This month, contrary to most months, there was no preview update. This was almost certainly due to the fact that the team was home for the holiday break. As always, Patch Tuesday comes with a relatively short changelog, simply rehashing everything in the preview update. Since there was no preview update this month, you might have expected it to be a bit longer.
These are the highlights of update :
- Updates a known issue that affects Japanese Input Method Editors (IME). Text you enter might appear out of order or the text cursor might move unexpectedly in apps that use the multibyte character set (MBCS).
- Updates security for your Windows operating system.
The full list of fixes is below :
- In apps that use the multibyte character set (MBCS), the text may appear out of order or the text cursor may move unexpectedly when using a Japanese Input Method Editor (IME). This issue affects the Microsoft Japanese IME and third-party Japanese IMEs.
The patch is mandatory, as it is with all Patch Tuesday updates. You can get it now by checking Windows Update for updates or installing it manually, but if you don't, it will still install automatically at some point.
There will be another preview update later in the month, which are often referred to as 'C' and 'D' week updates. Unlike Patch Tuesday updates, these are not optional. When they show up in Windows Update, they don't get installed unless you explicitly request them.
