Why you should give yourself a few days before updating your machine to Windows 11 242H

It’s always a good idea to install the most recent software update to take advantage of new features and improve security. One such update with a lot of new features was Windows 11 24H2. However, other customers claim that rather than making their computers better, the update is making them worse, especially if they have a WD Black SN770 or WD Blue SN580 SSD installed.

Users complain of problems like “stornvme and The driver detected a controller error on \Device\RaidPort1 or 2,” which sends PCs to Microsoft’s notorious blue screen of death, according to WD’s own forum. Reverting to the earlier version of Windows 11 is now the only option to avoid this.

The Host Memory Buffer (HMB) feature is allegedly the origin of this problem in the company’s high-end flagship SSD, the WD Black SN770. Because of this feature, SSDs can provide improved drive performance by using the system’s DRAM as a cache. TechSpot claims that WD uses 64 MB of system memory as HMB, whereas the most recent version of Windows 11 24H2 saves up to 200 MB of HMB, which could lead to system crashes.

Reverting to the Windows 11 23H2 upgrade is one temporary solution to this issue, which is causing the computer to display the Blue Screen of Death (BSOD). Another technical solution is to manually limit the HMB memory to 64 MB using the Registry Editor tool. This will allow customers to run the most recent version of Windows 11 24H2 on computers that have the SSDs listed earlier.

Wait a few more days before updating to the most recent build if you’re using a Windows 11 computer. Microsoft is probably going to release an update to fix this fault in the coming days.
