Blimey!...... RF is full of IT nerds!
I don't know nuthin' about these bloody things, even now.
For internet use I have this Windows 7 notebook and it has absolutely nothing in it at all. No personal data. No programs.... nuthin....
Every few months it goes wonky, so I connect up the CD drive, insert the recovery disc, completely restore and wipe the entire system and reconnect my dongle. Back online in about thirty minutes.
Oh, and after system recovery I always uninstall every friggin' program possible because I only need to visit forums. Sure, every few months some bug attacks it, so..... recovery disc!!!!
