How do I install a WLAN driver on Windows 11 from a zip file?

First off, you need to unzip the file you downloaded. Once that's done, take a look at the contents. What files do you see in there? That can give us clues on how to proceed with the installation.

Be careful when dealing with drivers! After unzipping, check for any setup files or instructions in the folder. It's also worth mentioning that major changes could affect your system, so ensure you've backed up any important data before making changes.
