Elenarie: Nope. We're not in the XP days anymore where you had to do maintenance yourself.
I barely restart the OS (when it is required, for an update or some application that may require one), let alone reinstall it.
dr.zli: ^^^ this ^^^, my windows 7 machine works 24/7/365 with restarts only for upgrades, this was a windows 7 day 1 purchase and it's working ever since
nice! you realize of course, that not EVERY machine is going to work like yours does! windows does have flaws, hardware stops working, viruses attack. I got mine three years ago, and i've basically had it on without turning it off mostly for the whole 3 years without ANY problems!
all i'm saying is, good luck my freinds without any problems ever, you are a truely exceptional lot.
