Microsoft has released cumulative updates KB5022303 and KB5022287 for Windows 11 versions 22H2 and 21H2. The packages in question not only eliminate security vulnerabilities discovered in the previous months, but also increase performance.First of all, let’s mention that they are in the category of mandatory updates. Windows 11 users can check it from the Start > Settings > Windows Update menu. Once installed, the operating systems will change to Windows 11 version 22H2 22621.1105 and 21H2 22000.1455.
Which bugs are fixed?
In both versions, the developers fixed a Local Session Manager (LSM) bug that allowed users without administrator rights to perform functions available only to administrators. At the same time, the ODBC database connection problem has been fixed.
The Windows 11 21H2 update also fixes the blue screen (0xc000021a) error seen on some systems. Microsoft said it has yet to fix two known bugs in Windows 11 22H2. The first is that large files take too long to copy, and the second is that the checksum packages (.ppkg) do not work properly. These bugs will be addressed in future updates.
