Windows 10 is still in development right now, and a new build included in the Technical Preview channel is only expected to launch next month, so Microsoft has more time to fix bugs and issues in the existing 9879 version.

One of the problems that Microsoft is trying to fix these days is what the company calls “dirty shutdowns,” an issue that raises a few more problems than all the others because it doesn’t allow engineers to collect data on what causes it.

Basically, a dirty shutdown is a spontaneous system restart without a blue screen of death, which means that no crash dump is created, so it makes it really difficult to debug.

Gabriel Aul, head of the Windows Insider program, said in a tweet that Microsoft was aware of this problem and was trying to find a way to collect data on this particular problem, especially because some users had already reported similar issues on their existing Windows 10 installations.
