So we could expect that the company plans to release a new Windows 10 Insider Preview Build with new features and fixes for Fast Ring Insiders on Thursday. There are also reports coming in that as announced earlier Windows 10 Creators Update will not be released in March 2017 as the company confirms it still has lot of work to complete before officially releasing the Update to general public.
Hence now the Creators Update will be released in the month of April 2017. The Creators Update is expected to bring some new and cool features which the company is currently working and the Insiders on Fast Ring would be the first people who would be testing the new features to be released with the Creators update now expected to release in the month of April 2017.
