Kaspersky preventing Microsoft Direct storage from working


Recommended Posts

I was checking to see if my 2 NVMe drives I have are DirectStorage compatible. But the system says they arent. Here are my drives: ADATA XPG SX8200 1TB O/S),. 2TB Samsung 970 Evo plus (Games only), 4TB WD Black. (User data and programs mainly). I get this incompatible reasons for both NVMe drives:

Status: 494 (The specified driver does not support BypassIO operations)

Driver: klpnpflt.sys

Reason: The driver's StorageSupportedFeatures registry value is not defined

Storage Type: NVMe

Storage Driver: Not BypassIo Compatible

 

The Klpnpflt.sys driver is from Kaspersky and preventing Direct Storage from working.  Will this be fixed with an update from Kaspersky or will I have to get rid of the KIS?

It does not prevent DirectStorage from working, it just prevents BypassIO from being enabled. DirectStorage works without BypassIO, but it is inefficient because it does not support an optimized I/O path.
