The Windows 10 Fall Creators Update is now installed on more than 90 percent of Windows 10 PCs, according to AdDuplex's latest monthly report on the Windows ecosystem. This comes just weeks ahead of when Microsoft is expected to ship its next big feature update in April. For comparison, the Creators Update only managed to reach 72 percent coverage during a similar period before the Fall Creators Update's launch.

The Fall Creators Update has seen a pretty rapid release compared to its predecessors. "Fall Creators Update is undeniably the fastest spreading update in a long time," the AdDuplex reports. The update reached full availability in early January, helping it to jump 20 percentage points between December and January, hitting 75 percent coverage. Growth slowed a bit after, but still maintained a 10 percent boost to 85 percent coverage in February.

As for past releases, March saw their share shrink by quite a bit as well. The Windows 10 Creators Update is now a 4.3 percent, while the Anniversary Update comes in at 3.6 percent. Below that are Windows 10 versions 1511 and 1507, each at 0.8 percent and 0.5 percent, respectively.

AdDuplex also offers an interesting look at PC OEM share. HP remains in the lead, keeping hold of a share of 26.1 percent of active Windows 10 PCs. Dell follows up with 17.3 percent, and Lenovo comes in at a 12.6 percent share. Asus and Acer round out the top five with 8.7 percent and 8.6 percent each. Toshiba (4.4 percent), Microsoft (2.5 percent), Samsung (1.8 percent), and MSI (1.6 percent) all come in below five percent.
