Windows 10: Driver Aslo.sys problem

Just updated Win 11 to Win 11 24H2 and I keep getting an error message concerning driver Aslo.sys is being blocked. What can I do?

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

 

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.

 

DRIVER IRQL PROBLEM - since Windows 10 upgrade

Hi, Rob

Thank you for posting your query in Microsoft Community. I understand your concern, we in Community will try to help you in the best possible way we can.

The error that you are facing “DRIVER IRQL NOT LESS OR EQUAL (netwsw00.sys)”
is caused by the reasons below:

• Incorrectly configured, old, or corrupted Microsoft Windows device drivers. (very common)
• Corruption in Windows registry from a recent Netwsw00.sys-related software change (install or uninstall).
• Virus or malware infection that has corrupted the Netwsw00.sys file or related Microsoft Windows program files.
• Hardware conflict after installing new Microsoft Corporation hardware, or hardware related to Netwsw00.sys.
• Damaged or removed system files after you’ve installed software or drivers related to Microsoft Windows.
• Netwsw00.sys blue screen caused by a damaged hard disk.
• Netwsw00.sys STOP error due to memory (RAM) corruption.

I suggest that you perform the methods mentioned below and check if you can resolve the issue:

Method 1:

It's highly likely that your Netwsw00.sys blue screen errors are related to corrupt or outdated device drivers. I would suggest that you open Device Manager and check if there is a yellow exclamation mark besides any drivers. If so I suggest that you
un-install and re-install the driver and download the latest update of the driver for Windows 10.

Method 2:

Perform a full system scan to check for any virus or malware infection. If there is any I suggest that you remove the infected file or folder.

Method 3: System Restore

• Click the Start button, then click on Settings
• Then click on Update and Security, locate and select
  Recovery and click on Advance Startup.
• You will now enter the Windows Recovery Environment, once there click on
  Troubleshoot and then Advance Options.
• Click on "System Restore". Enter any administrator passwords (if prompted).
• Follow the steps in the Wizard to choose a restore point.

• Restore your computer

Method 4: System File Checker is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files.

To perform SFC Scan, refer to the below link:

Use the System File Checker tool to repair missing or corrupted system files - Microsoft Support

Note: Steps mentioned for Windows 8/8.1, will work fine with Windows 10.
