An astonishing new report from AdDuplex shows that the Windows 10 April 2018 Update has rolled out at a historically fast rate. What game is Microsoft playing here?

“The April 2018 Update managed to reach 50 percent of Windows 10 PCs in just one month,” AdDuplex notes in its most recent report. “Windows 10 version 1803 is the fastest-spreading Windows 10 update by far. It took Fall Creators Update twice as long to cross the 50 percent line, and Creators Update was under 50 percent for about 3 months.”

So there you go: As promised last week on Windows Weekly, we’d soon get the data to prove that Microsoft is spewing this update out at an unprecedented rate. Why they are doing so is unclear, given the many problems that users have had with this update. (Not to mention the internal issues that delayed the original release.) But there it is, even worse than I had expected. Much worse. Irresponsibly worse.

As for other data in this month’s report, a few things stand out:

Most modern Surface PCs are ahead of the average. “Newer Surface models are beating the global average, when it comes to the April 2018 Update, while older ones are lagging behind,” AdDuplex notes. “Surface Laptop is a notable exception with only 37.3 percent.”

Dell, Microsoft, and MSI are outpacing other PCs makers when it comes to deploying the update. “Acer and Toshiba are notably behind the global average, AdDuplex says.

As a reminder, AdDuplex is a leading independent ad network reaching hundreds of thousands of Windows 10 users every day.
