Microsoft had earlier published the update KB5007253 to the Release Preview channel for Windows 10. This update applied to both versions 21H1 and 21H2. The update did not include any new features, but rather only a number of improvements and fixes.
They have now republished the same update. But this time, they included another fix that upgrades the operating system’s build as well.
Installing KB5007253 will now upgrade your build to 19044.1381 if you are on Windows 10 version 21H2, and build 19043.1381 on Windows 10 version 21H1.
You can check your Windows version and build by typing in winver in Run.
Improvements and Fixes
Installing this update will implement all previous updates and fixes in KB5007253 except for the new addition. If you have already installed the update the last time it was released, then only the new fix will be implemented.
Microsoft has fixed an issue that may affect devices using Windows Hello for Business and are on the Azure Active Directory (AAD). The problem is said to be experienced when such devices try to access on-premises resources.
