I believe you can check to is if you copy has been activated

Open Start Settings app Update and Security.

Select Activation, in the left panel. Here you will see the activation
status.

I think if I were in this situation, the first thing I would do is to
deleted all folders in the My Documents folder. This is all of the
data put on by the previous user. Next I would look in the primary C:
folder and remove any user data folders. (I have one called personal
data, that has folders for software, pictures, etc.)

I would then delete all files in the Temp folders. There is one in the
Windows folder, and in each of the folders in C:/User/Username/Appdata.

I would then from the C: properties window run a disk Cleanup, followed
by the Check. I would then do a defrag

This should free up a significant amount of disk space and you should
have an organized error free disk.

I would then upgrade to Creator Edition. This will check your windows
10 activation status. If you have installation problems you can delete
the files in SoftareDistribution in the Windows directory. You may not
be able to delete all of the files in the Datastore folder, but the
system will make things right.

If all of this happens with no errors, I would run the computer for a
period to ensure everything is working correctly then go ahead and do a
clean install of the current Windows 10.

While this will take a little longer that doing a clean install first,
in this way you will know the computer is working, without the
consideration of any problems in the clean install with vendor specific
drivers, etc.

You drivers for the HP should be on a drive called DRecovery)
