Give Your PC Insomnia. Stop It Going To Sleep.

Windows comes with some default power settings, which force the computer to enter sleep mode if you don't press a key or move the mouse for a few minutes.  Generally speaking, these settings work well.  But sometimes you might need to temporarily prevent the computer from sleeping.  For example, if you're downloading a large file or keeping an eye on a particular web page that keeps refreshing itself automatically.

Useful List of Default Router Passwords For Setup Tasks

If you're helping a friend, relative or colleague to troubleshoot a problem with their broadband connection, the quickest option is often to perform a factory reset on the device and then set it up again from scratch.  The only problem, of course, is that you then need to know the default username and password to which the device will have been reset, in order to log back in and configure it correctly.
