It's Tuesday January 14, the first Microsoft Patch Tuesday of 2014. As has been the case with most of the recent Patch Tuesdays, Microsoft is patching its Windows 8.X Surface tablets.

As part of today's patch bundle, Microsoft is issuing a fix to its first-generation Intel-based Surface Pro firmware. The Surface Pro fix will be available "later today" for download from Windows Update. This fix addresses issues users have had with both the Type Cover 2 and Touch Cover 2 when running Windows 8.0 on Surface Pros.

What about the Surface Pro 2 firmware patch some were expecting to be out today? Microsoft pulled the December Surface Pro 2 update from its download site after a firmware glitch caused a number of those attempting to install the December Surface Pro 2 update to encounter serious battery-life problems. The December update for Surface Pro 2 included a patch that was originally designed to improve Surface Cover interaction including power-saving sleep functionality.

I've asked Microsoft about the Surface Pro 2 firmware update. I'm hearing from my sources that the fix for that one is still in the works.

A Microsoft spokesperson said: "Our customers’ experiences are very important to us and we are working hard to release an update package as soon as possible."

There may be more Surface updates from Microsoft today for its other device models. If there are, none are listed on Microsoft's Surface Update History pages at the moment.

In terms of non-Surface-specific updates, Microsoft patched four non-critical security issues today. The list of non-security-centric patches is longer , and includes a number of Windows 8.x ones.

Microsoft issued a fix for its ARM-based Surface 2s earlier this month which remedied a rogue Bitlocker prompt issue .
