With a new year comes new updates for Windows 10 and Windows 10 Mobile. The updates tend to come on the second Tuesday of the month earning the nickname Patch Tuesday.
According to our sources, starting on January 12, build 10586.63 is expected for PC users and also likely those on Windows 10 Mobile. This update is a cumulative OS update bumping users from the current build 10586.36 release. No word on what is improved just yet, but there are usually general security and bug fixes. However, once Microsoft makes the news official we expect to hear more guidance.
Of course, if any last minute bugs are found the update could be delayed making the information presented here tentative.
