They are not part of Patch Tuesday, don’t include security fixes, and are flagged as optional updates on all systems

Microsoft rolled out this month’s Patch Tuesday updates last week, but the company is now gearing up for another important rollout that’s scheduled to go live tomorrow.

This time, Microsoft will be rolling out a total of 34 non-security updates for Windows, most of which would resolve issues with the operating system, improve performance and reliability.

But as Woody Leonhard of Infoworld points out today, some of the updates scheduled to launch tomorrow are expected to bring some very important fixes for Windows users, including a few that are developed to address problems with Wi-Fi connections.

Old updates being re-issued

Microsoft hasn’t provided a reason for this, but it appears that the company has started re-issuing old updates these days, most likely with few improvements, to address problems that it has recently found in desktop operating systems.

For example, KB3033446, which is actually one of the patches scheduled to launch tomorrow, was first rolled out on March 10 as part of the Patch Tuesday release and addresses “Wi-Fi connectivity issues or poor performance on CHT platform computers in Windows 8.1.”

KB3037924 and KB3038002 were both released on March 10 as well and come to fix an error blocking you from creating system image backup to Blu-ray media in Windows and to work with UHS-3 cards on a Surface tablet, respectively.

As usual, IT administrators must prepare for this new batch of updates and it’s worth knowing that some might require a reboot, so saving your work should be on tomorrow’s agenda in order to get this new install right.

Microsoft hasn’t released a public statement to announce this new rollout, but Windows 7, Windows 8.1, Window RT 8.1, Windows 8 and Windows RT are all among the operating systems that will get patched tomorrow. Keep in mind that all these updates will be offered as optional, so you won’t be forced to install them when they become available. You’re still recommended to do it, though.
