Above 90% computers all over the world run Windows… and hence another computer trick.

FACT
But do you know that about 20% of your internet bandwidth is reserved by Microsoft.
———————————————————————————————————
Uses of Reserved Bandwidth
** Windows Automatic Updates rely on this reserved bandwidth.
** Fast loading Microsoft Websites
** Sending Error Reports
** Online Help support in Microsoft Office
———————————————————————————————————
But this can be recovered back…
———————————————————————————————————
The Remedy
** Start >> Run
** Type gpedit.msc
** This opens the Policy Editor
** Now, Local Computer Policy >> Computer Configuration
** Then, Administrative Templates >> Network
** Now, click on QOS Packet Scheduler
** Now, on Right hand side
** Double Click Limit reservable bandwidth
** Now in Setting Tab

********************* NOTE **********************It says : Not Configured
Reality : The Explain Tab says “By default, the Packet Scheduler limits the system to 20 percent of the bandwidth of a connection”

***************************************************
** So, on Setting Tab select Enabled
** Now, change Bandwidth limit (%) to 0 (Zero)
********************** NOTE ********************Misconcept : This don’t means that you won’t be able to communicate with Microsoft or any its services !!!
Actually : This reserved Bandwidth is only to accelerate Microsoft internet connections more than other connections !!!

****************************************************
** Click OK !!!

That’s All !!!

A firewall is a tool that monitors communication to and from your computer. It sits between your computer and the rest of the network, and according to some criteria, it decides which communication to allow, and which communication to block. It may also use some other criteria to decide about which communication or communication request to report to you (either by adding the information to a log file that you may browse whenever you wish, or in an alert message on the screen), and what not to report.

What Is It Good For?
Identifying and blocking remote access Trojans. Perhaps the most common way to break into a home computer and gain control, is by using a remote access Trojan (RAT). (sometimes it is called “backdoor Trojan” or “backdoor program”. Many people simply call it a “Trojan horse” although the term “Trojan horse” is much more generic). A Trojan horse, is a program that claims to do something really innocent, but in fact does something much less innocent. This goes to the days where the Greek soldiers succeeded to enter through the gates of Troy by building a big wooden horse, and giving it as a present to the king of Troy. The soldiers allowed the sculpture to enter through their gates, and then at night, when the soldiers were busy guarding against an outside attack, many Greek soldiers who were hiding inside the horse went out and attacked Troy from the inside. This story, which may or may not be true, is an example of something which looks like something innocent and is used for some less innocent purpose. The same thing happens in computers. You may sometimes get some program, via ICQ, or via Usenet, or via IRC, and believe this program to be something good, while in fact running it will do something less nice to your computer. Such programs are called Trojan horses. It is accepted to say that the difference between a Trojan horse and a virus, is that a virus has the ability to self-replicate and to distribute itself, while a Trojan horse lacks this ability. A special type of Trojan horses, is RATs (Remote Access Trojans, some say “remote admin Trojans”). These Trojans once executed in the victim’s computer, start to listen to incoming communication from a remote matching program that the attacker uses. When they get instructions from the remote program, they act accordingly, and thus let the user of the remote program to execute commands on the victim’s computer. To name a few famous RATs, the most common are Netbus, Back-Orifice, and SubSeven (which is also known as Backdoor-G). In order for the attacker to use this method, your computer must first be infected by a RAT.
Prevention of infections by RATs is no different than prevention of infection by viruses. Antivirus programs can identify and remove most of the more common RATs. Personal firewalls can identify and block remote communication efforts to the more common RATs and by thus blocking the attacker, and identifying the RAT.
