Win XP tweaks

Following is the extract of useful windows XP teaks i found on the net.

1. bootvis.msi : Analyse the boot up sequence and optimise. My PC boot up speeded up from torturous 7 minuts to a more tolerable 3.5 minutes.

2. Utility at http://www.3dcenter.de/downloads/wcpuid.php) is useful.

These Settings will fine tune your systems memory
You need at least 256MB of ram to do this:
Go to Start > Run then type in REGEDIT -and then to the following key:
HKEY_LOCAL_MACHINE\SYSTEM \CurrentControlSet\Control\Session Manager\Memory Management

1.DisablePagingExecutive -Double click it and in the decimal put a 1 - this allows XP to keep data in memory now instead of paging sections of ram to harddrive yeilds faster performance.

2.LargeSystemCache- Double click it and change the decimal to 1 -this allows XP Kernal to Run in memory and improves system performance a lot.

3.IOPageLockLimit - Create a new dword and name it double click it and set the value in hex - 4000 if you have 128MB of ram or set it to 10000 if you have 256MB set it to 40000 if you have more than 512MB of ram -this tweak will speed up your disckcache.


-Unable to delete from Avi files from HD

XP holds files in it's memory even after you have closed the application using them making it impossible to delete them from your harddrive. To fix this:
Start -> Run -> Regedit
Find the HKEY_CLASSES_ROOT\SystemFileAssociations\.avi\shel lex\PropertyHandl er\ directory and delete the "DEFAULT" key.

-Tweak The Swap File

For Users with 256 MB RAM or more this tweak will boost their Windows- and Game-Performance.
What it does: It tells Windows not to use any Swap File until there is really no more free RAM left.
Open the System Configuration Utility by typing msconfig.exe in the RUNConservativeSwapfileUsage =1" under the 386enh section.
Restart your Windows and enjoy better Game performance
command. There in your System.ini you have to add "

-Disable Services

XP Pro runs a lot of services by default that are pointless if your not on a corporate network, the following services are ones that I safely disable thereby freeing up memory but check what each one does first to make sure your not using it for something:

Go to Run and type services.msc, right click on each service, properties and choose disable.

Application Layer Gateway Service,
Application Management
Automatic Updates
Background Intelligent Transfer
Distributed Link Tracking Client
Distributed Transaction Coordinater
Error Reporting Service
Fast User Switching Compatibility
IMAPI CD-Burning
Indexing Service
IPSEC Services
Net Logon
Net Meeting
Remote Desktop Sharing
Network DDE
Network DDE DSDM
Portable Media Serial Number
Remote Desktop Help Session Manager
Remote Registry
Secondary Logon
SSDP Discovery Service
Telnet Themes
Uninterruptible Power Supply
Universal Plug and Play Device Host
Upload Manager
Wireless Zero Configuration
WMI Performance Adaptor

-Speed Up The File System

NTFS is a great file system, but its feature-set comes at a slight cost in performance. You can negate this a little with the following tips:

* By default NTFS will automatically update timestamps whenever a directory is traversed. This isn't a necessary feature, and it slows down large volumes.
Disable it by going to Run and type regedit:

HKEY_LOCAL_MACHINE\SYSTEM \CurrentControlSet\Control\FileSystem and set 'DisableNTFSLastAccessUpd ate' to 1.

* NTFS uses disparate master file control tables to store filesystem information about your drives. Over time these core MFT files grow and become fragmented, slowing down all accesses to the drive. By setting aside a little space, MFT's can grow without becoming fragmented.

In the same key where you disabled the last access feature creat a new DWORD value called 'NtfsMftZoneReservation' and set it to 2.

-Disable DLL Caching

Windows Explorer caches DLLs (Dynamic-Link Libraries) in memory for a period of time after the application using them has been closed. This can be an inefficient use of memory.

1. Find the key [HKEY_LOCAL_MACHINE\SOFTWA RE\Microsoft\Windows\Curr entVersion\Explorer].

2. Create a new DWORD sub-key named 'AlwaysUnloadDLL' and set the default value to equal '1' to disable Windows caching the DLL in memory.

3. Restart Windows for the change to take effect.

-Tweak The Prefetch

1. Run "Regedit"
2. Goto [HKEY_LOCAL_MACHINE\SYSTEM \CurrentControlSet\Contro l\Session Manager\Memory Management\PrefetchParame ters\EnablePrefetcher]

3. Set the value to either 0-Disable, 1-App launch prefetch, 2-Boot Prefetch, 3-Both ("3" is recommended).

4. Reboot.

It will decrease the boot time but double and increase the performance of your XP.

-Performance Increase Through My Computer

Easy enough tweak to usually find out about it on your own, but still, some of us still don't find it right away. So here it is:

Start > right-click on My Computer and select Properties.
Click on the "Advanced" tab.
See the "Performance" section? Click "Settings".
Disable the following:

Fade or slide menus into view
Fade or slide ToolTips into view
Fade out menu items after clicking
Show Shadows under menus
Slide open combo boxes
Slide taskbar buttons
Use a background image for each folder type
Use common tasks in folders
There, now Windows will still look nice and perform faster.

-Remove Windows Messenger

Go to Start/Run, and type: "rundll32 setupapi,InstallHinfSection BLC.Remove 128 %SystemRoot%INFmsmsgs.inf"

Do Not Highlight Newly Installed Programs

Tired of that annoying little window that pops up to tell you that new software is installed? If it gets in the way when you?re logging off, turn it off completely. To do this:

Click Start, right-click at the top of the Start menu where your name is displayed, and then click Properties.
In the Taskbar and Start Menu Properties dialog box, on the Start Menu tab, click Customize.
Click the Advanced tab, and then clear the Highlight newly installed programs check box.
Click OK, and then click OK again.

-Customize the Start menu

The Start menu gets more real estate in XP than in previous versions, and it's more customizable. To make the Start menu display only the applications you want, rather than the default determined by Microsoft:

Right-click in an empty section of the Start menu's left column.
Select Properties > Start Menu > Customize. Here you'll find a list of your most frequently used programs. (XP keeps track of what you use and what you don't, then updates this list dynamically).
Don't want your boss to know that Pinball, Solitaire, and Quake all make your list?

Go to the General tab, click Clear List, and set the counter to zero.

- Search Companion Error

When doing a file search, if you get the error A File That Is Required to Run Search Companion Cannot Be Found

Log on as an Administrator

Go to HKEY_CLASSES_ROOT / SystemFileAssociations / image / ShellEx / ContextMenuHandlers
Delete the key ShellImagePreview
Download reg file

-Allowing Network Access with Blank Passwords

Although you can log in locally without a password, by default, WindowsXP Pro does not allow network users to access the computer without a password.
Typically you will receive an Unknown error 31 if this is the case.

To change this setting:

Run gpedit.msc
Go to Computer Configuration / Windows Settings / Security Settings / Local Policies / Security Options

-Decreasing Boot Time

Microsoft has made available a program to analyze and decrease the time it takes to boot to WindowsXP
The program is called BootVis

Uncompress the file.
For a starting point, run Trace / Next Boot + Driver Delays
This will reboot your computer and provide a benchmark
After the reboot, BootVis will take a minute or two to show graphs of your system startup.
Note how much time it takes for your system to load (click on the red vertical line)
Then run Trace / Optimize System
Re-Run the Next Boot + Drive Delays
Note how much the time has decreased
Mine went from approximately 39 to 30 seconds.

-Re-Enabling System Restore

If you previously disabled system restore through the Group Policy Editor,
the option to start it again does not show in the System Properties.
You can re-enable it again by:

Run the Group Policy Editor (gpedit.msc)
Go to Computer Configuration / Administrative Templates / System / System Restore
Set Turn off System Restore and Turn off Configuration to Disable
Right click on My Computer
Select Manage
Go to Services and Applications / Services
Scroll down to System Restore Service

If there is an existing account, you can unhide it by giving it a value of 1

-Speed up start menu

Start -> Run -> regedit

HKEY_CURRENT_USER\Control Panel\Desktop and then right click on ""MenuShowDelay" and click on "Modify", the figure you have here is in milliseconds. The standard is 400, I have mine set to 50, 0 is instant.
Take your pick

Set your L2 cache

It was on 0 kb after my windows installation.

1. Go to run -> type Regedit

2. Go to _> hkey_local_machine\system\currentcontrolset\contro l\session manager\memory management.

3. At 'secondleveldatacache' set it to
'200' for a Level2 Cache of 512 Kb
For 1 Mb L2 cache fill in '400' ... and so on

(With this freeware you can see how much L2 cache you have

Some of them are from http://www.tweakxp.com/

You mention various Myths here:

1. The Large System Cache Tweak is a Myth.

2. The IO Page Lock Limit Tweak is a Myth.

3. Disable DLL Caching is a Myth.

4. Absolutely nothing EVER should be done to "tweak" prefetching. The setting of EnablePrefetcher is default to 3, which is optimal and will NOT slow down boot performance. Prefetching ONLY improves performance. Leaving it at 3 will improve both boot and application load times.
