Windows 10's fall upgrade: Yep, it's a service pack
Microsoft last week tacitly confirmed that this year's fall upgrade for Windows 10 will, in fact, be service pack-like, in effect a rerun of the May 2019 Update, aka Windows 10 1903
On Thursday, Microsoft delivered two previews to what it continues to call 19H2, a reference to the second-half upgrade in its twice-annual cadence for Windows 10. Some Insiders - the volunteer participants in the Windows 10 beta program - would get one build while others would get another.
The difference? "A subset of Insiders in the Slow ring will have features turned off by default, and another subset will have them turned on by default," wrote Dona Sarkar and Brandon LeBlanc, Microsoft employees and the public faces of Windows Insider. "We are testing the ability to ship these updates with features turned off by default so that we can then turn them on via controlled feature rollouts. This helps us gain better feedback on overall build quality."
