Windows 10 May 2020 Update rolls out with caution.
Windows 10 OS Worldwide (PCs)
May 2020 Update (2004) adds about 4.6% to its share this month. This is less than the 7% it gained in its debut month.
Close to 134,000 Windows 10 PCs were surveyed.
Windows 10 OS Worldwide History (PCs)
As is now common, the growth in the latest update's numbers comes primarily not from its predecessor but a version before that.
Note: we don't have the data for the initial rollout of the first update to Windows 10 (1511, also known as Threshold 2). So it's a straight line from 0 to the first data point we have on August 22nd, 2016.
