Windows 11 KB5022303 and KB5022287 cumulative updates are now available to the public

Patch Tuesday is here! For unawares, Microsoft rolls out security updates for all its products every second Tuesday of the month. Today, Microsoft kicks off the first Patch Tuesday of 2023. Just like the last month, there are two new builds rolling out for Windows 11, one for the 21H2 build and the other is the 22H2 build. The new cumulative updates are Windows 11 22621.1105 and 22000.1455.

Windows 11 users running on the 22H2 build receive the new update with KB5022303 (2621.1105) version number. Whereas, if your PC is still running on the Windows 11 21H2 then the build number is KB5022287 (22000.1455). The update is rolling in a staged manner and will be available to everyone in a matter of time, in case you are in a hurry, then you can manually download the new builds here.

The new incremental updates weigh small in size, the cumulative update on the 22H2 systems sized around 273MB for x64-based systems and 378MB for ARM64-based. Whereas the KB5022287 build weighs 315MB in size for x64-based systems and 432MB on ARM-64 based systems.

In terms of changes, the new update addresses the blue screen issue on the 21H2 build that might affect the startup on some Windows devices. Apart from that there are two common fixes available on both builds.

  • This update addresses issues that affect the Local Session Manager (LSM). These issues might allow users who do not have admin rights to perform actions that only an admin can.
  • This update addresses a known issue that affects apps that use Microsoft Open Database Connectivity (ODBC) SQL Server Driver (sqlsrv32.dll) to connect to databases. The connection might fail. You might also receive an error in the app, or you might receive an error from the SQL Server.

Obviously, the Patch Tuesday update will also bump up your system’s security to the latest version. This time, Microsoft didn’t mention anything new in the known issues section, here’s the official announcement for the 21H2 and 22H2 build.

The latest Windows 11 update is available for everyone, so if you haven’t opted for Insiders you will receive the cumulative update on your Windows PC. To check for the update head over to Settings > Windows Update. If you don’t see the new build, click on Check for Update.

After downloading the update, you need to restart your device after charging it to at least 50%.
