1. Don’t install Apple’s Bonjour programme.
Bonjour is meant to simplify network setup and connectivity between your computer and ‘smart’ devices. In fact Windows handles network setup perfectly well, and Bonjour simply adds another layer of complication. In some cases it will stop internet access completely. If you are running Vista and install service pack 2 (still at RC stage), and then find you have no internet access, Bonjour is almost certainly the cause.
Google lists about 1.5 milion pages if you search under Bonjour problems. One of those problems is that it installs itself on your system without your permission. That’s just rude.
Check to see whether it is installed on your computer. If it is, uninstall it.
2. Don’t install Magentic wallpapers or screensavers.
You may be offered these, or already have them, if you use (why?) Incredimail. They look pretty, but can cause a number of problems, including making Internet Explorer pop up a difficult to get rid of blank page whenever the screensaver kicks in.
3. If you use Office 2007 and have lost or cannot see the ribbon, right click on the menu bar and uncheck ‘Minimize the Ribbon.’
