It may not be Patch Tuesday, but that doesn’t mean there aren’t new Windows 10 cumulative updates to be installed. Microsoft has begun rolling out a number of updates to several Windows 10 versions. Today’s updates aren’t available for the latest October 2018 Update. However, they are available for the most-used Windows 10 version, the April 2018 Update, along with the Fall Creators Update (1709) and the Creators Update (1703).

Today’s Windows 10 cumulative update addresses several issues. However, they haven’t fixed any of the problems that previous cumulative updates brought in, including the SqlConnection and Start menu related bugs.
