Tweaks for WindowsXP.
I have gotten 40 Pms on this so here...
***Updated to0k away Lagesystemcache tweak****
(please note) the location of some of these settings may vary from motherboard to motherboard.
Under "Advanced BIOS features" You should see "Boot sequence" with a list below it (HDD0,Cd rom,Floppy), To ensure the shortest booting time possible, set the hard disk that contains your operating system as the first choice. Most times this will be "HDD0" Then i set disabled to the rest but you should keep them there.
"AGP aperture size"
Please note that the AGP aperture is merely address space, not actual physical memory in use. Although it is very common to hear people recommending that the AGP aperture size should be half the size of system memory, that is wrong!
The best thing to do is keep it half your Video cards on board memory. I reccomend anywhere from 64 to 128. My card has 128mb so my aperture size is 64.
"WAR" (what aero recommends)
any 128 mb card = 64
any 64mb card = 32
any 32 mb card= 64 only if you have 512mb of ram otherwise 32.
a. Ram Timings; Often over looked. make sure to see what your
ram is timed at and set it according to your rams specifications
like( 2.5 3 3 5). Often left by default it is slower.
Learn more about your timings and how to change them !here
b. Make sure to disable any hardware you DO NOT use. like
firewire, onboard audio...
c. Disable any bios and video shadowing
Never used the registry before? To get to it open up "run" and type "regedit".
Be careful you can ruin your system if you mess anything up
"Contiguous file allocation size"
This setting optimizes the contiguous file allocation size for the file system and can be especially useful for disk intensive applications. Open up your registry and go to:
Create a DWORD value named 'ContigFileAllocSize' and set the value to '200' (in hex) or 512 (decimal)
Sure anyone can defrag their harddrive. But what about the boot files? This will allow you defrag the very files you boot up with, placing them right next to eachother for super fast boot up times
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction Select Enable from the list on the right. Right on it and select Modify. Change the value to Y to enable and N to disable. Reboot your computer.
These Settings will fine tune your systems memory management -at least 512MB of ram recommended for the one below..
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
A) 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.
Unload DLLs from memory when not needed to maintain free memory
Create a new Key (a sub-folder, not an entry) called "AlwaysUnloadDll". Once created double-click on the (Default) entry in the right pane and enter a value of 1.
"NTFS speed up"
Speeds up NTFS and general system performance
DisableNTFSLastAccessUpdate=1 Disables constant updating of dates a file/folder was last accessed.
NTFSDisable8Dot3NameCreation=1 To disable support for old DOS 8-character filenames.
If these entries don't exist, create them as new DWORDs.
Note also that if you disable 8Dot3 Name Creation you will have problems installing Norton Antivirus 2003. To successfully install NAV2003, set it to 0 (enabled) first, reboot your system, install NAV2003, reboot once again and set it back to 1 (disabled).
"QoS Tweak" XP Pro only
The QoSRRP in windowsXp is important. This stands for Quality of Service Resource Reservation Protocol. Basically, programs either use QoS APIs and are passed through QoS when trying to access information through whatever bandwidth is available, or they are passed to another API called TCI. One of the differences between QoS and TCI is that it is possible to reserve bandwidth for QoS applications. This is great if you are using QoS applications, but if you don't use any, it means that a percentage (20% by default) of your bandwidth is sitting unused.
To change this, we have to go to Start -> Run..., then type 'gpedit.msc'. Now, open the branches Computer Configuration -> Administrative Templates -> Network -> QoS Packet Scheduler.
Now, double-click the option in the right-hand window 'Limit reservable bandwidth', and then set it to Enabled, and the Bandwidth Limit to 0%.
The L2, or second-level, cache, is an integral part of your CPU. However, XP is very shoddy at detecting it, so setting it manually is sometimes necessary. It's easy to do, though, you simply have to navigate to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\
in the registry and find the value SecondLevelDataCache. You must then adjust it to the value (in kilobytes) of the L2 Cache of your processor.
make sure to click deciemal on the left hand side
Windows XP still 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. Here's how:
1. Open the Device Manager. One way to do that is to right click on "My Computer", select the Hardware tab, and Select Device Manager.
2. Expand "IDE ATA/ATAPI Controllers" and double-click on "Primary IDE Channel"
3. Under the "Advanced Settings" tab, check the "Device 1" setting. More than likely, your current transfer mode is set to PIO.
4. Set it to "DMA if available".
Having programs run when windows loads slows down your start.
There are two ways do disable programs that may be in your startup (like icq, messanger,)
The easiest is to do the following:
1. start --> run --> msconfig
2. Click on the "startup" tab (furthest right)\
3. Unclick any items you don't want to load when windows starts.
Windows XP keeps a record of all files on the hard disk so when you do a search on the hard drive it is faster. There is a downside to this and because the computer has to index all files, it will slow down normal file commands like open, close, etc. If you do not do a whole lot of searches on your hard drive then I suggest turnning this feature off:
1. right click C: and press properties
2. Uncheck "Allow Indexing Service"
3. Apply changes to C:\ subfolders and files.
"Process idle tasks"
Devotes 100% cpu POWA!
In the Run box, type "Rundll32.exe advapi32.dll,ProcessIdleTasks". This frees up any idle tasks running in the background so that Windows XP can devote its full attention to what you want it to do. For example playing graphic intensive games.
**NOTE It can take up to 15 minutes to do so. You would not want to run this task before playing a game or using your machine as it will actually cause any tasks waiting for the system to become idle to be performed immediately.
"Get rid of extra services"
a. type services.msc in the run box click ok.
b. For instructional purposes we are going to turn off the Portable
Media Serial Number service.
c. Find this service in the list and select it with the mouse.
d. Right click and select Properties.
e.Once the properties windows has loaded locate the Start up
type drop down box and select disable.
f.Then just click ok and the next time the computer starts the service will not be loaded.
****Note Below is a list for a PURE GAMING machine. If you use this for anything other than browsing or gaming goto;
http://www.blkviper.com/WinXP/service411.htm. and disable what you dont like
Disable these for GAMING!

Wireless Zero Configuration (Set to automatic if you have a
WMDM PMSP Service
WMI Performance Adapter
For a boost in windowsXP's boot performance. This is done by disabling your unused devices in Device Manager. For example, if you don't have input devices that are connected to one of your USBs or COM ports, disabling them will give you an extra performance boost in booting.
Go to Control Panel -> System -> Hardware tab -> device manager
::Thanks to craweful for this one::
After all is Done defrag your Harddrive
Any questions Post them here.
