What’s up with Windows Update after v. 1809 installs?


Is it okay to use the “Check for Updates” button in Windows 10 v.1809?


 As of Windows 10 v.1809, for the regular end-user it is now recommended to wait until Windows Updates are offered so that the updates are stable.

Here’s why:

“Patch Tuesday” or Update Tuesday updates are published on the second Tuesday of each month. They are known as the “B” release .  They are the regular monthly releases that include both new security fixes and previously released security and non-security fixes. These updates have been fully tested and are expected to be stable.


Optional non-security  validated, production-quality “C” and “D” updates are released at Week 3 and 4 each month. They are for commercial and advanced users for testing fixes to be included in the next Tuesday update. Advanced users can obtain the “C” and “D” releases by navigating to Settings > Update & Security > Windows Update and clicking the “Check for updates” box.


Bottom line: If you use “Check for Updates” you may be offered “C” or “D” updates. Unless you are an advanced user and are interested in testing, wait for the regular “Patch Tuesday” or do it during Week 2 for “B” fixes.
