The Deadly Creeping Registry

Available For Immediate DownloadComputers perform best when they receive regular, professional maintenance. The installation and un-installation of fonts, software, hardware, and drivers often leave remnants behind in your registry, resulting in a tangle of unused applications, broken drivers, and incomplete and empty command signals. This mass of confusion slows down your computer and if not addressed promptly can lead to serious problems such as computer freezing, programs not responding, and system crashes.

You made the investment in your PC so that you could enjoy the benefits of a fast, easy machine that would make your life easier and more enjoyable. Unfortunately, after continued use, all PC’s suffer the effects of a corrupt and ineffective Windows Registry, causing error messages to appear, slow loading, and system crashes. Eventually, that machine that was supposed to make your life easier is now the source of your greatest frustration.

Registry Scan & Repair Software (such as RegCure) offers you the ability to safely perform a full scan your your computer's Windows' Registry, and then automatically repair any detected items after a scan. With these tools, you can usually configure the settings so that a repair of detected items occurs after each scan.

Important note:  Be SURE your perform a full Registry Backup before making any repairs or changes to your Windows Registry.  So you should use registry repair tools that perform an automatic backup every time you use it (which RegCure does). That way, you can restore the registry any time should you have the need.

Killer Bots

We all know about viruses, worms, trojans, spam, and other forms of Malware.  However, you may also have heard about something called a "bot".  Bots are basically software - automated programs - that perform tasks on the web.  Some bots are good - like FrontPage bots.  Other bots are bad - bad - bad bot!  The bad bots make our lives absolute misery at times.  If you have a website with a contact form, you probably have experienced bot attacks on your forms, sending unlimited spam through the form.  But a more insidious kind of bot exists. These are bots that reside ON your computer.  They are like a virus, in that they use your computer, but they are almost undetectable by most anti-virus software.  You may notice that your system will slow way way way down at times, with a lot of unexplained drive and internet activity in the middle of the night (or other times) - this can be an indication of a bot infestation, that could be using your PC to send millions of spam emails or worse.  If your system becomes bot infested, you are responsible for what happens.  Usually, your internet service provider will simply turn off your connection without notice, which can be quite traumatic if your business depends on the internet.

Here are some tips to help prevent this: First, it is generally a bad idea to leave your computer on over night - this creates an unlimited opportunity for attacks from the web.  Continuous systems are an attractive target.  Second, make sure you have your operating system fully updated, with tight security settings.  Third, make sure you have the latest antivirus software installed, with automatic updates - CA's antivirus product is recommended (and available for free download).  Forth, you may want to turn on an IP monitor, to see what you system is doing from the outside.  One such free service is www.ProjectHoneyPot.org, which will monitor your IP address (which would be all of your home/office PCs if you run through a wireless router), and send you email reports of any unusual activity.  After all, knowing is half the battle!  Once you know that there is unauthorized activity, you can seek help to resolve it, before your ISP blocks you!

10 Tips for Using Microsoft PowerPoint

Microsoft PowerPoint 2007 (or any version, such as PowerPoint 2003) can be an extremely effective tool when presenting an idea to a group or single person. PowerPoint allows you to create a visually capturing medium that allows you to convey your idea and hopefully accomplish your goal. Although PowerPoint is a great tool, it can be used in a manner that depreciates the quality of your work and conceal the purpose of your presentation. Using huge amounts of numbers, speaking over your slides, not coordinating your colors can lead to disaster when presenting your work. We’ve compiled a list of 10 tips for using Microsoft PowerPoint so that you can become a communications guru.

PowerPoint can be a provocative, compelling and persuasive business tool. “It can be the very best friend you have,” says Cherie Kerr, a Santa Ana, CA. public relations consultant. “But you have to use it right.” PowerPoint let you create and view full-featured presentations that incorporate, slides, graphics, audio and video that can make a business deal. When used properly, it’s one of the best software presentation tools on the market.

1. Compelling, but not Autonomous
PowerPoint can either make or break a presentation. Because of PowerPoint’s ease of use, many people rely completely upon it and add very little to the presentation. Once you have created your presentation, make sure you create compelling dialogue to go along with your presentation.

2. K.I.S.S
We’ve all heard of K.I.S.S (Keep it Simple Stupid), and that’s what you have to do with PowerPoint. When you’re creating your presentation, make use of simple charts and graphics that reflect what you are speaking about. Don’t create a presentation with long lists of jargon, you will loose most of your audience and render your presentation – ineffective.

3. Don’t Repeat what You See
When you are giving your presentation, don’t repeat what you see. It is extremely boring to sit and listen to someone read their PowerPoint presentation word-for-word. If this is what you’re going to do, save your audience and yourself the time and email the presentation to them.

4. Less is More
PowerPoint is a fantastic communications tool, however there are some aspects you should keep away from. You should not overwhelm your viewers with large amounts of numbers and figures. This tends to create a numbing effect and you will lose many of your viewers. Instead, use simple charts or graphics and if more information needs to be communicated in greater detail, create handouts, but don’t hand them out until the end of your presentation.

5. Never Talk on top of your Slides
When you advance to a new slide, allow your viewers to read your slide before you begin your dialogue. This allows your viewers to absorb the information of the slide then focus their full attention on you for additional content.

6. Color is the Key
It has been scientifically proven that various colors effect people in various ways and induces various moods. Creating a contrast between the colors of your text, background and graphics can help you convey your idea more effectively and affect your audience on an emotional level.

7. Give your Audience a Break
Not all people are alike and some absorb more information verbally rather than visually. Give your audience a visual break - add a blank slide into your presentation at a point where you can explain a little more in detail of your idea or to take questions.

8. Don’t Only use PowerPoint’s Photos and Graphics
You can add a deeper level of interest by adding photos, graphics and video from outside sources. By adding additional external content, you create a complete multimedia experience for your viewer, which in turn, keeps their attention longer and helps them to retain more information.

9. Edit and Edit again!
Once you complete you draft of your presentation, edit it at least three times. And if possible, ask someone to be your guinea pig and let you practice your presentation with him or her. Ask for feedback and if something is unappealing, confusing or distracting, change it.

10. Save the Handouts for Last
What’s worse than trying to give your presentation and your audience is talking about what’s in your handout. Once your audience has the handout, many come to the conclusion that everything they need is in the palm of their hand. This may be true, but you want to keep your audience’s full attention. So save the handouts for last.

PowerPoint is a powerful communication tool, when used properly. You can incorporate audio, video, graphics and text into a medium that can be extremely pleasing and informative to the viewer. Take the time to experiment with PowerPoint and it’s features so when its time to give your next presentation, you’ll be at the top of the class.

Cleaning Your LCD Monitor
or TV

Now that you have your new LCD Monitor or Widescreen TV, it is important to use the right products to clean it.  The wrong cleaner can damage the surface of your display.  However, there are many new cleaning products on the market designed especially for LCD displays. We recommend using a soft, lint-free cloth and a special LCD cleaner.  (You can also use a cleaner that contains any of the following:  Water, Vinegar (mixed with water), Isopropyl alcohol, or Windex mixed with water). 

BUT Do Not Use cleaners that contain any of the following agents: Acetone, Ethyl alcohol, Ethyl acid, Ammonia, Methyl chloride! 

Important: Do not spray any liquids directly on the LCD screen. Always apply the solution to your cloth first, not directly to the parts you are cleaning. Always use a soft cotton cloth. Some materials, such as paper towels or old rags can cause scratches and damage the LCD screen.

The Font Monster!

Watch out for Fonts!  Fonts are Windows' major Achilles' heel.  You may love to print, and think that the one who has the biggest font collection wins, but fonts can slow your Windows system down to a crawl.....  Generally, it is a good idea to keep the number of fonts installed to a maximum of 500 (font files) or less.  And, you should own and use a registry cleaner (see below RegCure) if you ever uninstall fonts to keep your system running at peak performance!

Turning Off Your Printer

Today's electronics are deigned to be safe and economical to operate.  However, leaving devices on 24/7 does eat a substantial amount of electricity, regardless of the device.

Power adaptors are notorious for using more power than the device itself.  This is especially true of cell phones, for example.

It comes down to how much you're going to be printing. Most people usually use their computers off and on all day, so they leave them on all day and then just turn them off at night to save some power and also for safety reasons.  All-in-One printers may also be used as a fax, so they need to stay on all the time regardless

If you're going to be printing off and on all day long, you might as well just keep the printer on until you're completely finished. If you're just going to print one item now and then, and then not print for a few hours, turn it off.   Most printers turn on very rapidly, without long warm up cycles.

The main two reasons to turn your print off are: electricity usage and ink cartridge print heads drying out. The bigger of the two issues may be the drying of the print heads, because inkjet printers really don't use that much electricity. The newer ones use even less, but older printers (unless a laser printer) don't really use that much either.

Most ink cartridges have some sort of a capping mechanism that saves the head from any outside air that may come through when the printer is turned off. But, if you leave the printer turned on all the time when not using it, you're just asking for your cartridges to dry out, and will have to buy another cartridge that much sooner than normally would be the case. If your print heads dry up or clog, your printing quality will suffer also.

Therefore, always make sure you turn your printer off when not using it.  But remember to turn off your printer by the On/Off button, and not by flipping your power strip or UPS. When you use the printer's own On/Off switch, the printer will engage its capping mechanism to prevent cartridge dry-out. Otherwise, it will freeze in whatever state it was in, and your cartridge will still be at risk for drying out.
