- Windows 11 23H2
Hello. I'm on build 22631. Win11 just updated to 23H2. In the process, a key app for me ceased working, due to VBS being enabled. It worked under Win11 22H2, with the Memory Integrity setting disabled. (Long story short: I undervolt and achieve a 77% overclock on my i7-8750h, cannot upgrade to a newer laptop due to reasons. ThrottleStop ceased working, Intel XTU doesn't work either and blames VBS. I do a very CPU-demanding work for a living and this is the only PC I'll have access to in the short to medium term.)
I've tried the following:

I'm out of ideas. Any help would be greatly appreciated. I use this PC for working on CPU-heavy apps, and truly halving the performance of an already old processor is killing me.
I've tried the following:
- Core Isolation / Memory Integrity is off. (It "stayed" off between 22H2 and 23H2)
- Disabled Credential Guard
Following this guide Configure Credential Guard - Windows Security, I disabled Credential Guard both with the Group Policy Editor and with the registry,
I also disabled Credential Guard with UEFI lock, which asked me to press F3 before loading Windows twice, once for Credential Guard and then for VBS
- Disabled VBS with the bcdedit commands as instructed here (the Group Policy option is the same as in the Credential Guard subsection!)
Configure Credential Guard
Learn how to configure Credential Guard using MDM, Group Policy, or the registry.learn.microsoft.com
- I've turned off Virtual Machine Platform (VMP) using these instructions Options to optimize gaming performance in Windows 11 - Microsoft Support
- I see no relevant BIOS options (other than outright disabling all virtualization)

I'm out of ideas. Any help would be greatly appreciated. I use this PC for working on CPU-heavy apps, and truly halving the performance of an already old processor is killing me.
