False Windows XP Tweaks

Myths/False Tweaks


Prefetch settings, many people say the default setting is 228: 228 = 4x, 448 = 8x, 8 16x 16x, 1344 = 24x, 1792 = 32x, 2240 = 40x, 2688 = 48x

Or in your *.reg file...


Contiguous File allocation size

This setting optimizes the file system by specifying the minimum amount of free contiguous space needed before writing a file. Larger values are especially useful for disk intensive applications to reduce fragmentation. After making this change you will want to defragment your hard drive.

Create a DWORD value named 'ConfigFileAllocSize' and set the value to '200' (in hex) or 512 (decimal)

If you're into things like video editing which opens large files constantly you will want this setting to be higher. For most of us this lower value is what you will want. In most cases this is a better than default Contiguous file allocation size.

Increase BROADBAND speed in WinXP *Should work for 56k also*

1. make sure your logged on as actually "Administrator". do not log on with any account that just has administrator privileges.
2. start - run - type gpedit.msc (not available in home version)
3. expand the "local computer policy" branch
4. expand the "administrative templates" branch
5. expand the "network branch"
6. Highlight the "QoS Packet Scheduler" in left window
7. in right window double click the "limit reservable bandwidth" setting
8. on setting tab check the "enabled" item
9.where it says "Bandwidth limit %" change it to read 0

Effect is immediate on some systems, some need to re-boot. This is more of a "counter what XP does" thing. In other words, XP seems to want to reserve 20% of the bandwidth for its self, even with QoS disabled. So why not use it to your advantage. To demonstrate the problem with this on stand alone machines start up a big download from a server with an FTP client. Try to find a server that doesn't max out your bandwidth. In this case you want a slow to medium speed server to demonstrate this. Let it run for a couple of minutes to get stable. The start up another download from the same server with another instance of your FTP client. You will notice that the available bandwidth is now being fought over and one of the clients download will be very slow or both will slow down when they should both be using the available bandwidth. Using this "tweak" both clients will have a fair share of the bandwidth and will not fight over the bandwidth.

OR you could just uninstall it ;)

Increase your cable modem or DSL speed in XP

This tweak is for broad band cable connections on stand alone machines with winXP professional version - might work on Home version also. It will probably work with networked machines as well but I haven't tried it in that configuration. This is for windows XP only, it does not work on win2000. I use 3 Com cards so I don't know how it works on others at this point. It does not involve editing the registry. This tweak assumes that you have let winXP create a connection on install for your cable modem/NIC combination and that your connection has tcp/ip - QoS - file and print sharing - and client for microsoft networks , only, installed. It also assumes that winxp will detect your NIC and has in-box drivers for it. If it doesn't do not try this. In the "My Network Places" properties (right click on the desktop icon and choose properties), highlight the connection then at the menu bar choose "Advanced" then "Advanced Settings". Uncheck the two boxes in the lower half for the bindings for File and Printer sharing and Client for MS networks. Click OK

1. From the windows XP cd in the support directory from the support cab, extract the file netcap.exe and place it in a directory on your hard drive or even in the root of your C:\ drive.
2. next, open up a command prompt window and change directories to where you put netcap.exe. then type "netcap/?". It will list some commands that are available for netcap and a netmon driver will be installed. At the bottom you will see your adapters. You should see two of them if using a 3Com card. One will be for LAN and the other will be for WAN something or other.
3. Next type "netcap/Remove". This will remove the netmon driver.
4. Open up control panel / system / dev man and look at your network adapters. You should now see two of them and one will have a yellow ! on it. Right click on the one without the yellow ! and choose uninstall. YES! you are uninstalling your network adapter, continue with the uninstall. Do not restart yet.
5. Check your connection properties to make sure that no connection exists. If you get a wizard just cancel out of it.
6. Now re-start the machine.
7. After re-start go to your connection properties again and you should have a new connection called "Local area connection 2". highlight the connection then at the menu bar choose "Advanced" then "Advanced Settings". Uncheck the two boxes in the lower half for the bindings for File and Printer sharing and Client for MS networks. Click OK.
8. Choose connection properties and uncheck the "QOS" box
9. Re-start the machine
10. after restart enjoy the increased responsiveness of IE, faster page loading, and a connection speed boost.
