Disable Core Isolation / VBS

What it does
Turns off virtualization-based security / memory integrity, which can cost a few percent CPU.
The honest verdict
Real performance gain, real security cost — it removes a kernel exploit mitigation. Compy shows it as a trade-off you decide, never auto-applied.
How Compy treats it
It's on Compy's refuse list. Compy will never apply this tweak — and if a guide already talked you into it, reversibility is the whole point of the app.
The Compy Blackbook holds 174 graded entries like this one, judged against your hardware — and every change it does make is reversible, with the receipt to prove it.
