Use Windows Remote Access

This video from the "Ask the Techies" series on Veoh.com explains how to connect to a remote computer using built-in services in Windows -- a bonus because you can skip the third-party options. It's like talking to a couple of IT guys in a back room somewhere. Like all good how-to videos, there are cutaways to the actual configuration screens in Windows -- interspersed as the guys are talking and without getting overly technical and dull.

Use an Old PC as a Server

Instead of tossing out an old PC, you can turn it into a server -- and this video from VitaminCM.com explains the steps. It's a little dated -- which is fine, because most of us with old PCs lying around are not running Vista on them anyway. There's also no extra banter or even a talking head explaining the steps -- just the audio and screen actions to guide you through the process quickly.

Recall E-Mail Sent by Mistake

Here's an instructional video from VideoJug.com that is part comic relief, part serious guide. I like how the video pokes fun at the concept while inserting a few gems, such as the ability to delay sending mail for a few seconds so you can rethink that message to the boss or block a mass e-mail that was supposed to use a blind copy. Those tips are usually buried in a manual or help file; here, they are just part of a goofy video.

Speed up Windows

This Tinkernut.com video -- which is a little longer and more advanced than some of the previous how-tos -- goes into great detail about defragging Windows, deleting Internet history and beefing up performance by shutting down unneeded programs on a system that has started to show its age. Like most of the videos on the WonderHowTo.com site, the quality is good and focuses just on the computer screen without the superfluous jokes or talking head -- it means you can learn just the specific steps required.
