Try this . Start > Run , copy & paste > msconfig & press Enter . Click on the tab marked "Startup" Uncheck all the items except System Tray and Explorer .

Microsoft put out a patch for this but it didn't work for me. Here's what you do: Click on Start, Control Panel, Administrative Tools then Services. Go to the 'Services' tab, find the 'Background Intelligent Transfer' service. Disable it, apply the changes & reboot. Or if you don't want to disable it . Background Intelligent Transfer Service. Uses idle network bandwidth to transfer data. For the majority of Users this feature should be of little use & as such I’d recommend setting it to Manual. Those on highly active Networks may benefit from having this set to Automatic, although it may be worth testing out to see if it does. ================================ Right-click 'My Computer' select 'Manage' , open Services & Applications . Select 'Services' . Set 'Windows Management Instrumentation' to manual (default is Automatic). This service starts up automatically , even if set to manual , but solves slow booting of my PC - might work 4 u !! Also known as WMI .

This places all boot files next to each other on the disk to allow for faster booting. By default this option in enables but on some builds it is not so below is how to turn it on. • Defragment boot files The boot defragment option is usually enabled by default, but it may be disabled, or not properly enabled.

BIOS will shorten or skip some check items during POST to speed up POST after you power on the computer. Enable Quick post in BIOS setup , as long as you have a have a lot of memory . The normal memory test , is tested three times & that alone may take 60 to 90 seconds. ================================== Disable the Windows XP Prefetcher http://www.windows-help.net/WindowsXP/troub-07.html http://www.tweak3d.net/tweak/winstartupnew/ Windows XP has a Prefetcher component, which shortens the amount of time it takes to start Windows and programs. When trouble shooting either Windows or program start-up issues, it might be helpful to disable the prefetcher, because it runs as a background service while other applications are running or loading. To disable the prefetcher: Start the Registry Editor Go to HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ SessionManager \ Memory Management \ PrefetchParameters Double-click the EnablePrefetcher value (remember the value that EnablePrefetcher is set to!) Change the Value data to 0 to disable the prefetcher . Close the registry editor and reboot the computer for the changes to take effect When done troubleshooting, you can re-enable the prefetcher by changing the Value data to its original value. Values for EnablePrefetcher are: 0 - no prefetch 1 - prefetch applications only 2 - prefetch boot only 3 - prefetch both applications & boot (default) I find 5 is best . You can make Windows XP boot faster by 5 - 15 seconds (on some machines). http://www.petri.co.il/make_xp_boot_faster.htm It may also be useful to periodically clean up the prefetch folder, as it may contain obsolete links. The Prefetch folder can be found in the Windows folder on your system drive. Select all the files, and delete them. When done, reboot your computer. ====================================== Application Slow-Downs in Windows XP http://www.scotsnewsletter.com/47.htm Control Panel > Network Connections > Right-click your main network connection , choose Properties > Double-click "Internet Protocol (TCP/IP)" > Click Advanced button > Select WINS tab .

Windows Me/XP uses this feature, which is enabled by default, to restore the files on your computer in case they become damaged. If a virus, worm, or Trojan infects a computer, System Restore may back up the virus, worm, or Trojan on the computer. Windows prevents outside programs, including antivirus programs, from modifying System Restore. Therefore, antivirus programs or tools cannot remove threats in the System Restore folder. As a result, System Restore has the potential of restoring an infected file onto your computer, even after you have cleaned the infected files from all the other locations. Also, a virus scan may detect a threat in the System Restore folder even though you have removed the threat. For instructions on how to turn off System Restore, read your Windows documentation, or one of the following articles: How to disable or enable Windows ME System Restore http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2001012513122239?OpenDocument&src=sec_doc_nam How to turn off or turn on Windows XP System Restore http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2001111912274039?OpenDocument&src=sec_doc_nam
