I am also in the Insider Preview Program for Windows 10, I am in the fast lane. The reason why we are testing beta software for Microsoft is to find and report any problems that we find. I believe that going to Bleeping Computer to find a fix for a problem that you find in an Insiders build is an inappropriate avenue. You need to use the Feedback Hub and the appropriate Insiders forums to report these issues, not try to find a correction for your system that does not help Microsoft to detect and correct the issue for the entire program.
When we signed up to test beta software for Microsoft we knew full well that there could be and would be problems. Our job is not to try to correct the problem but to report the problem. Dona and her team are working very hard right now since the date for public release has already announced and it is quickly approaching. There might be 10 or 15 new builds coming in the next couple of weeks so that we can test every issue for Microsoft, but all we can do as Insiders is prepare, test and report.
Have fun with the program or just return to the retail build. Myself I oscillate between the Insiders program and a retail version when ever the whim hits me. I just did a clean install of version 1709 build 16288.1 from a homemade ISO that I created using the canonical UUP files
