Hi there

I don't why but I can't turn on Kaspersky hardware virtualization although I followed all the steps and did everything (I also enabled it in bios). I even turned off Windows Hyper-V and core isolation options (As they're visible in the attached images) and reinstalled Kaspersky but they didn't work neither. I assume that there's conflict or incompatible with new Windows 11 24h2 build. There wasn't any problem with 23h2 but again any solution for this?

Hi

No

This problem has been around for many years... Here is decision:

1) Disable Self-Defense in Kaspersky settings.

2) Right-click the application icon in taskbar and click "Exit".

3) Find this registry key starting with "klhk" and change the "FailSafeMode" value there to 1 (see my screenshot).

4) Restart your PC and don't forget to turn on Self-Defense later!

 

 

Hello

Thank you

But doesn't work?

Hello @karkas20

It sounds like you've done a thorough job of troubleshooting the issue with Kaspersky hardware virtualization. Since you suspect there may be a conflict with the new Windows 11 24H2 build, it's possible that either the new build is introducing compatibility issues, or another feature is interfering with virtualization.

Here are some additional steps to try in case any were missed:

1. Check Windows Security Core Isolation (Memory Integrity) Again

Sometimes, even after disabling the memory integrity feature, the change doesn't fully apply. Make sure:

• Memory Integrity is still off in Device Security > Core Isolation Details.
• Restart your system again after disabling to ensure changes are applied.

2. BIOS Settings

Since you have enabled virtualization in BIOS, make sure the following are configured properly:

• Intel VT-x/AMD-V is enabled.
• Intel VT-d (if present) is enabled.
• Secure Boot is disabled temporarily, as sometimes it causes conflicts with hypervisor-based software.

3. Disable Hyper-V Completely Using Command Prompt

Even after turning it off from the UI, Hyper-V can still leave residual components that interfere with other virtualization technologies. To disable Hyper-V completely, run the following command in an elevated Command Prompt:

Copy code

bcdedit /set hypervisorlaunchtype off

After running the command, reboot your computer and try enabling hardware virtualization in Kaspersky again.

4. Disable Windows Sandbox or Windows Subsystem for Linux (WSL)

If you have Windows Sandbox or WSL enabled, they might conflict with hardware virtualization. To check and disable them:

• Go to Control Panel > Programs > Turn Windows features on or off.
• Location Information:https://support.kaspersky.com/help/Kaspersky/Win21.19/en-US/283105.htm
• Uncheck Windows Sandbox, Virtual Machine Platform, and Windows Subsystem for Linux.
• Reboot your system.

5. Try Kaspersky's Technical Support With A Ticket

If all of the above steps don’t resolve the issue, it may indeed be related to an incompatibility with the new Windows version. Contacting Kaspersky technical support could help, especially if they have a patch or workaround for the issue.

By ensuring all possible conflicting services are disabled and confirming with Kaspersky about 24H2 compatibility, you should be able to get hardware virtualization working again. Let me know how it goes!

Thank you

@karkas20

Thank you for the provided information, we are on it. Will keep you posted of the progress.

@KarDip

Kaspersky for Windows is compatible with 24H2. The issue with virtualization is treated as a high priority bug, not a compatibility issue. 

Regardless of the virtualization problem, also please note, that Location Services need to be enabled for Smart Home Monitor to function correctly. More information:

Hello @karkas20

Okay try this also.

If enabling Location Services didn't solve the issue with Kaspersky's Smart Home Monitor or hardware virtualization, let’s try some additional steps to narrow down the problem. 

---

1. Ensure No Hypervisor is Running

Even if Hyper-V appears off, virtualization features might still be blocked. Let’s ensure no hypervisor or virtual components are running.

• Open Command Prompt (as Administrator) and run:
  Copy code

  systeminfo | findstr /i "hyper-v"

   
  If the result shows Hyper-V requirements are enabled, it indicates a hypervisor is still active. If so, run:
  Copy code

  dism /online /disable-feature /featurename:Microsoft-Hyper-V-All /norestart
  Reboot your system.

---

2. Disable Virtualization Conflicts via Group Policy

1. Open the Local Group Policy Editor by typing gpedit.msc in the Start menu.
2. Navigate to:
   Copy code

   Computer Configuration > Administrative Templates > System > Device Guard
3. Disable:
   • Turn On Virtualization Based Security
4. Reboot your system and try again.

---

3. Check for Hidden Virtualization Software (VMWare/VirtualBox)

• If you’ve ever installed VMWare, VirtualBox, or other virtual machine software, ensure they are uninstalled or disabled as they can conflict with Kaspersky's virtualization.

---

4. Reinstall Kaspersky with Clean Install

1. Uninstall Kaspersky using Kaspersky Removal Tool to ensure no leftover files or settings remain:
   • Kaspersky Removal Tool Download
2. After rebooting, download the latest version of Kaspersky and install it again.
3. Check for any pending updates in Kaspersky after installation

Let me know if anything improves!

Hello @shadowtabby144

We know  that Kaspersky has encountered issues with hardware virtualization on Windows 11, especially with the recent 24H2 update. As you know  seems to be affecting many users, and the root of the issue likely lies in compatibility between Kaspersky’s virtualization drivers and the Windows 11 hypervisor changes or security features in the latest build.

Did you try this?

Current Workarounds for the Kaspersky Virtualization Bug on Windows 11

1. Ensure Complete Hyper-V and Virtualization-Based Security (VBS) Shutdown

   • Disable Hyper-V using:
     Copy code

     bcdedit /set hypervisorlaunchtype off
   • Disable Virtualization-Based Security (VBS) through Group Policy:
     • Open Group Policy Editor (gpedit.msc).
     • Go to Computer Configuration > Administrative Templates > System > Device Guard.
     • Set Turn On Virtualization Based Security to Disabled.

2. Reinstall Kaspersky in Compatibility Mode

   • Uninstall Kaspersky completely using the Kaspersky Removal Tool.
   • Reinstall the latest version but use Compatibility Mode (try Windows 10 compatibility) to mitigate any OS-specific issues.

3. Check for Kaspersky and Windows Updates

   • Kaspersky may release updates to address this compatibility issue with 24H2, as they frequently patch critical compatibility bugs. Force an update check in Kaspersky.
   • Ensure Windows Update is set to automatic in case Microsoft releases a hotfix for this issue.

Thank you

I also confirm that hardware virtualization still does not work

Heyo. 

 

Still no different for me either.

 

I’m also experiencing the same virtualization problem after updating to Windows 24H2. I’ve tried every method I could find online and on Kaspersky’s support pages related to virtualization, but nothing has worked so far.

Currently, I have a ticket open with Kaspersky support, but there’s still no fix. I’ll make sure to update here if anything changes.

It might be an issue on Kaspersky’s side or something related to the Windows 24H2 update itself. Let’s hope we get a resolution soon.

Fix for Kaspersky Virtualization Issue (Device Guard and Credential Guard)

I was having issues enabling virtualization in Kaspersky, and I couldn’t get it to work with Kaspersky’s support team, as they weren’t able to provide a solution. I tried everything on Kaspersky's virtualization page and every suggestion I could find on the internet, including everything Kaspersky support advised, but nothing worked.

I found a solution after reading a thread on Reddit, and after doing some more research, I applied the fix. Here’s what I did:

1. I downloaded and ran the Device Guard and Credential Guard Hardware Readiness Tool from Microsoft:
   Download Link

2. I ran the script from the tool with elevated permissions in PowerShell (I had to allow PowerShell to run as an administrator).

3. The script prompted me to disable Device Guard and Credential Guard. After disabling them, I was asked to reboot my PC.

4. After rebooting, I confirmed that Credential Guard was disabled, and Kaspersky no longer showed errors related to virtualization.

5. Virtualization in Kaspersky is now working fine, and everything seems to be running smoothly!

I think this fix worked for me, but since I don’t know much about advanced computer settings, I’m not 100% sure if it could cause any hidden issues. I just followed the tool’s instructions and rebooted. The system seems stable, and Kaspersky is working as expected now.

If something I did is wrong or could cause issues later, please let me know.

Hi @shandonfx ,

 

thanks for your workaround but I did not make the changes because someone said that they were lost upon reboot and also because I would expect an automatic and working solution for everyone distributed by Kaspersky.
At the moment I will remain without hardware virtualization enabled hoping that they solve the problem.
If any Kaspersky employee reads us, can you please tell us when it will be definitively solved?

Thanks anyway for your help.
