>you need administrator to install a different keylogger

nope. you need administrator if you want to install for all users, but there's nothing preventing a user from keylogging himself.

You need write access to:

HKLM\Software\Synaptics\%ProductName%\Default

Which requires administrator or equivalent, so that is preventing a user from even keylogging themselves.

i meant you can install any other keylogger without admin.
