Why does Windows hiding file extensions cause problems when setting up a Kaspa CLI wallet?

If Windows is set to hide file extensions, a batch file you rename to create-wallet.bat may silently end up saved as create-wallet.bat.txt — and a .txt file cannot be executed as a script. Windows hides extensions by default as a cosmetic choice, but it creates a trap for anyone creating Kaspa batch files: the file looks correctly named on screen while the hidden .txt suffix makes it unrunnable. Turning off "hide file extensions" in Windows Explorer settings before you start is a small one-time fix that prevents a confusing failure later when nothing seems to launch.
