Microsoft couple of days ago released the First Cumulative Build for Windows 10 Creators update for Insiders in the Fast Ring. The company had fixed a bug which prevented Anniversary Update users not to upgrade to the latest Insider Preview Build.
The Redmond Giant has now released the same Cumulative Update build to the Insiders in the Slow Ring yesterday. The Build is currently rolling out and should be available for download for all Insiders in the Slow ring.
The Insider Build 15063.2 has been confirmed as the RTM build which will be rolling out to all PC users of Windows 10 on April 11 and then it would be released to Mobile users of Widows 10 at a later date.
The Insiders in Release Preview Ring could well expect the RTM Build 15063.2 to be released to them in this week. If users on Slow Ring haven’t yet downloaded the latest Build, they can do so by going to Settings>Phone Update>Check for Updates.
