Microsoft is expected to add another cumulative patch to the Windows 10 desktop OS according to sources familiar with the matter



From Windows Central:

The update will bump the OS to 10586.71 up from the current 10586.63 released on January 12. The Windows Update is scheduled tentatively for Tuesday, January 26 aka 'Patch Tuesday'. Like all OS patches and updates, any last minute issues could halt or delay the release. There is no immediate word on what, if anything is new, but like previous updates this will likely address bugs and general OS optimizations for those on the desktop PCs, Surface, laptops and more. More information about the cumulative update will probably come forward when Microsoft release them to the public, but no new features are expected. As usual, there will likely be a small flood of updates to Windows core apps like Mail, Messaging and more following the patches.

  Windows 10 build 10586.71 update due this Tuesday, may come to Mobile Insiders too
