Company is working on a fix
The last few days have been rather hectic in terms of Insider Preview releases, with those in the Windows Insider program’s so-called Fast ring getting hit by as many as three builds in a span of four days. This is probably to be expected as Microsoft races to fix bugs and fine-tune features ahead of Windows 10’s launch at the end of the month, but this frenetic pace seems to have its own problems.
Turns out some people are having trouble activating builds 10519 and 10162 — the latest two official releases. Writing on Microsoft’s Answers site on Friday, one such Windows Insider program member complained about his inability to get past the activation process despite having tried doing so around 20 times. In its response, Microsoft assured the user that the problem was known to the developers and they were working on fixing it.
Here is Microsoft’s response in full: “We are doing some testing and work on the Activation process. That message is expected and we hope it will go away in the next day. When we have the service back up and running, it should attempt to activate automatically. Until then you can ignore it because I believe other than the UI showing its not activated, its not affecting any other use of the system.”
