win 10 night light not working or greyed out

When the nightlight function cannot be used or is displayed in gray, you should first check and update the graphics card driver. 1. Update the graphics card driver to the latest DCH version, and priority will be downloaded from Intel, AMD, NVIDIA or the official website of the brand computer; 2. Confirm that the driver supports WDDM2.0 or higher, you can view the "Driver Model" through the dxdiag tool; 3. Close the "Color Filter", enter "Settings → Easy Use → Color Filter" and turn off the function; 4. Check whether "Enable Night Mode" under "Computer Configuration → Administrative Templates → Windows Components → Display" in Group Policy (gpedit.msc) is disabled. If there is a registry key DisableNightLight and the value is 1, it needs to be changed to 0 or deleted.

Why are my local files (file:///) not opening in Google Chrome?

Chrome restricts local file access for security reasons. Solutions include: 1. Use a local development server (such as LiveServer or Python's http.server) instead of file:///; 2. Ensure the file path is correct, use forward slashes and avoid special characters; 3. Check whether there are experimental settings for security or file access in Chrome://flags and reset it; 4. Troubleshoot enterprise policy restrictions; 5. You can temporarily use Firefox to test whether the file is normal. The best practice is to always use local servers for development, as modern web features mostly require server environments, which avoid compatibility issues and improve security.
