Create great graphics with Paint.NET 4.0

One of the things I like to do besides repairing computers is creating graphics. Over the years I have used many different image editing programs, including Photoshop and CorelDraw. Recently, one of my favorite freeware image editing programs, Paint.NET, released a new version. Let's take a look at what's new in Paint.NET 4.0.

Paint.NET was originally created in 2004 to be a replacement for the Paint program that is included inside Windows, but has evolved into much more since then. It now includes such features as layers, effects, transparency, blending and best of all, plugins. With hundreds of plugins available, you can really expand on the out-of-the-box graphic capabilities of Paint.NET. Since I have a digital camera that will take photos in RAW format, I found a plugin that opens that type of file. I also use Photoshop and have found a plugin to open those files too.

Paint.NET 4.0 now has a brand-new rendering engine (asynchronous and fully multi-threaded) and supports hardware acceleration via the GPU (Graphics Processing Unit). Selections are now anti-aliased and selected outlines are rendered with 'dancing ants' animation, greatly improving the contrast between selection and image. And the user interface has also been revamped to include a Settings dialog box for easier configuration.

Now the only down side to Paint.NET 4.0 is the system requirements. Since this version of Paint.NET is built with the .NET Framework 4.5, it will only run on Windows 7 SP1, Windows 8 or Windows 8.1. It does not run on Windows Vista or Windows RT. Here are the complete system requirements:

  • Windows 7 SP1 or newer is now required.
  • .NET Framework 4.5 is now required, and will be installed if needed.
  • A dual-core (or more!) processor is highly recommended.
  • Hardware acceleration (GPU) via Direct2D is now supported.

How to upgrade your computers hard disk drive to a solid state drive

Most computers (laptop & desktop) nowadays come with a Hard Disk Drive (HDD) as standard equipment with a Solid State Drive (SSD) as an option. Each drive type has its pros and cons: HDD's are cheaper and have more storage, but SSD's are extremely fast (especially when connected to a SATA3 port). So if your existing computer has a HDD, odds are you could replace it with a SSD. Here's how to upgrade your computer hard disk drive to a solid state drive.

How to upgrade your computer's hard disk drive to a solid state drive

I wrote an article not long ago on how to upgrade the hard drive in your computer and will be referring back to it often. It describes how to clone a smaller drive to a larger one of the same type. Since SSD's normally have less storage than HDD's, this time I'll have to shrink the existing HDD (80 GB) partition(s) down below the capacity of the target SSD (64 GB) before I can clone it.

As in the aforementioned article, the first thing to do is a Checkdisk of the existing HDD. Doing this will assure there are no errors that may prohibit the cloning of the drive.

Now we have to start cleaning up the drive. Windows has a built-in tool called Disk Cleanup (cleanmgr.exe) that works pretty well at getting out the clutter. Try using it from an admin command prompt, that way you'll get more options.

Since we are trying to get the maximum amount of free space we can, we will have to delete some files, which may include documents, photos, videos, etc. Doing a backup right now will insure we have a copy of all of the files if we need to recover some later.

Next thing I have to do is find out what is taking up the space on the existing HDD. For this I'll use a copy of SpaceMonger. After quick view, I see I can free up several gigabytes of space by permanently removing the hibernation file and temporarily deleting the swap file. Windows will warn you about having no swap file, but we will be recreating the swap file once the drive cloning is complete.

The next thing we need to do to the drive is to defragment it. I'll use Defraggler from Piriform for this task. Once the drive is defragged, it's time to shrink it. To do this, open Computer Management, expand the Storage section in the left column and select Disk Management. In the right column, right-click on the partition marked as Boot (usually C:) and select Shrink. Remember to take the size down at least 10-15% below the capacity of the new SSD.

Once the partition has been resized, it's time to clone the drive. The following article has all of the details on how to clone you hard drive, including links to the cloning software.

Note: An issue not addressed in the article above is the form factor; the existing HDD is 3.5" form factor and SSD's are normally 2.5" form factor.

This can easily be resolved by using a pair of 2.5" to 3.5" adapter brackets.

Once the drive cloning is complete and the system is running again, we need to expand the boot partition to use any free space that may be available. Open Computer Management, expand the Storage section in the left column and select Disk Management. In the right column, right-click on the partition mark as Boot (usually C:) and select Expand. Once the boot partition has been resized, you can now enable Windows swap file.

Clean up your Internet browser with AdwCleaner

I've been doing virus / malware removal for a while now and have seen allot of different types of infections. The latest trend is to target your Internet browser. Whether it is Internet Explorer, Chrome or Firefox, it can get compromised. One of the best programs I've found to clean up Internet browsers is AdwCleaner developed by Xplode.

AdwCleaner works great for removing adware, PUP's (Potentially Undesirable Program), unwanted toolbars and home page hijacking. It's a stand-alone program (requires no installation) except for the quarantine folder and a few registry entries it creates. Just download it to your desktop and you are ready to go. And you can uninstall it right from the main user interface. Best of all, it's free.

Browser exploits have been around for a while now. Who hasn't had their home page changed or have a mysterious toolbar appear when they opened up their browser? AdwCleaner is the perfect tool for getting all of that junk out of your browser(s). The developer, Xplode, is located in France, so some of the menus are multilingual (English / French).

How to spot a piece of spam e-mail

E-mail has really changed the way we communicate over the last couple decades. The days of pen and paper letter writing are gone. But e-mail does have a negative side: the unwanted e-mail know as Spam. Billions of pieces of spam are sent every day. Do you know how to spot a piece of spam?

When it comes to spam, I like to break them down into two groups: Junk, just plain advertising, and Malicious, which is meant to deliver some kind of payload. Malicious spam can deliver its payload two different ways: either opening the e-mail itself or any attachment(s). I've had quite a few clients that got infected that use Outlook. If you use Outlook and have either the Preview or Reading Pane options turned on, Outlook is opening your mail to generate those views. So, even if you don't open the mail, Outlook still is.

So how do you tell if an e-mail is spam? Here are some tips on how to spot a piece of spam:

The From: field
This field can be easily faked. Do you know the sender? Do you now or in the past done business with that company? If you answered no to both questions, it may be spam. Also, look out for e-mail addresses that come from domains that provide free e-mail addresses (gmail.com, yahoo.com, etc.) or end with a two-letter extension (@com.uk, @com.ru, etc.). Two-letter extensions are for domains outside America.

The To: field
This field should contain just your e-mail address. If there are multiple e-mail addresses listed, do you recognize any of the other e-mail addresses? If you don't, it could be spam. And if this field is blank, the odds are its spam.

The Subject: field
When it comes to the Subject field, if it doesn't sound right, it's not. Spam from other countries is quite often full of grammatical errors. Always remember that if it sounds too good to be true, it probably is. Odds are that e-fax, scan from a Xerox WorkCentre (notice the spelling) or notice to appear in court that is attached is just a virus.

The bottom line is if you question the validity of any e-mail from a person or company, don't open it. Pick up the phone and call them to confirm they sent the e-mail.

How to upgrade or add more memory to your computer

Doing computer repair for a living, I get a lot of questions about how to speed computers up. When it comes to improving the performance of your computer, adding more memory has always been the best 'bang for the buck'. And it's not that hard to do. Here's how to upgrade or add more memory to your laptop or desktop computer.

How to upgrade or add more memory to your computer

When you start to look at upgrading your computer's memory, there are three (3) things you need to know: type of memory it uses, how much memory you currently have and the maximum amount of memory your system can handle. Computer memory is installed into slots on the motherboard. Laptops use SO-DIMM (Small Outline Dual In-line Memory Module) slots and desktops use DIMM (Dual In-line Memory Module) slots. The amount of memory slots varies from laptop (1-2) to desktop (2-8). High performance motherboards, like the ones used in servers, can have 16 or more memory slots.

There are a couple of ways to find out the memory specs of your computer. The first is the tried and true method, the manufacturers manual (either system or motherboard) and physically checking the slots in the computer (some laptops have the memory slots in two different locations). Or you can use an online tool like the Crucial System Scanner to find out what type of memory is in your computer. In some cases, instead of just adding more memory, you may have to replace the existing memory modules with larger ones.

Once you have found out what type of memory you need, it's time to go and purchase it. You can buy it on-line or locally. But remember, if you need to return it, it's easier to do it locally. Also, if you need two or four modules of memory, many vendors offer twin and quad packs of memory for less than the individual price. Once you have your new memory, it's time to install it.

Note: Remember to disconnect the power going to the system before working on it.

  • Desktops - Disconnect the power cord going to the computer
  • Laptops - Disconnect the ac charger and remove the battery (if possible)
