IMPORTANT: To prevent fingerprint logon issues, be sure
that when you register your fingerprint, that all sides of
your finger are registered by the fingerprint reader.
IMPORTANT: To verify that your computer has a
fingerprint reader, type Sign-in options in the task
bar search box and follow the on-screen instructions. If
Fingerprint Reader is listed as an option, then your
computer includes a fingerprint reader.
