Known Microsoft Windows 11 issue reduces SSD speeds, among other things

Users report that SSD read speeds have dropped drastically after the latest Windows 11 update (Windows 11 Version 22H2 – KB5023706). While the few reported events were believed to be localized to the ADATA XPG SX8200 Pro 1TB SSD, the issue was found to plague other manufacturers and can be resolved after uninstalling the update.

Windows 11 update slows down SSDs during data transfers; Microsoft is aware of the issue

The latest Windows 11 update, codenamed “Moment 2”, will be downloaded to PCs starting today, with quality of life updates and the integration of ChatGPT-based Bing chat into the search bar on the user’s taskbar. However, the drive speed issue is evident and appears to be a known issue with this latest update.

One of the “Known Issues” on Microsoft’s support site states the following:

Copying large multi-gigabyte (GB) files may take longer than expected on Windows 11 version 22H2. This issue is more likely to occur when copying files on Windows 11, version 22H2 from a network share via Server Message Block (SMB), but local file copies can also be affected. Windows devices used by consumers in the home or small office are not likely to be affected by this issue.


The few reports already found on Reddit show that SSD read speeds have dropped by half, if not more, in the few cases listed. One of the users has the ADATA XPG SX8200 Pro 1TB SSD in his Lenovo Legion 5 laptop while the other has the same SSD model in his HP Omen 16 laptop. The latter user noticed that the boot time, which initially took an estimated fourteen seconds, increased to thirty-one seconds. The former user uninstalled the update for Windows 11 Version 22H2 (KB5023706) and found that the problem was gone.

We tested the issue with the Teamgroup A440 Pro 2TB SSD, a main drive in one of our review units. The transfer rate paused for a few seconds during file transfer and then resumed. It has now been confirmed that the issue is centered on the mentioned ADATA SSD and correlates with Microsoft’s known issues with the latest update.

Microsoft explains: “To mitigate this problem, you can use file copy tools that don’t use a cache manager (buffered I/O).” They also give two “built-in” command line tools to fix the error, mentioning that they are working on a full solution. The two command lines are shown below:

robocopy \\someserver\someshare c:\somefolder somefile.img /J xcopy \\someserver\someshare c:\somefolder /J

Another issue mentioned is installing the latest “Moment 2” update. Reddit Users Show “Download Error” When Downloading Latest Update The code 0x80244007 appears, which has occurred in the past “when Windows tries to check for updates on a WSUS server”. Microsoft support reports that this problem occurs because the operating system cannot renew certain cookies that are required for Windows Update. Microsoft recommends installing “Update Rollup 2883201”.
