Tricks to do in Window XP

.Create your own customized legal notice at Windows Startup

Open Registry by going to START-RUN and typing REGEDIT. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft NT\CurrentVersion\Winlogon. In right hand panel look for two fields by the name legalnoticecaption and legalnoticetext. Modify legalnoticecaption to what you want popup window caption should read and change legalnoticetext to customize whatever message you want.

Speed up menu display

Automatically defrag drives with a new context menu item!

A new Registry import file named context_defrag.inf in Notepad (be sure to save with it with the Save as type set to All Files and not Text Documents) and place the following text inside:

; context_defrag.INF
; Adds Defrag to the right click context menu in Windows XP

[version]
signature="$CHICAGO$"
[DefaultInstall]
AddReg=AddMe

[AddMe]
HKCR,"Drive\Shell\Defrag\command",,,"DEFRAG.EXE %1"

Then, right-click and choose Install. This will add a context menu to XP that allows you to automatically defrag drives, using the command line version of the built-in defragmentation utility. To use it, navigate to a drive in My Computer, right-click, and choose Defrag. A command line window will appear, and that drive will be defragged. When it's complete, the window just disappears.

UPDATE: To remove this functionality, Open regedit.exe and navigate to the following location:
HKEY_CLASSES_ROOT\Drive\shell\
Then delete the Defrag folder and close Regedit.
Then delete the Defrag folder and close Regedit.

Change font size by mouse wheel

Now you can change your font size without going to the font menu.
Just hold 'ctrl' key and scroll your mouse wheel.
Hey... your font size is changing.
This trick will work various softwares like Mozilla Firefox, Internet Explorer...etc.

Save documents in any format

To save a document with an extension other than the one a program wants to use, enclose the entire name in quotation marks. For example, if you run Notepad and save a file under the nameDr.Zit will actually be saved under the name Dr.Z.txt. But if you type"Dr.Z"then the document will be saved under the name Dr.Z. Note that a document so-named cannot be opened via double-clicking since the extension is no longer ".txt".

Correctly set your level 2 cache and improve performance

Open Registry by going to START-RUN and typing REGEDIT. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\SecondLevelDataCache. Based on the kind of CPU you have, this value should change. Here are some of the defaults. Intel Celeron - 128 , AMD Duron - 64. PII and Athalon: 512. Cyrix and AMD K6-3 256. Pentium IV-1024. Figure out what your CPU type is and what L2 cache it supports and set it accordingly. It is important to know what critics have to say about this tweak. Opinions vary and I have put following three articles that have been brought to my attention which may help you understand why it may not be effective in some situations:
Do not change the SecondLevelDataCache entry (from Microsoft technet article)Some third-party sources have erroneously reported that modifying the SecondLevelDataCache registry entry in HKEY_LOCAL_MACHINE \System \CurrentControlSet \Control \Session Manager\Memory Management can enhance system performance. The second level (L2) cache is recognized by the operating system and is fully utilized regardless of the setting of this parameter.
(from Microsoft knowledge base item Q183063)This is not related to the hardware; it is only useful for computers with direct-mapped L2 caches. Pentium II and later processors do not have direct- mapped L2 caches. SecondLevelDataCache can increase performance by approximately 2 percent in certain cases for older computers with ample memory (more than 64 MB) by scattering physical pages better in the address space so there are not so many L2 cache collisions. Setting SecondLevelDataCache to 256 KB rather than 2 MB (when the computer has a 2 MB L2 cache) would probably have about a 0.4 percent performance penalty.
(From an arstechnica article) One of the most infamous NT tweaks since the introduction of NT4 has got to be the "L2 cache" tweak, a lone registry entry which stipulates the amount of L2 cache (or secondary cache) that the OS will make use of. Well, as with many things in life, the effects of this tweak are not so black and white. If you're using a processor that implements a direct-mapped L2 cache design (like Pentium I's), then this registry adjustment is indeed for you. However, if you own any Intel processor post-PI, or any modern AMD processor (K6-2 and newer), then your processor is using a set-associative L2 cache design, and thus you need not specify your L2 cache size. Let me explain.If you choose not to futz with the registry key in question, the OS will call on the HAL (Hardware Abstraction Layer) for retrieval of the L2 cache size when you boot your computer. If this happens to fail, a default value of 256KB is used for all logon sessions on that boot session. This is where the myth that NT can only use 256KB of L2 cache comes from. But it's false. See, the HAL is able to retrieve the processor (L2) cache from any processor using the set-associative cache design, it's only the relatively few processors out there with direct-mapped L2 caches that the HAL won't chat it up with. Thus, this tweak only applies to a select number of people anymore (like people with Pentium I procs between 166-233MHz, as lower rated procs had only 256KB cache).

Speedup boot up sequence

Open Registry by going to START-RUN and typing REGEDIT. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction. In right hand panel look for Enable. Right click on it and set it 'Y' for enable. This is the way I have it set on my computer

. This will help speedup boot time.

How to avoid autoplay of CD ?

Way I like best.Hey this time no registry trick even though there are ways in registry to do it. In earlier operating systems only those CD that had autorun.inf file in their root directory were able to execute on its own but with advent of WINDOWS XP it has become possible with just about anything. Well sometimes it is good but there are other times when you want to avoid this part of automation. What would I do. Simply press SHIFT key when you enter a CD in your CD drive. It won't Auto play. For those of you, who do want a registry hack. Here it is: Open Registry and navigate to [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer] and look for key "NoDriveTypeAutoRun" and set its value to 185 (decimal). This would stop autoplay.

Having problems with Outlook Express ? Does it ask for password everytime you connect ?

Even though this is not a problem for me but there is a chance that it could be a problem for you. Sometimes no matter what you do, Outlook Express forgets your password and asks you to enter it again each and every time you connect to your mail server.I have a solution that may work for you. Open Registry by going to START-RUN and entering REGEDIT and Navigate to HKEY_CURRRENT USER\Software\Microsoft and look for "Protected Storage System Provider". There is a good chance that you will see this folder. If you have it. Simply delete it. More than likely, you have solved your problem

Are you using an computer that is accessed by more than one ? Secure your privacy by cleaning pagefile.

I read about this tweak a long time ago and even found out couple of ways of achieving the same results but wasn't sure of the importance. But you know what, there is reason for everything. Assume your are working on computer where you don't really own the computer or is shared with someone else. Do you want maintain privacy and avoid other know what you were doing etc. Then this tweak may be of interest to you. Go to Control panel Administrative tools, local security policy. Then goto local policies ---> security options.Then change the option for "Shutdown: Clear Virtual Memory Pagefile"

Gain temp access to Administrative privileges even if you are not logged in as administrator

I must be telling you one thing. In most of the cases where Windows XP is installed on a personal computer, users generally have access to administrative account. But you know, it is not in your best interest to log on as administrator for all your computing needs. I must advise you to create a normal user account as well. But what if you are logged in as normal user and happen to download/install some software application that would need administrative privileges Here is the solution. Simply right click on the executable and select run as. You would see a window poping up. Here you can provide one of the userid/password that would have admin privileges That's all you need to run that program with administrative privileges

Have a IDE drive ? Improve disk performance by changing to DMA access mode

If You are an average user, there is a good chance that your are using a IDE hard disk that supports DMA access. Even Windows XP fails to set the DMA mode correctly for the IDE device designated as the slaves on the primary IDE and secondary IDE channels. Most CD-ROMS are capable of supporting DMA mode, but the default in XP is still PIO. Setting it to DMA won't make your CD-ROM faster, but it will consume less CPU cycles. Follow instructions below:1. Open the Device Manager and navigate to "IDE ATA/ATAPI Controllers", expand it and double-click on "Primary IDE Channel"2. Under the "Advanced Settings" tab, verify the "Device 1" setting. If transfer mode is set to PIO Then set it to "DMA if available". Repeat the step for the "Secondary IDE Channel" if You have devices attached to it. Reboot the sytem.

.Improve computer performance by reducing EFS cache validation

Navigate to HKLM\System\CurrentControlSet\Services\NTFS\EFS\Parameters and set the parameter of EFSKCACHEPERIOD to a value between 2 and 30. default is 5. Value suggest the time in seconds the kernel will cache the session key for a user for a given file. The Kernel will not validate the user credentials during this cache period. This has the net effect of faster access to encrypted files that may be opened several times during a given time period.This is helpful in kernel and user mode of the EFS (encrypting file system) as it provides quicker access to frequently use components. Similarly navigate to HKLM\Software\Microsoft\Windows NT\CurrentVersion\EFS and set the value of KeyCacheValidationPeriod to a value in units of second from 1 minute to 1 day (60 to 86400).
Microsoft has an interesting article on this at Registry Keys Used to Tune EFS Caching (Q278256). Read it for complete details.
