Microsoft has quite a few exclusive file formats going for it, and one of them is MSU. Short for Microsoft Update, this is a standalone installer that is used to deploy Windows (and other such software) updates.
And since the upcoming Windows 8.1 Update 1 is as clear an update as any, there is a fair chance that Redmond might release this new version in the aforementioned file format — nice going there, as it will ease up a lot of installation concerns for users looking to upgrade.
This new information comes from famed leaker WZor, who is claiming that this new version of Windows is being delivered in this format. The current build number, by the way, stands at 19942.
A bunch of different screenshots have also been published that show the installation process being handled by the MSU file, similar to how other patches from the software titan are released.
You can take a look at these below:
What this also means is that not only could Microsoft deliver this update via Windows Update, it may also decide to make it available for download separately.
People, as you may recall, encountered some issues when deploying Windows 8.1 via the integrated store, and the company seems poised to prevent any such problems from arising this time around. Excellent, if true, it must be said.
We should know for sure as we get closer to April release date.
