After updating to the new Windows 11 25H2 version, disk performance has decreased.
After installing these two updates, SSD sequential write speed dropped from 6000 MB/s to 4000 MB/s, and 4K random read/write speeds also decreased significantly. Is this a widespread issue? How can it be mitigated or rolled back?

You noticed your SSD's speed drop significantly after installing updates. This might be caused by driver conflicts, firmware issues, or Windows storage management changes introduced by those updates.
