With Microsoft remaining silent on the interminable delays to the Windows 10 April 2018 Update, its predecessor has set a new usage milestone. The Fall Creators Update is now being used on over 92 percent of all Windows 10 PCs.

This is according to AdDuplex, the largest cross-promotion network for Windows apps.

The Fall Creators Update had been skyrocketing in recent months, but the new tally, 92.1 percent, is a new apex. In March, this release had hit 90.4 percent, after reaching 85 percent of all Windows 10 PCs in use in February.

Meanwhile, the next major feature update for Windows 10, the April 2018 Update, has been delayed repeatedly, and mysteriously: Microsoft has briefly mentioned what sounds like some serious reliability issues that it has fixed. And last week, it shipped the new RTM build to Slow ring and Release Preview ring testers, indicating that the end is near.

But the April 2018 Update’s feature set was finalized in March, and Microsoft had originally expected to start shipping it publicly by mid-April. Now it appears that it won’t see the light of day until May. April Fools!

AdDuplex also looked at Surface PC usage this month, but things haven’t really changed month-over-month. Surface Laptop usage, at just 2.3 percent, is still suspiciously low, and below the usage of Surface Pro 1, Surface Pro 2, and Surface Book. And Surface Pro 4, with 34 percent of all Surface PCs in use, is still the most successful model so far.
