Windows 10 version 1803 —also known as the April 2018 Update— is the fastest spreading Windows 10 update of all time, according to third-party telemetry data released last week.
Over 50% of all Windows 10 PCs now run Microsoft's latest Windows 10 version, according to a report from AdDuplex, an advertising company that collected statistics from around 5,000 Windows Store apps running AdDuplex SDK.
Since Microsoft has always stayed mum on Windows 10 statistics, the AdDuplex report is the best insight we're going to get about the success of the latest Windows 10 version.
According to this report, it took the April 2018 Update less than a month to reach the 50% mark, compared to last year's Fall Creators Update, which needed three months to reach 50% deployment.
The overall trend is that Microsoft is getting better and better at rolling out its major Windows 10 updates.
Furthermore, 43% of all Windows 10 users aren't that far behind, running the Fall Creators Update, and being a click away from running the latest Windows 10 version.
All in all, this means that the vast majority of Windows 10 users are running one of the last two Windows 10 updates, and should be, in theory, up-to-date with most security patches as well.
But, to be honest, the AdDuplex report is also surprising because the Windows 10 April 2018 Update appears to be a success, despite beeing plagued by bad press for the past two months.
The April 2018 Update was originally planned for release in the second week of the month but the official rollout was delayed until the last day of the month due to lingering BSOD issues.
The bad press continued after the official release as well, as Windows 10 users reported issues with Intel and Toshiba SSDs (now fixed), issues on systems with Avast installations (now fixed), and later issues of forced updates to the latest version, the latter of which Microsoft is now investigating.
