Fixes and improvements

Since this update is the first update of 2023, and also fixes an actively exploited vulnerability, you should update your system as soon as possible.

The Local Session Manager (LSM) is affected by the issues addressed in this update. These potential security issues might allow unauthorized users who do not have admin privileges to carry out actions or access information that only an administrator should be able to.The purpose of this update is to fix a problem identified in Microsoft Open Database Connectivity (ODBC) SQL Server Driver (sqlsrv32.dll), which causes issues for apps trying to connect to databases. The connection could possibly fail. In addition, you might also encounter an error while using the app, or you might receive an error message from the SQL Server.

With these improvements, there are also some known issues that you should be aware of before upgrading to this build. Windows 11 servicing stack has been updated to version 22621.898.

Known Issues

Provisioning Windows 11

Microsoft has released a statement warning users that the Windows 11 version 22H2 might not work properly and may cause issues. This can cause the Windows 11 operating system to be configured only partially, or can cause the OS to restart when on the Out of Box Experience (OOBE) screens. This is because the Windows 11 operating system cannot correctly process the information it receives from the hardware. Provisioning is done by IT administrators when setting up new devices for businesses or schools using .PPKG files. Currently, the only workaround Microsoft can come up with is to provision the Windows device before upgrading to the 2022 update, while they work on a permanent fix.

Slow File Transfers

Another issue that Microsoft acknowledged is the slow file transfers in Windows 11 22H2. As per an earlier announcement on Microsoft Tech Community, the company confirmed that updating your operating systems to Windows 11 2022 Update slows down file transfers of larger files (files in GBs) by almost 40% of the regular speed. Since file transfer uses the SMB protocol, there ought to be an issue with the protocol itself resulting in slower file transfer speeds for larger files. However, according to Microsoft, the problem isn’t with the protocol. As a workaround, Microsoft recommends using the Robocopy command-line utility to transfer files from one place to another over the network. This will restore the transfer speeds to the older Windows 11 version 21H2 speed. Alternatively, you can also use the xcopy command with a similar syntax to Robocopy. Learn how to use Robocyopy and Xcopy top copy folder structure without files. You can use the command Robocopy with the /J switch to transfer large files without buffering. Here is the syntax to be used in an elevated Command Prompt: Replace someserver and someshare with the complete server name and file name that needs to be copied, respectively. Also, replace somefolder with the name of the folder where you want to replace the copied file, and somefile.exe with the file name and extension you wish to save the file as. This is the only workaround for now until Microsoft works on a permanent fix. After considering both the improvements as well as the known issues in this update, if you still feel like upgrading to this build, continue reading to learn how.

Final Analysis

Patch Tuesday updates are thoroughly vetted by Microsoft and other Insider users through feedback. Moreover, type C and D updates are also released prior to Patch Tuesday updates to address any remaining issues. Even so, the final update is not without its problems. Users on Windows 11 21H2 may experience some issues, but there are more issues with version 22H2. If you have to transfer large files, then updating to this build would definitely be a problem for you. However, if it is an occasional transfer of data, you can use Robocopy or xCopy cmdlet to get the job done quickly.
