Does anyone have a PCI Express M.2 SSD here and installed Windows 7 on it? Windows 7 when originally released only had support of the TRIM command on SATA SSDs. When NVM Express arrived, Windows 8.1 added support for it. But Microsoft released KB2990941 for Windows 7. This adds NVMe support to Windows 7. But I haven't got a PCIe SSD to test and verify if TRIM command is also enabled for NVMe storage devices on Windows 7. I only have an M.2 SATA SSD.
If anyone has a PCIe SSD, can you please install Windows 7 with KB2990941 integrated and let me know if TRIM works?
Updated edit: Just got to know from a Twitter follower that it does! Meaning Windows 7 gets full NVMe support with KB2990941 including TRIM command.
