If you're looking to change the calibration on Windows 10, there are a few different ways you can go about it. One option is to use the Display Color Calibration tool that's built into Windows. This tool can be found by going to Start > Settings > System > Display. Once you're in the Display settings, scroll down to the bottom and click on the 'Advanced display settings' link. From here, you'll see a new window with a 'Calibrate color' button near the bottom - click this to launch the calibration tool.
Another option is to use a third-party calibration tool such as HCFR or CalMAN. These tools will usually give you more control over the calibration process than the built-in Windows tool, and they may also provide other features such as support for multiple displays or projector screens.
Once you've launched your chosen calibration tool, follow the instructions provided to adjust your display settings until you're happy with the results. Remember to save your changes when prompted, so that they'll be applied every time you boot up your PC.
