Microsoft: Windows 11 2022 Update Can Cause Performance Issues When Copying Large Files

Microsoft says the Windows 11 2022 Update can cause performance degradation when copying large files from remote PCs.


has been spending the last week confirming issues with its new 2022 Update. Introduced late last month, the first major annual update for Windows 11 has arrived with a fair share of bugs. The latest sees Microsoft warn users about the performance degradation when copying large files.

In a Tech Community post, Ned Pyle, Principal Program Manager for Windows Server confirms the issues. Pyle says that the bug happens when copying large files from a remote computer to a system using Windows 11 2022 Update.

He points out that users could see performance drops of up to 40% less throughput. It is worth noting this is for large files weighing multiple gigabytes or more. The simplest way to avoid this issue is to not update to the latest version of Windows 11.

Of course, for those who have already installed 22H2, reverting back or waiting for a fix are the only options. Microsoft says it is investigating the issue and working on a fix.

Update Issues

As is normal with any major update, especially one that will roll to hundreds of millions of machines, there are plenty of early bugs with the Windows 11 2022 Update.

In a recent update post on the Windows 11 Health Dashboard, Microsoft confirmed the Windows 11 2022 Update can have issues finding full features from printers on PCs with certain drivers. In response, Microsoft put a compatibility hold preventing affected systems from installing the update.

Another hold was put on some Intel PCs. Microsoft says some versions of the Intel SST Audio controller driver are causing BSODs on Windows 11 2022 Update.

Tip of the day: downloads can often be frustrating because they are several gigabytes in size and can slow down your internet connection. That means your device may work with reduced performance while the update is downloading. In our guide we show you how to limit bandwidth for Windows Update downloads, so they won't bother you again.
