important security and quality fixes."
Thanks in advance.

Ren %Systemroot%\SoftwareDistribution\DataStore DataStore.bak
Ren %Systemroot%\SoftwareDistribution\Download Download.bak

Del "%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\qmgr*.dat"
Net Start bits
Net Start wuauserv
Net Start appidsvc

Restart the PC & try updating again.

And/or:
Search for services.msc & find Windows Update & ensure it is set to Automatic.
