In a blog post in the Windows blog, John Cable, the Director of Program Management, Windows Servicing and Delivery at Microsoft, advised Windows 10 users to refrain from manually installing the Windows 10 Creators Update unless they are advanced users who can handle fixing some issues that may arise from installing the update.
According to Cable, the warning is based on the feedback from the millions of users who have installed the update. Cable also explained in the his post that they have slowed down the roll out of the update because of the issues that were pointed out by those who have experienced having the update.
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. For example, our feedback process identified a Bluetooth accessory connectivity issue with PCs that use a specific series of Broadcom radios, ultimately resulting in devices not reconnecting as expected. Once identified, we posted this issue to our Windows community forum, provided user guidance on troubleshooting, and blocked additional devices with these specific Bluetooth radios from updating. Once a solution is available, we will update our forum post and remove the block.
Actually, this is not a problem for those who are not into manually installing new updates. The warning is for those who like to go out and search and download and manually install updates to try them out.
When Microsoft fixes the issues in the Windows 10 Creators update they will release it for everyone and the update will automatically install. If you will experience problems with the new updates in the future you can roll back and uninstall it, just follow this instruction.
