[software] Microsoft is changing Windows 11 to help you save money on power bills

[Rainstorm.]

 

Windows 11 has received another preview build in the Dev channel, and it brings in a number of tweaks and additions, including beefing up a feature that should help your PC use a bit less electricity.

That would be Content Adaptive Brightness Control (CABC), which as of preview build 23424, works not just with laptops on battery power, but when they’re plugged in – and indeed with desktop PCs too.

What CABC does is intelligently dim (or lighten) certain parts of the screen depending on what content is being displayed, the idea being that it can cut back power usage without hampering the ‘visual experience’.

In other words, the tweaking on the dimming front shouldn’t make any noticeable difference to the image you’re looking at on-screen, and it should save you a bit of power (and therefore cash, over time).

The feature can be set to be always on, or it can be disabled, or alternatively you can choose to have CABC kick in only if you’re on battery power (on a laptop of course).

What else is new for build 23424? There’s a new widget board which is now bigger, so it’s three columns wide (rather than two) and much roomier (assuming the device’s screen has enough real-estate to cope).

Along with this, there’s the usual gamut of fixes and minor tweaks, all of which are detailed in the usual blog post(opens in new tab) published with every preview build.

Notable pieces of minor tinkering include improving the speed of running searches within the Settings panel, and a change to produce better performance when playing games with a high polling mouse (a super-precise fancy gaming mouse, basically).
