DLL Files


A Dynamic Link Library (DLL) is a file of code containing functions that can be called from other executable code (either an application or another DLL). Programmers use DLLs to provide code that they can reuse and to parcel out distinct jobs. Unlike an executable (EXE) file, a DLL cannot be directly run. DLLs must be called from other code that is already executing.
In more understandable words, a DLL is a file which does a particular job, and allows other programs to use its efforts in assisting the program's job. Some programs use a DLL so that they won't need to spend time figuring out how to do that job. For example, Microsoft has a DLL comctl32.dll which does all the user interface jobs (toolbars, text boxes, scroll bars, etc). So, other programs use that DLL so they won't have to create their own edit boxes, etc. When a program requires a DLL to run, and can't find it, it won't be able to run because its suddenly missing the DLL to perform some of its critical work. We've all used DLLs before and we're using them now. They're required to run all Windows programs, including Windows but you never actually see them at work. There are different versions of the same file name. Just because the file appears to be the same doesn't mean it is. To check what version the file is, open Windows Explorer, locate the file and right click on it. Select Properties and click on the Version tab If there is no version tab then the file does not have a version number. Generally, if you have a newer version of a file, don't replace it with an older version.

5 tips to speed up your computer


Here are my top five tips to keep your computer running smoothly.

1. Defragment your hard drive

If, like me, you tend to move your files around a lot then Windows can become a bit messy, with fragments of these files stored at different locations of your hard drive. This means your computer has to put in extra effort to find all these bits and pieces and it slows down the performance of the system.
Fortunately, Windows has a built in system to combat this problem called Disk Defragmenter.
Open My Computer,
Right-click once on your C: Drive and go down to “Properties”
Select the “Tools” tab and click “Defragment Now”. Then simply  follow the step by step instructions.

2. Clean your startup folder

As your computer gets older and you install more and more programs onto your hard drive, many of these add themselves to the Windows Start-up folder. Then every time you boot your computer, the load time is slowed down while each of these programs loads. Just think how fast your computer could start if you only had the essential programs loading at boot. Here’s how to fix the problem.
Click “Start”, then “Run” and type “MSCONFIG” into the box. Navigate to the “Startup” tab and note each program with a tick in the box next to it. These are the ones loading at startup. Assess each one and ask yoruself if it’s essential that it loads every time your computer boots. If it isn’t, simply the box. Do this until you’re happy with your selection, then reboot to complete the process. You should notice a considerable change in boot time.

3. Get rid of spyware

Spyware is one of the most common problems facing today’s computer users. They’re stealthy programs that insert themselves into your registry without permission and slow down your system. They’re usually found within ‘free’ programs that you’re trialling, or on suspect websites. If left to do as they please they can do serious damage to your file system and slow your computer down to snail’s pace, so it’s best to catch them early and get rid.
There are plenty of anti-spyware programs out there, some of them are even free, so go to google and find yourself a good anti-spyware program and rid your computer of those nasty pests.

4. Clear space on your hard drive

If your hard drive is more than 90% full you’ll notice a dramatic slow down in the speed of your computer. This is perhaps the easiest problem to remedy. Simply delete any files or folders you no longer need and uninstall old programs you don’t use anymore.

5. Clean your bloated registry

When you uninstall a program via the control panel, it often leaves behind entries that clog up your registry and slow it down. Windows gets distracted while carrying out operations and doesn’t know what to do with these leftover entries, resulting in poo application loading times, extremely slow shut down and boot times and at times your system freezing up completely,  so it’s best to remove them. You can do this by downloading a free registry cleaner like ccleaner that will do all the work for you. It will also kill two birds with one stone by deleting your cache.
By taking these 5 simple steps you will have significantly increased the speed of your computer and improved its health at the same time. All completely free of charge!

What does software mean ?

Computer software (also known as soft or program) is a general term used to describe a collection of computer programs, procedures and documentation that perform some tasks after being installed on a computer system. Without software a computer is practically unusable because hardware cannot communicate without software support. The soft may be classified in two major classes:  paid (commercial) programs and free (open source, GNU etc.) software. You can find here free reviews and advice about how to choose paid programs and free software.

What is a Crack?

The word "crack" in this context means the action of removing the copy protection from commercial software. A crack is a set of instructions or patch used to remove copy protection from a piece of software or to unlock features from a demo or time-limited trial. There are crack groups who work together in order to crack software, games, etc. If you search for Real Player Crack, you will often see the word "crack" amongst the results which means it is the full version of the product.
