What is semav6msr64.sys & Mellanox Drivers?

Thanks - as I further check, I first disabled semav6msr64.sys using Autoruns then rebooted. I didn't have the first registry key but deleted the second and deleted the driver file. I now have no trace of semav6msr64.sys.

 

What is semav6msr64.sys & Mellanox Drivers?


I noticed semav6msr64.sys on my system earlier today (also via Autoruns), and eventually tracked down the program which installed it - you heard it here first! It's an Intel file, and just coincidence that SEMA Software authored a driver file with the same name.

On my system the driver was installed by the Intel Driver Update Utility Installer, which I'd installed to update my Intel drivers. Uninstalling this program after use doesn't uninstall semav6msr64.sys, presumably due either to a bug in the uninstaller or to laziness of the development team who wrote it. I don't like leaving software package remnants on my system for no good reason, so removed it as follows:

1. Create a System Restore Point in case the following steps cause any problems.
2. Uninstall Intel Driver Update Utility Installer, if it appears in the installed programs list in Control Panel.
3. Rename semav6msr64.sys to semav6msr64.sys.bk [to be deleted sometime later if no problems are encountered].
4. If, and only if, you're comfortable editing the registry, delete the following keys (otherwise just leave them, they'll have negligible effect):

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_SEMAV6MSR64
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\semav6msr64

 

Intel Driver Update Utility Installer

Hello,

To address your concern, it's safe to run the Intel Driver Update Utility Installer if it's compatible with Windows 10. If not, you can run it in
Compatibility Mode. Regarding with the error "USB controller has failed or not working", refer to the steps provided below:

• Go to Device Manager.
• Uninstall the Universal Serial Bus controllers.
• Right click on any device in the Device Manager, and click Scan for hardware changes. It will automatically reinstall the Universal Serial Bus controllers.

Update us with the result.

Thank you.
