The software will run invisibly and the monitored users will NOT know the spy software is running. It will hide its Add/Remove Program entry, installation folder, Windows Task Manager entry, Desktop shortcut, Start menu shortcut, etc.
If you run the spy software in the Stealth Mode, you can not locate it in Start menu or Program Files directory as usual. You can only use a hotkey to bring it back. The hotkey is Ctrl+Alt+X as default. Note: hotkey is only available in the Windows user account where the software was installed. It is disabled in other user accounts so that other users will not be able to unhide the software by accidentally pressing the hotkey.
It is not necessary but recommended to setup a login password for the software. It makes the software more secure and unaccessible to the monitored users. Tip: For best results, make your password alpha-numeric, so others wont be able to guess it easily!
