Windows 10 KB5006738 (21H1) update now available for download.

It’s that time of the month when Microsoft releases new optional cumulative updates for Windows 10.

However, because the patches are all the same, they all have identical pieces. If you’re on one of those versions or an Insider on Windows 10 version 21H2, you’ll get KB5006738.

Address an issue that prevents you from accessing the pre-provisioning page during the out-of-box experience (OOBE).

A new feature called ‘Content Security Policy’ is now available.

This update repairs an issue with Assigned Access kiosks set up using Microsoft Edge as a kiosk application.

When users log in using Windows Hello for Business after the VPN connection has been lost, a Primary Refresh Token (PRT) update problem occurs.

This patch fixes a Kerberos.dll problem that might result in it not operating correctly within the Local Security Authority Subsystem Service (LSASS).

The Local Security Authority Subsystem Service (LSASS) is a Windows component that, among other things, protects the system from malicious activity by enabling or restricting access to LSASS-protected processes. This happens when multiple application clients are requesting simultaneous User for User (U2U) service for the same user.

Many users complained that the network status text on the credentials screen was incorrect. This fix corrects an issue with Server Message Block (SMB) Query Directory Requests, which results in them failing when the buffer size is too big.

Memory leaks in domain controllers in the forest root domain when you have numerous forests and domains in each.

When you have many forests and domains in each, the SID-Name mapping leaks memory when a request comes from another domain in the forest and goes across forest boundaries. When an address is found for a virtual machine (VM), it uses the value of the fault domain rather than its real one.

There are a few known problems with this update. The Edge Legacy browser will be removed if you have a custom offline installer, but it may not be replaced by the new Edge. There was also an issue in June 2018 when there were difficulties installing future updates after that.

As usual, these are optional updates. This means that you will be able to discover them in Windows Update if you don’t already have them, but you will not be compelled to install them unless you do not have them already.

The next big feature update, the Windows 10 November 2021 Update, is expected to be released soon.
