Windows 10 October 2018 Update (version 1809) is the messiest update released to Windows 10 since its launch in 2015. While the operating system has managed to receive a lot of criticism over the years for its updates breaking things, version 1809 was so bad that Microsoft had to officially pull it back just days after publicly releasing it. While this has in turn worked in users’ favor since the company is now considering to offer the ability to pause updates for over a month, version 1809 itself remains as unpopular as it was during the first week of its release.

Latest stats from AdDuplex confirm that many Windows 10 users are waiting for the next Windows 10 version and completely skipping over October 2018 Update. The report reveals that just 26.4 percent of Windows 10 machines have been updated to version 1809 with version 1803 (April 2018 Update aka the fastest-adopted version) still controlling over 66 percent of the market share.
