However, Dev Channel Insiders may run into an error when trying to update to this latest build:

Some Insiders may encounter an error (an 800F0823 error is shown under update history) trying to install this Cumulative Update. A subsequent retry of installing this Cumulative Update is expected to complete successfully.
