Tell me the steps

1. To uninstall, you should provide the Uninstall=True command line option from the elevated command prompt open to a neutral (not containing Qualys files) directory like this:
   
   "uninstall.exe" Uninstall=True
   
   The quotes " " around the file path are required because the environment variable expands to contain spaces.
2. To uninstall and remove agent registry entries, append the Force=True command line option as specified below:
   
   "uninstall.exe" Uninstall=True Force=True
   
   Important notes about Force=True
   
   The setting Force=True is optional. This removes the registry keys and agent UUID from the host. If an agent is later re-installed on that host a new agent UUID is created (the old one is not used). If you intend to reinstall the agent and wish to reconnect it to its current asset record currently visible in your account, just run the command without Force=True or remove via the Add/Remove programs feature in Windows.
