Will Windows XP (or any other OS) recognize Hardware KeyLogger as a new hardware that was installed?
No. The Hardware KeyLogger installs totally transparently. The operating systems will not know it’s there. Hardware KeyLogger does not use any resources from the OS and there is no software driver needed. The installation is the simplest form of plug-n-play. You plugs it in, and it’s working. No operating system or software will ever know it’s there.
