What happened
Microsoft will expand Windows 11's Memory Integrity (HVCI) feature to more PCs starting October 2026. The feature improves security but has been documented to reduce gaming performance on some systems.
Why it matters
If you develop or test on Windows 11 machines, expect HVCI to be enabled by default on more devices from October, which may affect benchmark numbers or game performance on your dev rigs. Plan to test with it on and off rather than assuming consistent performance.
Discussion angle
Whether default-on HVCI will skew local dev-machine benchmarks and whether teams should standardize on disabling it for performance-sensitive work.
