reg-delete:tldr:41e85

This command is used to delete a registry key in Windows using the "reg" command-line tool. Here's the breakdown of the command:

• "reg delete": This is the command to delete a registry key.
• "${key_name}": It represents the variable "key_name" which should be replaced with the actual name of the registry key you want to delete. The dollar sign and curly braces are used to denote variables in certain scripting or command-line environments.
• "/f": This switch stands for "force" and is used to suppress any confirmation prompts. It ensures that the deletion is performed without any user intervention.
• "/va": This switch stands for "value all" and is used to delete all values associated with the specified registry key. If you don't include this switch, only the key itself will be deleted, and any subkeys or values will remain.

To use this command, replace "${key_name}" with the actual name of the registry key you want to delete and run it in a command prompt or script with the necessary permissions to modify the registry. Be cautious when deleting registry keys as it can have a significant impact on your system if done incorrectly.
