Win10 updates stuck on "fix issues" - low drive space

I just got an HP Stream back from HP, with a replacement warranty MB. They gave me the 1703 edition of Win10, so there's been a lot of updating. After a bunch of it, the machine is now up to the 1803 base.

The unit has only a 32GB eMMC, with some 28 usable, so it began getting tight as the updates continued. So I did a disk cleanup and I uninstalled MS Office, which alone runs well over 1 GB. With all that done I have some 7GB free space.

Still, Updates were claiming not enough space. Even after rebooting. Even after running Updates Troubleshooter in Admin mode.

So I don't know what else one does to get the message to WU that there is enough space to work with.

Evidently the Windows Updates troubleshooter is troubleshooter lite. I did a full updates reset and the problem is solved, plus I gained a lot of free drive space.
