Speed-up Access to AVI Media Files (Windows XP) AVI加速開啟

Windows XP can run slowly when attempting to access a folder that contains a
large number of AVI (Audio Video Interleave) media files. This tweak speeds
the process up by stopping Windows from extracting file information from AVIs.

System Key: [HKEY_CLASSES_ROOT\CLSID\{87D62D94-71B3-4b9a-9489-5FE6850DC73E}]

To disable file information extraction rename the key and place a minus sign
infront of the current name (i.e. "-{87D62D94-71B3-4b9a-9489-5FE6850DC73E}").

Disable Image Preview (Windows XP) 停用影像預覽

When you open an image file in Windows XP the default action is to "Preview" it
using the Windows Picture and Fax Viewer. This tweak can be used to disable the
Preview image option.

System Key: [HKEY_CLASSES_ROOT\SystemFileAssociations\image\ShellEx\ContextMenuHandlers\ShellImagePreview]
Value Name: (Default)
Data Type: REG_SZ (String Value)
Value Data: Blank or {e84fda7c-1d6a-45f6-b725-cb260c236066}

Clear the value of "(Default)" to disable the default image preview action.
You can restore the preview action by set the value to
"{e84fda7c-1d6a-45f6-b725-cb260c236066}".


Note: This will only remove Preview for image formats that are associated with
an alternate viewer. File types that are associated with Windows Picture and
Fax Viewer will still show the Preview option.

Optimize Broadband Cable Modem and DSL Connections (Windows 2000/XP) 網路加速

Use these settings with your Cable Modem or DSL broadband Internet connection,
to boost network throughput performance with Windows 2000 and Windows XP.

System Key: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
Data Type: REG_DWORD (DWORD Value)

DefaultTTL = "80" hex (or 128 decimal)
Specifies the default time to live (TTL) for TCP/IP packets. The default is 32.

EnablePMTUBHDetect = "0"
Specifies whether the stack will attempt to detect Maximum Transmission Unit
(MTU) routers that do not send back ICMP fragmentation-needed messages. The
default is 0.

EnablePMTUDiscovery = "1"
Specifies whether the TCP/IP stack will attempt to perform path MTU discovery
as specified in RFC 1191. The default is 1.

GlobalMaxTcpWindowSize = "7FFF" hex (or 32767 decimal)
Specifies the system maximum receive window size advertised by the TCP/IP stack.

TcpMaxDupAcks = "2"
Determines the number of duplicate ACKs that must be received for the same
sequence number of sent data before "fast retransmit" is triggered.

SackOpts = "1"
Enables support for selective acknowledgements as documented by Request for
Comment (RFC) 2018. Default is 0.

Tcp1323Opts = "1"
Controls RFC 1323 time stamps and window scaling options. Possible values are:
"0" = disable RFC 1323 options, "1" = window scale enabled only,
"2" = time stamps enabled only and "3" = both options enabled.

TcpWindowSize = "7FFF" hex (or 32767 decimal)
Specifies the receive window size advertised by the TCP/IP stack. If you have a
latent network you can try increasing the value to 93440, 186880, or 372300.

Change the Maximum Transmission Unit (MTU) Size (Windows NT/2000/XP)  加大包

This parameter specifies the Maximum Transmission Unit (MTU) for a network
interface. By optimizing the MTU setting you can gain substantial network
performance increases, especially when using dial-up modem connections.

MTU stands for Maximum Transmission Unit and in basic terms, it defines the
maximum size of a packet that can be transferred in one frame over a network.

System Key: [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\[Adapter ID]]
Value Name: MTU
Data Type: REG_DWORD (DWORD Value)
Value Data: Default = 0xffffffff

Recommended Values

576 - Dial-up Connections
1492 - PPPoE Broadband Connections
1500 - Ethernet, DSL and Cable Broadband Connections

Note: For Windows NT 4 the key is [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\ Tcpip\Parameters]

Note: IP datagrams may span multiple packets. Values larger than the default
for the underlying network will result in the transport using the network
default MTU. Values smaller than 68 will result in the tranport using an MTU
of 68.

Optimize Internet Connection Speed (Windows 95/98/Me)

By optimizing the MaxMTU & MaxMSS settings along with the RWIN and TTL settings
you can increase dialup modem and broadband connection reliability and
performance by as much as 200%.

What is the MTU and MSS?

MTU stands for Maximum Transmission Unit and in basic terms, it defines the
maximum size of a packet that can be transferred in one frame over a network.

MSS or Maximum Segment Size defines how much actual data can put in that
packet, and it is therefore a marginally smaller value than MTU to allow for
packet addressing and other information.

Why do the default values need to be changed?

By default Windows hard codes the value of MTU to equal 1500 bytes. This value
is adequate for normal LAN networking, but when your connecting to the
Internet with a modem this value is too high. This can show itself in
different ways, the most noticeable affect is less than peak performance.

By adjusting this value to more closely match the requirements of a modem
Internet connection huge performance gains can be achieved.

Below are the instructions on how to modify these values for yourself.
Please remember though, modifying the Windows registry is not for the faint
hearted. Always remember to back it up first!

To change the settings you first have to find the details of your Dial-Up
Adapter. Open your registry and find the key
[HKEY_LOCAL_MACHINE\Enum\Root\Net] and within there will be one or more
sub-keys such as 0000, 0001 ... 000x

Open each sub-key and find the one that contains the value of 'DeviceDesc'
equal to 'Dial-Up Adapter'.

Within that key there will also be another sub-key named 'Bindings'. Open the
'Bindings' sub-key and you will find a string name like 'MSTCP\0000'. Take note
of the four digit number after 'MSTCP' (in this case 0000) and use it in the
next step.

Now go to the key [HKEY_LOCAL_MACHINE\Enum\Network\MSTCP] and expand the sub-
key with the same four digit number as from the previous step.

In this key you will find a value called 'Driver' and it will be equal to
something similar to 'NetTrans\0002'. Take note of this four digit number (in
this case 0002) and use it in the next step.

Now open the key [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\
NetTrans] below there will be one or more sub-key's. Expand the key with the
name equal to the four digit number from the previous step.

Within this key create two new string value named 'MaxMTU' and 'MaxMSS' and
set them to the values from the list below. Note: MaxMSS is usually equal to
MaxMTU - 40 (the standard IP header size).

Dialup Modem
MaxMTU = "576", MaxMSS = "536"
Broadband Cable or DSL
MaxMTU = "1500", MaxMSS = "1460"
Broadband (with PPPOE)
MaxMTU = "1492", MaxMSS = "1452"

System Key: [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\NetTrans]
Value Name: MaxMTU, MaxMSS
Data Type: REG_SZ (String Value)
