My laptop was becoming unstable, cleaned and pruned and finally gave in to turning updates on. They were turned of because last time microsoft checked my software they turned the computer off, although it was eventually sorted and unlocked I was not prepared to go through the same problems again. So I turned on update and downloaded and installed 32 updates including internet explorer 8. That was when the fun started black bars across the top hiding a lot of function keys, presumably because I failed to verify again. Any answers out there how do I get full function back.
