Microsoft's Windows Program Manager Gabriel Aul took to Twitter today, to not only reveal some numbers on the Insider program, but also to remind those running the Windows 10 Tech Preview that they require a certain update before moving forward. Update KB3025380 (linked below) is strongly advised to be installed before Microsoft rolls out the next build of the preview.
According to the Microsoft website, KB3025380 addresses the following:
"This update includes improvements to Windows 10 Technical Preview Build 9879 that will let members of the Windows Insider Program continue to receive future released builds of Technical Preview."
Microsoft plans to roll out the next release of the preview sometime next week, so get this update installed and prepare yourself for more goodies to be fired to your PC.
