This is where the "KernelOS" name earns its credibility. The customizer modifies:

The installation was blindingly fast. No "Getting devices ready," no Cortana talking about her feelings. Just a progress bar that filled in three seconds. The screen went black.

: The system typically runs with as few as 14 to 46 background processes , compared to 100+ on a stock Windows installation.

The text appeared on the screen, character by character, accompanied by that low, tooth-aching hum.

: This version removes non-essential Windows features like Cortana, Microsoft Edge (sometimes), and pre-installed "bloatware" apps.
