Have two desk tops one running Win8.1 the other Vista and linked to a wired keyboard and wireless mouse. Had no problems with the installation. Swapping between the two screens there is sometimes a glitch in the graphics settling back to the highest setting, but that is easily remedied, but can be annoying when it happens. There's been no problem with the keyboard or mouse changes. I first tried a wired mouse and that worked fine, then went to a wireless mouse and again have had no problems. I like the button control that swaps between the two PCs, and the leads are long enough to reach both PCs.
