''Make sure your computer is up-to-date with the latest drivers. Take the hassle out of finding and keeping track of the drivers for your printer, scanner, mouse and other hardware devices.''

This means to me, a non-techy-scared-old-man, computer users have to :

1... Keep track of drivers for hardware devices, printer, scanner,
(both I do NOT have) mouse and whatelse;

2... It is a hassle to find the drivers;

3... It is also a hassle to keep track of those 'found' drivers.

Please tell me how important it is for me to :

a... Search and Find ''Drivers''
b... Keep Track of those Drivers

c... Is it mandatory of computer users to purchase ParetoLogic or similar program ?
d... What harm in ignoring this advise ?

Please help me have peace of mind from this proverbial sword hanging above me --- thank you.
