Microsoft has re-released its second major update for Windows 8.1, also known as the August Update (Update 2 for those keeping track). The update originally launched on August 12, but was pulled a few days later due to a few bugs which rendered 0.01% of users unable to use their PC's properly. Either way, the update is back in Windows Update with all bugs squashed, so get updating!
Microsoft said in its official statement:
UPDATE September 2nd: On August 15th, as soon as we became aware of a small number of customers experiencing problems with the August 2014 update rollup for Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2 (KB2975719), we immediately investigated and pulled the problematic update making it unavailable to download. Today, we are re-releasing this update with fixes for these known issues.
The update can be grabbed from Windows Update right now. If it hasn't shown up in Windows Update yet, give it time as the rollout may have to hit your area first. Will you be updating to the August Update? Considering this update isn't a must-have, many consumers won't bother updating.
Those who installed the August Update when it first launched were instructed to remove the update, and we assume removing the update will make things easier for you when installing the newer version of the August Update.
