Blocking availability of the update to devices we know will experience issues is a key aspect of our controlled rollout approach. We decide what to block based on user impact, and blocking issues are a high priority for us to address as quickly as possible. During the time it takes to address an issue, we want to limit the number of customers exposed to that issue.
Therefore, we continue to recommend (unless you’re an advanced user who is prepared to work through some issues) that you wait until the
Windows 10 Creators Update is automatically offered to you. When your device becomes eligible for the Creators Update rollout, you’ll be prompted to make some important choices on your privacy settings before the Creators Update can install.
