In some parts of the world, the day is more extended by about 1 hour during the autumn or summer, and the day is shorter in winters. This affects the clock in the Windows system and can distract people using it. So there is a feature in the Windows system called daylight saving time that appears to be greyed out and many Windows users are unable to use or turn on this feature.
This may be because of the reason that they might have set the wrong time zone which does not need the daylight saving time feature hence it shows greyed out.
You can also enable this feature by forcing the system to do it by changing the registry file on the system. Don’t worry if you are also facing this issue. We have explained the two methods with which you can easily resolve the issue and able to use the daylight saving time feature on your Windows PC.
