Windows Insider Preview releases to the Slow ring are few and far between, but this one is particularly notable: Build 17074, which hit the Fast ring just a week earlier, is packed with new features. This is especially true when you consider that it builds on five previous Fast ring builds that never came to the Slow ring.

“We have released Windows 10 Insider Preview Build 17074.1002 to Windows Insiders in the Slow ring,” Microsoft’s Dona Sarkar wrote in an update to the original post about build 17074 arriving for Fast ring testers.

That “.1002” bit is important, too: Microsoft previously updated build 17074 to address some problems with AMD systems.

“This build is the same as the version of Build 17074 released last week with 2 additional fixes,” Ms. Sarkar noted at the time. “We have fixed the issue causing AMD PCs to become unbootable – which means we have removed the block for AMD PCs we put in place last week. And we also fixed the issue causing certain devices to hang on the boot screen after upgrading if virtualization is enabled in the BIOS.”

To understand the changes that Slow ring testers will see in Windows 10 Insider Preview build 17074.1002, you will need to go back and review the changes that occurred in builds 17035 (November 8), 17040 (November 16), 17046 (November 22), 17063 (December 19), and 17074 (January 12). That is over two months of feature updates and additions, and a much more complete picture of what Windows 10 version 1803 will contain. So you’ve got your work set out for you.

Enjoy!
