Microsoft has today released a new Windows 10 build 19044.1381 (21H2) / 19043.1381 (21H1) to insiders on the release preview channel. This is a tiny update in the sense that it only contains a single fix, albeit a notable one, and adds to the previous builds released a couple of days ago under the same KB5007253. Hence, the long list of fixes Microsoft brought can be viewed here with Build 19044.1379 (21H2) / Build 19044.1379 (21H1). The update fixed remote printer issues, resolved a 32-bit Excel bug, and more.
Now, moving over to what today's build brings in addition to those earlier fixes, Microsoft says that it fixed a problem plaguing Windows 10 PCs that use Windows Hello for Business service on Azure Active Directory (AD) servers when accessing on-premises resources, such as file shares, among other things, and was likely causing user authentication problems and perhaps other inconveniences.
The changelog reads:
We fixed an issue that might affect devices that use Windows Hello for Business and are joined to Azure Active Directory (AD). These devices might experience issues when they access on-premises resources, such as file shares or websites.
