Users are already reporting serious compatibility issues; the system may stop booting and you will be faced with the Blue Screen of Death instead.
The issue is likely caused by the new Windows 24H2 settings increasing the amount of memory allocated for I/O caching on SSD drives without onboard DRAM cache.
These devices use the Host Memory Buffer (HMB) feature, which uses the computer’s main RAM.
However, Windows 24H2 reserves up to 200 MB for caching instead of the usual 64 MB, which causes system instability.
While Western Digital and Microsoft are working on a solution, users can downgrade to Windows 11 23H2 to avoid errors or use a workaround via the registry to restrict HMB.
