Play sound and video

Have you ever encountered problems trying to play a movie? Or making a list of favorite songs? For example, instead of using only Windows Media Player, maybe you should go for two different programs.
For example, I use BS Player to watch movies and videos, and Winamp when I listen to music or radio. Both these programs are faster and more intuitive than the classic Media Player.
Of course, you should also have some good and comprehensive codecs. I use K-Lite Codec Pack. It is very good(it also works for Windows Media Player).

Improve visual appearence

Have you ever been displeased with the way Windows XP looks? Here are a few possibilities to improve the visual appearence and to make Win XP look more appealing.
Vista Transformation Pack - this program will transform your Windows user interface to ultimate Windows Vista alike looks that everyone will never notice it's the same old Windows XP
VistaMizer - It does not provide own files and change your system files. That has the advantage that VistaMizer works with each language and no changes of the language specifics are made.
Style XP - It is not a skinning engine. It uses Microsoft's built-in visual style engine, but enhances it by providing many useful tools. Style XP can import, select, rotate, and manage themes, visual styles, wallpapers, logons, bootscreens, icons, and explorer bar. Style XP includes its own visual styles.

Above, I've written part of the publisher's description. I leave it to you to decide if it matches the real thing or if it could be classified as rubbish :).
The Vista Transformation Pack and VistaMizer have the advantage of being free programs. Instead, Style XP, in my opinion, looks the best and acts like it. It's up to you to decide which one it's better for yourselves

The advantage of using RevConnect over the normal DC++

RevConnect is a file sharing program based on DC++.
Download one file from multiple users at the same time without corruption! This can vastly improve your download speeds. Every download chunk is combinable and dividable and has elastic size decided by download speed.

Does anyone use it? I've been using RevConnect for the past 2 years and I am thrilled with it. It'a a major improvement of the normal DC++, since I download from more than 1 user at the same time (sometimes I download from over 100 users) and the speed is incredible

The best browser is ...

Let's now settle on the best browser for the internet. Now I use Mozilla Firefox, sometimes I open an website with Opera or Avant and almost never with Internet Explorer.

What do browser do you use? What you like at that browser? Do you need any advice on switching to another one? Let me know

Which software do you think is a "must have" for PC?

Let's find out what software is necessary for our computers. I would start with an antivirus and continue with something to clean up the registry structure and the hard drive.
