Known Microsoft Windows 11 Issue Decreases SSD Speeds Amongst Other Issues

wccftech.com:

Users report that read speeds from SSD have dramatically reduced after the newest Windows 11 update (Windows 11 Version 22H2 - KB5023706). While the few reported events were thought to be localized to the ADATA XPG SX8200 Pro 1 TB SSD, the issue is found to plague other manufacturers and can be fixed after uninstalling the update.

The newest Windows 11 update, which has the codename "Moment 2," is downloading to PCs starting today, with updates to quality of life and the integration of the ChatGPT-based Bing Chat into the search bar on the user's taskbar. However, the drive speed issue is apparent and appears to be a known issue with this newest update.

In one of the "Known Issues" on Microsoft's support site, the following appears:

Copying large multiple gigabyte (GB) files might take longer than expected to finish on Windows 11, version 22H2. You are more likely to experience this issue copying files to Windows 11, version 22H2 from a network share via Server Message Block (SMB) but local file copy might also be affected.Windows devices used by consumers in their home or small offices are not likely to be affected by this issue.

The few reports that have already been located on Reddit show that the SSD read speed dropped by half, if not more, in the few cases listed. One of the users has the ADATA XPG SX8200 Pro 1TB SSD in their Lenovo Legion 5 laptop, while the other has the same SSD model in their 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 Windows 11 Version 22H2 (KB5023706) update and found the problem had disappeared.
