On the eve of the Windows 10 Fall Creators Update release, Microsoft is touting the quality and reliability of the previous version, the Creators Update.

“The Windows 10 Creators Update is the best version of Windows 10 ever,” Microsoft director John Cable writes. “What makes Windows 10 Creators Update the best version of Windows 10 ever? Quality. Our dedicated focus on customer obsession – listening and responding to user and partner feedback – are key to the quality improvements in Windows 10.”

Microsoft is promoting the following advances in the Windows 10 Creators Update:

• Battery life improvements. A performance power slider feature lets users easily switch between battery saver and best performance mode levels, resulting in an average savings of 5 percent battery life. The Movies & TV app is more efficient, resulting in a 5 percent battery life improvement while offline (and 2.5 percent while streaming). Improvements in Microsoft Edge contributed a 17 percent improvement in battery life across every-day tasks, Microsoft says. And the Mail app is now 40 percent more efficient than it was in the November (2015) Update.
• Performance improvements. Compared to the Anniversary Update (mid-2016), the Creators Update has provided a number of performance improvements: 13 percent faster booting, 18 percent faster log-ins, 30 percent faster Windows Hello Facial recognition, 53 percent faster browsing with Microsoft Edge, a faster Start Menu, faster Windows Search, and more.
• Better reliability. In the Creators Update, Microsoft is seeing an 18 percent reduction in “users hitting certain system stability issues versus earlier versions of Windows 10.” And there has been a 39 percent reduction in “operating system and driver stability issues between the Anniversary Update and Creators Update.”
• Reduced customer support volumes. According to data that does not include the time period before the incredibly buggy Anniversary Update, it looks like Windows 10 customer support volume has “diminished significantly”. But there are no hard numbers here. And I believe that Windows 10 was actually more reliable before the Anniversary Update as well.

Frankly, this whole thing is rather curious, both for its timing and because it leaves out any data from before the Anniversary Update. Rather than belabor the point, I’ll just note that this is what Microsoft provided. You can come to your own conclusions, but I don’t quite understand why they are revealing this now.
