What edition and version of Windows is installed?
Source?
Windows' default configuration is to install updates as the updates become available for release.
However those updates can be stopped or delayed to a certain extent.
Check two things:
1) "WIN" + "I" > Update & Security > Windows Update
How is Windows currently configured?
There is also, or should be a "Check for Updates" option.
2) In the "Type here to search" box type "View your Update history"
Any listing of failed or problem updates?
As a side note if you are not using a legal copy of Windows and/or are getting/trying to get updates from non-Microsoft websites then it is just a matter of time until the system will crash due to buggy/corrupted code. Or get infected with some nasty virus or malware. Or hacked to where your personal information is exposed.
Maybe that has already happened......
