Still working on the “low storage” install prob 80188308. Note, this is not USER storage you can clear- it’s install partition. Sit tight.

Earlier today, we reported that Microsoft has fixed the ‘Error 8018830f :The update was downloaded, but couldn’t be opened’. Joe Belfiore today confirmed that the fix is out and it was a “packaging problem” with the update. However, there are another set of people who are experiencing 80188308 error. Joe today confirmed that the error is due to low storage issue in the install partition and they are still working to fix it.
