Windows 10 Optional update is now available to everyone

Microsoft has added an optional, non-security update for the currently fully supported Windows 10 versions. This is the October Patch Day preview. Included are not only bug fixes but also new options. That Update KB5017380 is now available for all Windows 10 users.

A few days ago, builds 19045.2075, 19044.2075, and 19043.2075 was released as part of the Release Preview channel, and now they can also be installed by all other Windows 10 users. If you want, you can now install the update manually and benefit from the changes. This is an update with a long list of bug fixes and improvements – plus some new highlights. We had already presented this in a separate article.

Most importantly, a long-announced change: Microsoft improves security by now disabling Transport Layer Security (TLS) 1.0 and 1.1 by default in Microsoft browsers and applications. The group had already made TLS 1.3 encryption in Windows 10 the standard in 2020.

Incidentally, this not only offers security advantages but also performance advantages. But there are other new features in this update. More on that in the release notes at the end of this post. We have translated the highlights for you.

Install manually

The update KB5017380 is a so-called preview update or optional update. Microsoft used to group these updates under the term “C-Updates”. If nothing comes up, the changes contained therein will be automatically distributed to all users on patch day in August.

However, Microsoft does not start distributing the optional updates at once, as it does with the security-related updates. Optional updates are offered via the Windows Update function. You have to search for and start it yourself via the “Optional Updates” menu item so that it is loaded and installed.
