Windows 10 upgrade: Survey finds half of users experience problems

"Facts are stubborn things," John Adams once famously observed.

More than two centuries later, those words still ring true, especially with this troubling caveat behind them: Whoever controls the underlying data can all too easily influence the resulting "facts."

And if the data is inaccurate or incomplete, facts go completely out the window.

This month's case in point is a two-week-old story that has not aged well, frankly.

A flurry of headlines at the end of May reported that Microsoft's latest Windows 10 feature update had been installed by half of all eligible PCs in less than a month.

That number was not even close to accurate, and the actual adoption rate was probably less than half of what that estimate claimed.

The facts were bad because they were based on questionable data from a small Windows app cross-promotion network called AdDuplex. As I noted at the time, "a closer look suggests that the data behind that report is, to put it charitably, weak."[1]

Today, thanks to a bit of chest-thumping from Microsoft[2], we have some better data. "The April 2018 Update is officially the fastest version of Windows 10 to reach 250 million devices, achieving that mark in less than half the time it took the Fall Creators Update," officials said in a blog post yesterday.

That's impressively fast: a pace of 5-6 million devices per day and roughly 40 million PCs per week. At that
