Users had been complaining about excessively fast battery drains since the Dec. 10 update. Some of that could be seen in the linked thread, where users said that their tablets would spontaneously wake up.
In our own experience, we would see the tablet burn through most of its battery overnight, and awake to find it extremely hot. We haven't personally seen any of the other issues expressed in multiple forums threads.\
Microsoft said the following:
To ensure the best experience for our customers during the holiday season, we have taken steps to remove the update for Surface Pro 2 that was previously published through Windows Update on December 10th, 2013. We are working to release an alternative update package after the holidays.The company did not give users already affected by the issues any workarounds or advice.
It's possible, though the System Backup utility on the device, to go back to an exact image prior to the firmware update, and that is a possibility. Replies to the announcement centered around "when" as well as displeasure that Microsoft is waiting until after the holidays, rather than trying to correct the problem ASAP.
Naturally, we admit that the company must ensure this upgrade, unlike the other, is bulletproof. However, strolling through the forum one can see extreme displeasure at how Microsoft, which controls both the hardware and software of an installation for once, seemingly cannot "get it right" on its own system.
