How To Speed Up Your Broadband Internet
Here are Registry Tweaks and Scroll down to see Patches
1.Increase bandwidth by tweaking QoS in Windows XP Pro
The following tweak applies only to Windows XP Professional edition.
The default system behavior is that all 100% bandwidth is available, however, if there is a running application that indicates to the OS it needs to send high priority/real time data, then as long as it has the socket open, Windows XP will restrict “best effort†traffic to 80% of the bandwidth so that high priority traffic can be accommodated. Basically, applications can make this request to the operating system for QoS support using the QoS application programming interfaces (APIs) in Windows and this only applies if a specific app is requesting QoS.
If you'd like to change how much bandwidth is reserved for QoS (the default is 20% of the total bandwidth), do the following:
1. Make sure you're logged in as "Administrator" (not just any account with admin privileges).
2. Navigate to START>Run and type: gpedit.msc
3. Navigate to Local Computer Policy > Administrative Templates > Network > QOS Packet Scheduler
4. In the right window, double-click the limit reservable bandwidth setting
5. On the setting tab, check the enabled setting.
6. Where it says "Bandwidth limit %", change it to read 0 (or whatever percentage you want to reserve for high priority QoS data)
7. Click OK, close gpedit.msc
Under START > My Computer > My Network Connections > View Network Connections, right-click on your connection and under Properties (where it lists your protocols), make sure QOS Packet Scheduler is enabled.
The tweak desribed below helps boost priority for DNS & hostname resolution in general. What this means is, it helps web pages load faster, and has negligible effect on downloads (not counting the couple of ms gain with the host resolution at connect-time).
Applying this tweak assumes some proficiency in editing the Windows Registry using Regedit (Start > Run > type: regedit). As always, backup your Registry before making any changes so you can revert to the previous state if you don't like the results.
2.Host Resolution Priority Tweak
host name resolution priority
Windows 2k/XP
First, open the Windows Registry using Regedit, and (after backing up) navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Tcpip\ServiceProvider
Note the following lines (all hex dwords):
Class = 008 (8) - indicates that TCP/IP is a name service provider, don't change.
LocalPriority = 1f3 (499) - local names cache
HostsPriority = 1f4 (500) - the HOSTS file
DnsPriority = 7d0 (2000) - DNS
NetbtPriority = 7d1 (2001) - NetBT name-resolution, including WINS
What we're aiming to do is increase the priority of the last 4 settings, while keeping their order. The valid range is from -32768 to +32767 and lower numbers mean higher priority compared to other services. What we're aiming at is lower numbers without going to extremes, something like what's shown below should work well:
Change the "Priority" lines to:
LocalPriority = 005 (5) - local names cache
HostsPriority = 006 (6) - the HOSTS file
DnsPriority = 007 (7) - DNS
NetbtPriority = 008 (8) - NetBT name-resolution, including WINS
Windows 9x/ME
The tweak is essentialy the same as in Windows 2000/XP, just the location in the Registry is slightly different. For a more detailed description see the Windows 2000/XP section above.
Open the Windows Registry using Regedit, and (after backing up) navigate to:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic es\VxD\MSTCP\ServiceProvider
You should see the following settings:
Class=hex:08,00,00,00
LocalPriority=hex:f3,01,00,00
HostsPriority=hex:f4,01,00,00
DnsPriority=hex:d0,07,00,00
NetbtPriority=hex:d1,07,00,00
The "priority" lines should be changed to:
LocalPriority=hex:05,00,00,00
HostsPriority=hex:06,00,00,00
DnsPriority=hex:07,00,00,00
NetbtPriority=hex:08,00,00,00
Reboot for changes to take effect.
In addition to the tweaks already covered in Win 2k/XP Registry Tweaks and More Win 2k/XP Tweaks, the Windows XP Service Pack 2 introduces a few new issues covered in the article below. Please make sure you understand what you are doing before making any changes to your Operating System. Note the information below only applies to Windows XP Service Pack 2.
3.Remove the limit on TCP connection attempts
Windws XP SP2 introduces a few new twists to TCP/IP in order to babysit users and "reduce the threat" of worms spreading fast without control. In one such attempt, the devs seem to have limited the number of possible TCP connection attempts per second to 10 (from unlimited in SP1). This argumentative feature can possibly affect server and P2P programs that need to open many outbound connections at the same time.
Rant: The forward thinking of Microsoft developers here is that you can only infect 10 new systems per second via TCP/IP ?!?... If you also consider that each of those infected computers will infect 10 others at the same rate:
second 1: 1+10 computers
second 2: 10+10*10 computers (110 new ones)
second 3: 10+100*10 computers ( 1110 new ones)
second 4: 10+1000*10 computers (11110 new ones)
....
all the way to 10*60 + 10^60 computers in a single minute (that's a number with 60 digits, or it would far exceed Earth's population). Even if we consider that 90% of those computers are unreachable/protected, one would still reach ALL of them within a minute.
In other words, even though it is not going to stop worm spreading, it's going to delay it a few seconds, limit possible network congestion a bit, and limit the use of your PC to 10 connection attempts per second in the process ! I have no problem with the new default setting limiting outbound connection attempts. Still, users should have the option to easily disable or change this setting. I might be going out on a limb here, but ever since the introduction of Windows XP I can't help thinking that I dislike all the bult-in Windows "wisardry" in a sense that the system also limits user access. That irritating trend to ease the mental load on end users is somewhat insulting, considering that Windows is to make the more "intelligent" choice instead of the end user, as well as limit their access to tuning such settings...
End of rant.
With the new implementation, if a P2P or some other network program attempts to connect to 100 sites at once, it would only be able to connect to 10 per second, so it would take it 10 seconds to reach all 100. In addition, even though the setting was registry editable in XP SP1, it is now only possible to edit by changing it directly in the system file tcpip.sys. To make matters worse, that file is in use, so you also need to be in Safe mode in order to edit it.
You only need to worry about the number of connection attempts per second if you have noticed a slowdown in network programs requiring a number of connections opened at once. You can check if you're hitting this limit from the Event Viewer, under System - look for TCP/IP Warnings saying: "TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts". Keep in mind this is a cap only on incomplete outbound connect attempts per second, not total connections. Still, running servers and P2P programs can definitely be affected by this new limitation. Use the fix as you see fit.
To change or remove the limit, you can use the following program:

4. Recommended settings for Windows 2000 / XP
Windows 2000 & XP, unlike NT supports large windows as described in RFC1323 ( the 'RcvWindow' has a maximum value of 2**30 rather than 64K), and includes some other improvements over its predecessors you can use to speed up any TCP/IP transfers. , the descriptions and other options are added to provide you with better understanding and enable you to customize your settings.
All the following entries, unless otherwise noted should be placed in the Windows 2000/XP Registry under the key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Tcpip\Parameters
TCPWindowSize
The value of TCP Window in the Windows 2000 Registry is DWORD, representing number of bytes, with range from 0 to 2^30. The recommended values (in red) optimize TCP for any high speed Internet connection and work best in most cases, however if you'd like to use a custom value follow these guidelines:
For best results, the TCPWindow should be a multiple of MSS (Maximum Segment Size). MSS is generally MTU - 40, where MTU (Maximum Transmission Unit) is the largest packet size that can be transmitted. MTU is usually 1500 (1492 for PPPoE connections). To determine the MTU value of your ISP, check out the Advanced Registry Editing section of our site.
There are three places in the Windows 2000 Registry where you can add the TCP Window parameter.
HKLM/SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
GlobalMaxTcpWindowSize="256960" (DWORD, number of bytes) Valid range is from MSS to 2^30. Add the value as a decimal. Note: For best results RWIN has to be a multiple of MSS lower than 65535 times a scale factor that's a power of 2, i.e. 44 x 1460 = 64240 x 2^2 = 256960. If you choose to use a RWIN lower than 65535, you can simply make it multiple of MSS and turn scaling off (Tcp1323Opts=0)
HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Param eters
TcpWindowSize="256960" (DWORD, number of bytes) Valid range is from MSS to 2^30. Add the value as a decimal. TcpWindowSize can also exist under TcpipParametersInterface - if added at this location, it overrides the global setting for this particular . Note (10/20/00): Seems MS has found another bug in Windows 2000, the TCPWindowSize should be configured with the global setting (GlobalMaxTcpWindowsSize) rather than this one - Q263088
Note: For best results RWIN has to be a multiple of MSS lower than 65535 times a scale factor that's a power of 2, i.e. 44 x 1460 = 64240 x 2^2 = 256960. If you choose to use a RWIN lower than 65535, you can simply make it multiple of MSS and turn scaling off (Tcp1323Opts=0)
Tcp1323Opts
Tcp1323Opts is a necessary setting in order to enable Large TCPWindow support as described in RFC 1323. Without this parameter, the TCPWindow is limited to 64K.
HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Param eters
Tcp1323Opts="1" (DWORD, recommended setting is 1. The possible settings are 0 - Disable RFC 1323 options, 1 - Window scaling but no Timestamp options, 3 - Window scaling and Time stamp options.)
Note: Tcp1323Opts="3" might help in some cases where there is increased packet loss, however generally you'll achieve better throughput with Tcp1323Opts="1", since Timestamps add 12 bytes to the header of each packet.
DefaultTTL
DefaultTTL determines the time in seconds and the number of hops a packet lives. While it does not directly affect speed, a larger value increases the amount of time it takes for a packet to be considered lost, discarded and retransmitted. A value that's too small can cause packets to be unable to reach distant servers at all.
HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Param eters
DefaultTTL="64" (DWORD, recommended setting is 64. Other settings that are widely used are 128 and 32)
EnablePMTUDiscovery
When set to 1 (True), TCP attempts to discover MTU automatically over the path to a remote host. Setting this parameter to 0 causes MTU to default to 576 which reduces overall performance over high speed connections. Note that this setting is different than our Windows 9x recommendation.
HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Param eters
EnablePMTUDiscovery="1" (DWORD - boolean, valid settings are 0-->False and 1-->True. Many connections perform better with this entry at 1, however, if you prefer to set your upstream to send fixed 1500 packets, you might want to use 0 instead). When set at 1, establishing connections and initial transfer speed might slow down a bit, however you will get better throughput if somewhere in the path large packets need to be fragmented.
EnablePMTUBHDetect
Setting this parameter to 1 (True) enables "black hole" routers to be detected, however it also increases the maximum number of retransmissions for a given segment. In most cases you'd want to keep BHDetect to 0 (False).
HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Param eters
EnablePMTUBHDetect="0" (DWORD - boolean, valid settings are 0-->False and 1-->True. Recommended setting is 0)
SackOpts
This parameter controls whether or not SACK (Selective Acknowledgement) support is enabled, as specified in RFC 2018. SACK is especially important for connections using large TCP Window sizes.
HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Param eters
SackOpts="1" (DWORD - boolean, recommended setting is 1. Possible settings are 0 - No Sack options or 1 - Sack Option enabled).
TcpMaxDupAcks
This parameter determines the number of duplicate ACKs that must be received for the same sequence number of sent data before "fast retransmit" is triggered to resend the segment that has been dropped in transit.
HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Param eters
TcpMaxDupAcks="2" (DWORD - range 1-3, recommended setting is 2).

3. winxp_dnscache.zip
Description: Patch Windows 2k/XP not to cache failed DNS entries. By default, when a DNS lookup fails (due to temporary DNS problems), Windows still caches the unsuccessful DNS query, and in turn fails to connect to a host regardless of the fact that the DNS server might be able to handle your lookup seconds later. This patch fixes the problem by configuring the DNS client to continue sending queries to an unresponsive network. To install, save to your HD, unzip the .reg file, then double-click the filename.
Web Patches - faster loading of Web Pages
The following patch increases Web page loading speed, by doubling the number of possible concurrent open connections. For example, imagine a web page has 20 images and some text - in order for your browser to get all these files, it opens 2 or 4 concurrent connections, depending on the Web server. Increasing the number of open connections allows for faster retrieving of the data. Please note that the patch sets some values outside of the HTML specs. If you decide to install it, backup your Registry first. Changes will take effect after you reboot. Download the patch appropriate for your OS:

By default, when a DNS lookup fails (due to temporary DNS problems), Windows still caches the unsuccessful DNS query, and in turn fails to connect to a host regardless of the fact that the DNS server might be able to handle your lookup seconds later. This patch fixes the problem by configuring the DNS client to continue sending queries to an unresponsive network. To install, save to your HD, unzip the .reg file, then double-click the filename.
Web Patches - faster loading of Web Pages
The following patch increases Web page loading speed, by doubling the number of possible concurrent open connections. For example, imagine a web page has 20 images and some text - in order for your browser to get all these files, it opens 2 or 4 concurrent connections, depending on the Web server. Increasing the number of open connections allows for faster retrieving of the data. Please note that the patch sets some values outside of the HTML specs. If you decide to install it, backup your Registry first. Changes will take effect after you reboot. Download the patch appropriate for your OS:

List Of Useful Windows XP Keyboard Shortcuts
Keyboard shortcuts are a great way to keep things moving when you're using your computer, and they let you perform tasks without lifting your hands from the keyboard. These are some of the basics that you should know--at least if you want to cut down on the number of times you reach for the mouse every day.1. Ctrl Alt Del is the mother of all keyboard shortcuts, affectionately known as the "three-fingered salute," since it's so useful when your Windows box locks up. Pressing the combo once (simultaneously) opens the Windows Task Manager. (From within the Task Manager, you can force-quit a crashed program, see a list of processes or applications running on your machine, check performance parameters such as how hard your CPU is working, or track your network usage.) Is your machine totally locked up? Reach over, grab the mouse and click Shut Down.
2. Ctrl S saves the file you're working on. Ever lost your homework, a spreadsheet at work, or some video you've been editing? Hit Ctrl S (simultaneously) to save. Hit it early and often! (Want to open a file from within the program you're running? Ctrl O universally opens the File/Open window.)
3. Ctrl C copies text, files, or icons that you've highlighted, Ctrl V pastes them where you point your mouse (hey, you can't completely eliminate using it), and Ctrl X cuts whatever you've highlighted out of the document (or folder, photo, movie clip, or whatever it is you're working on). Ctrl A highlights the entire file you're working on or everything in a folder or on your desktop.
4. Alt Tab lets you switch on the fly between all of your open windows. Press the combination once to switch to your last open window or multiple times to switch to any other open window. Holding down Alt Tab will bring up a system window that shows you what apps are running and which one you're switching to.
5. Ever wonder why almost every Windows program has the F in File underlined, not to mention the E in Edit, and so on so forth across the top of the Window? Hit Alt that letter to open that particular menu; you can either use the arrow keys to move around within that window, or keep your eyes peeled for more underlined letters to use more Alt key combinations.
6. The Windows key (the one that looks like the Windows logo, or a flag) R opens the Run dialog. From here, you can launch a command-line window by typing cmd, but you can do a lot more. You can, for example, paste in a folder path, such as C:\Documents and Settings\[username]\My Documents\Expenses, and Windows will open it automatically. You can also use the Run dialog to open Microsoft applications such as Word, Excel, or Notepad. Just type winword to launch Word, type excel to launch Excel, and notepad to launch Notepad.
7. Windows E launches Windows Explorer, defaulting to My Computer.
8. F2 renames a selected file or folder. (This is so much easier than right-clicking!)
9. F3 launches Search if you're on the desktop or in a folder.
10. Windows M minimizes all open windows, and Windows D shows your desktop. (These results look similar, but they're slightly different; Windows M minimizes all windows that support the command, while Windows D actually raises the desktop to the top.) This is a great one for when the boss pops up in your cubicle. Once the boss gone, hit Shift Windows M to bring up your minimized windows, or Windows D to drop your desktop back down again.
How To Download Music For Free Using Windows Media Player
Are you scared that the RIAA is about to track you down for illegally downloading songs.
Well, here is a method of obtaining many songs absolutely free that is virtually untrackable
by modern technology. This has to do with capturing streaming audio, which in many cases, believe it or not
are plain old mp3s just waiting for you to "download." I have found most of the current top-40 as well as many others you may like, so keep searching. The music is waiting for you to find it.
Step 1:
First of all, you need to find a good site that hosts streaming audio. My favorite that has brought me many songs to date is hxxp://www.windowsmedia.com . Some others are just as good, but this is the site that I will be referencing (plus, I know you guys love to steal from Microsoft).
Step 2:
Alright, go up to the left hand corner where there is an empty text box. This is the search box, just fill it with a songname or artist just like you would in kazaa and click search. This will bring up a page with links to many websites hosting a stream by that artist. The ones with music notes are just that...music, this is what you want. In many cases, this is all you need. Just right click on one of the links and click "save as" to save the song. This works if the file extension is .mp3 or .wma or .asf or well-other known formats. If this worked, you are finished, otherwise continue reading.
Step 3:
However, if you encounter a .asx file, there are a few more steps you will have to endure. First of all, do exactly like the above example and save the file locally. After the file is downloaded, check to see how large the file is. If it is a large file in the megabyte range, then you should be able to play it in your favorite music program. However, if it is less than 1 kilobyte, open it as a textfile. You will then see many script commands that communicate to windows media player. Don't worry about these, just look for some URLs which will most likely be pointing to a .asf file. It will have at least one if not more. Open the new found URL in your browser and save it like in step 2 and you should be good to go. (I use Mozilla, because Internet Explorer likes to open things rather than save them as I tell it)
NOTE: If any of the URLs are preceded with "mms://" instead of "http://" find another URL, because this technique will not work.
This technique is especially useful to avoid prosecution because streaming audio, and downloading it appear the same to a web server, therefore you are seen as just another "legal" listener, so "download" away my friend and don't blame me if this soon becomes illegal (if it isn't already).
Step 4:
If you are picky then search for a program that will convert these file types to mp3s. I assure you there are many sites out there.
If this technique does not work for some reason, there is another technique which is manually recording streaming audio, with an audio capture program. I use the one that came with my soundcard (Audigy 2ZS, great soundcard), but I would recommend it only as a last resort such as with "mms://" files. There is a degredation in quality compared to the other formats and it records every sound your PC makes while it is recording so don't chat on AIM while recording (lol I can hear random doors slamming now).
