What's VBS again? Is that Intel's equivalent to AMD's SVM (hardware virtualization)?
No, VBS (virtualization-based security) is a Windows security environment.

Virtualization-based security, or VBS, uses hardware virtualization and the Windows hypervisor to create an isolated virtual environment that becomes the root of trust of the OS that assumes the kernel can be compromised. Windows uses this isolated environment to host a number of security solutions, providing them with greatly increased protection from vulnerabilities in the operating system, and preventing the use of malicious exploits which attempt to defeat protections. VBS enforces restrictions to protect vital system and operating system resources, or to protect security assets such as authenticated user credentials.

    UPDATE - 11 April 2026: due to lid hinges starting to break up this laptop has been retired from active duty. The OS with all software and files has been migrated to my System Seven in 'Other systems' to carry on as my general purpose 'main machine'.

    I've now clean installed 25H2 and used Garlin's scripts to update Secure Boot to CA 2023 and revoke the PCA 2011 certificates. It's new role is to test secure boot issues.

    Info for 2021-2026:
    fully 'Windows 11 ready' laptop. Windows 10 C: partition migrated from my old unsupported 'main machine' then upgraded to 11. A test migration ran Insider builds for 2 months. When 11 was released on 5th October 2021 it was re-imaged back to 10 and was offered the upgrade in Windows Update on 20th October. Windows Update offered the 22H2 Feature Update on 20th September 2022. It got the 23H2 Feature Update on 4th November 2023 through Windows Update, 24H2 on 3rd October 2024 through Windows Update by setting the Target Release Version for 24H2, and 25H2 on 30th September 2025 through Windows Update by setting the Target Release Version for 25H2.

  • My SYSTEM THREE is a Dell Latitude 5410, i7-10610U, 32GB RAM, 512GB NVMe ssd, supported device running Windows 11 Pro.

    My SYSTEM FOUR was a 2-in-1 convertible Lenovo Yoga 11e (1st gen) type 20DA, Celeron N2930, 8GB RAM, 256GB ssd. Unsupported device. This has now been sold. It has been replaced by my System Eight.

    My SYSTEM FIVE is a Dell Latitude 3190 2-in-1, Pentium Silver N5030, 8GB RAM, 1TB NVMe ssd, supported device running Windows 11 Pro, plus Insider Beta, Dev, and Canary builds (and a few others) as a native boot .vhdx.

    My SYSTEM SIX is a Dell Latitude 5550, Core Ultra 7 165H, 64GB RAM, 1TB NVMe SSD, supported device, Windows 11 Pro, Hyper-V host machine. Updated to 25H2 on 30th September 2025.

    My SYSTEM SEVEN is a Lenovo Thinkpad T580, 1920x1080 touchscreen, Intel Core i7-8650U, 16GB RAM, 512GB NVMe SSD + 2nd 512GB NVMe SSD, a supported device for Windows 11. This is my current general purpose 'main machine'. The installed Windows 11 Home from my System One has been migrated to this machine. As its new home has an existing digital licence for Pro I've been able to upgrade the migrated OS from Home to Pro.

Secure Boot itself has zero performance impact on Windows.

Enabling Secure Boot allows you to enable VBS and other kernel security features, which will cause some level of performance drag. It's not from Secure Boot doing its job, but having the option for those enhanced security features that can't happen without Secure Boot building a "safe foundation" by being there at boot time.
True, but we were talking about Bitlocker. 🤣

I also hate UAC, so I always set it to the lowest level so it bothers me only for important actions that might damage my system. Not for everything. This is very important for me because I use a lot of old applications and I have set them to run as Admin for compatibility reasons. I would hate to see the UAC every time I launch one.

I set UAC off. It is pointless. - it doesn't protect anything. You will always be spamming the OK key until it hurts. Then nobody will be to blame but you.

True, but we were talking about Bitlocker. 🤣
BitLocker has relatively low overhead on a modern CPU. Data encryption is done at the per-block level, not encrypted across the entire disk (which would be massively expensive).

Now if you have full BitLocker (Pro) and not Device Encryption (Home) and select a tougher encryption method, then yeah it'll start to be a drag.

I just leave it at the lowest level, AES 128-bit encryption. Heck, even that level has never been broken.
