This has been getting a fair bit of coverage over the last several days. Microsoft added a native driver for NVMe SSDs to Windows Server, which can allegedly be enabled in Win11 Home & Pro. NVMe SSDs mount to a M2 slot on the motherboard, and are much faster than 2.5 inch SSDs. Up until now Windows pretty much treated these 2 kinds of SSDs the same -- you can experience issues booting from an NVMe drive, but that's another story. In theory, treating NVMe drives as NVMe drives rather than just another SSD gets you faster drive performance -- so far the results reported by Win11 Home & Pro users have been mixed. Reality check: most folks won't notice a meaningful difference between a regular SSD & an NVMe drive. Most will not max out the data transfer rates of an average NVMe drive, let alone faster, or even faster pci 5 NVMe drives.
That said, if anyone wants to try this: I've read that one should check first to make sure Windows\ System32\ Drivers\ stornvme.sys exists -- if not search Windows\ System32\ Driverstore\ Filerepository\. Then add 3 registry entries & restart:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Policies\Microsoft\FeatureManagement\Overrides /v 1853569164 /t REG_DWORD /d 1 /f
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Policies\Microsoft\FeatureManagement\Overrides /v 156965516 /t REG_DWORD /d 1 /f
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Policies\Microsoft\FeatureManagement\Overrides /v 735209102 /t REG_DWORD /d 1 /f
