According to Microsoft, Windows XP was designed to boot up within about 30 seconds. Add several additional services and that can become a minute. You can probably slush it but not much. It depends on how much additional functionally you want to be included. If you need multiple services enabled (for example Services for Unix) you might need probably up to two minutes. time also depends of speed of your CPU and speed of hard drive. From 2GHz dual core CPU with 2G of RAM and 7200 RPM harddrive you can expect 30 sec boot in most cases. With solid state drive this time is usually around 15 sec.
Slow start and shutdown can be a symptom of Spyware infection or bloated configuration or both. As spyware those days is big business with multimillion profits the best way fighting it is using disk images as described in detail in Using disk images to fight spyware. Also Windows XP registry with time became a real mess. So periodic (say, once a year or two) complete reinstallation are important in keeping your Pc in top shape as for speed on Bootup and shutdown. As for shutdown, one really nasty effect is a setting to clean the content of paging file. It is not uncommon to have 15 min shutdown time with this setting. See How to Clear the Windows Paging File at Shutdown for the location of registry key involved. In case you use Microsoft networking, non-existant shares can dramatically slow down start-up and shutdown.
Amount of RAM also is important. Generally Windows XP is not running that good on 256M PC and Windows 2000 here has an edge. Windows XP is definitely more resource hungry and on 256K PC it feels slower then Windows 2000. 512K are usually OK and if you have 2G only small amount of this memory is used unless you run some very memory hungry applications. Probably 1G is a good compromise between cost and speed for modern desktops and laptops with XP. You generally do not need 2G for XP and can save money.
As for Spyware problems, they are addressed on the other set of pages. I will only restate that in no way you can rely on disinfection. You need to learn to restore the system from the image as described in Using disk images to fight spyware: Softpanorama strategy of fiighting skyware (don't expect to find references to this strategy on AV vendor sites ;-)
Ghost, Acronis or other tool can be used (Linux based analogs of Norton Ghost are free). Clean image from which to restore Windows ensure that no spyware can get you off the tack for more then one hour. Please remember that Google is a dangerous site that malware authors use to speed their creation by buying Adwords. It is prudent to put in the restricted sites list in IE. Generally browsing of "grey sites" should be done in VM environment as VM image can easily be disposable. Microsoft virtual machine is free. VMware player is also free if there is big selection of prepackaged images Linux images for it.
Here we will concentrate on the problem of bloat, not on the problem of spyware. Bloat is probably the second major cause of slowness of XP after spyware infections. To access the level of bloat on a particular PC you need to create the list of services running after booting (before you open any other program) as well as list of start-up programs. This list should be both printed and saved into a file (see for suitable command line tools to do this) and carefully analyzed. It constitutes the important baseline that can tell you what went wrong.
Analysis of you startup configuration is a very important step. Even if you do not find some rogue services installed, the results of analysis usually get you better understanding of what is used by the computer and several services Microsoft and third party services can usually be disabled. Actually many third party services are just a nuisance and should be disabled. Symantec, Adobe, Apple, and ATI are especially bad in this area. They also put unnecessary program into system tray (can be called recidivist system tray abusers ;-)
If you have such a blueprint and understands that meaning of entries, then you can trim unnecessary start-up programs using msconfig from the Run menu and unnecessary services from Control Panel/Administrative Tools/Services. Still if you install new programs on a regular basis Windows can became "dirty" and startup slow pretty quickly so periodic reinstallation from clean Ghost image is a must
If you have just 256M of RAM and run Windows XP large add-ons like Windows Defender are overkill: they slow down the system considerably. It might be beneficial to eliminated them. You also need more lightweight browser then IE.
Generally with 256M you need cut your services and resident programs to bones in order to cut swapping of pages from disk. Watch the activity of your swap file.
The list of running processes after boot-up are visible in any process viewer. Built-in Windows viewer is actually very primitive and you need to use a better substitute, for example, Process Explorer. But just viewing processes it is not enough. You need to write this snapshot into file and analyze and annotate it line by line (most non-standard free Windows Process Viewers has this capability). Many antispyware programs like Windows Defender also have such tools.
Turn off automatic updates. You can do them manually once a week
(you really need to be diligent with this as current generally or worms
is not a joke). Even notifications are pretty taxing and involve
scanning for automatic updates on startup with 3-5 minutes of almost
100% CPU usage when you PC or laptop became sluggish and almost impossible
to work with. If you do not mind drinking a cup of coffee before
starting work it might be a perfect opportunity.
Windows Protector is a resource hog and is slows down 256M and
512M PCs. Here you need to wait you need to spyware protection and you
need for quick and responsive PC. Windows Protector is a good security
tool from the point of view of catching spyware, the problem is that
it is designed for PCs with at least 512M of RAM and CPUs faster then
Periodically, once a week or once a month defragment your C drive
and other drives that you are using frequently. See
Maintaining Windows 2000 Through Defragmentation for details.
The best strategy that I have found is to start defragmentor each
day when you are going for lunch.
Sometimes very slow startup means that you have remote drives
for which server is currently unavailable mapped permanently for your
desktop. The simplest solution is to delete all such mappings.
is not a bad browser that might fit your needs (Firebox and
Netscape both are resource pigs too: not a big improvement over IE).
It has the initial memory footprint of approximately 16M. But you might
suffer from using non-mainstream browser.
- The quickest way to speed up boot times is to use the free Microsoft utility BootVis.exe. Although it's intended primarily for developers, anyone can use it to analyze their boot times and see where there are slowdowns. More important, the tool will also automatically make system changes to speed up your boot time, so you don't need to go into a lengthy analysis of where your slowdowns are and how to solve them
- Depending on your system and how it's set up, you may see only a moderately faster startup time, or you may speed up boot time dramatically. I've seen reports of improvements ranging from a little over 3 seconds to more than 35 seconds. The improvements I found on my systems were moderate-7 seconds faster on one, and 10 seconds faster on another. Think of all the things you could accomplish with another 10 seconds in the day!
- The BootVis utility traces boot time metrics and then displays the results in a variety of graphs showing total boot time, CPU usage, disk I/O, driver delays, and disk utilization.
- Download it from www.microsoft.com/whdc/hwdev/platform/performance/fastboot/default.mspx and extract it into its own folder.
- Go to the folder and double-click on BootVis.exe.
- To analyze how your system boots, choose Trace → Next Boot. (Choose Trace → Next Boot + Driver Delays if you want to trace delays caused by drivers as well as your normal boot sequences.)
- Tell the program how many times to reboot and run the test (the more times it runs, the more accurate the results, although the longer the test takes to run). Click OK, and your system will reboot.
Hack 6: Boot XP Faster
Is Windows XP booting too slowly? Here's how to speed up your boot-time with a quick Registry tweak.
1. Open the Registry Editor and go to HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > ContentIndex.
2. In the right pane will be a value called "StartupDelay." Double-click on StartupDelay to open it. Change the "Base" from Hexadecimal to Decimal, and enter 40,000 (the default setting is 480,000).
3. Exit the Registry Editor and restart your computer. Your computer should boot up considerably faster--while this worked for me on my Windows XP laptop, values lower than 40,000 didn't produce a noticeable difference.

This only takes a couple of keystrokes. Type the code below and hit OK:
“shutdown” tells the computer what command we want to execute and the “-s” switch tells it what to do, which is to shutdown!
shutdown -s -t 60
Now we have added the “-t” switch and a variable, which in this case is “60″. This number is the number of seconds before the computer is shutdown. A dialog will open and display a count down timer!
Give Us Some Info!
shutdown -s -t 120 -c "You better finish, because I shut you down foo!"
The “-c” switch will allow you to give the user some information for the reason of the shutdown.
Shutdown A Remote Computer
shutdown -s -m \\desktop -t 45
I really like this one! The “-m” switch will allow you to shutdown a remote machine, in this case, a computer named “desktop”. For this to work, you must have administrative access to the computer! To see of you do, hit Windows Key + R then type the computer’s name, i.e.:
If you can connect to it, you will be asked to log into the machine with a user name and password. Once confirmed, a window will open displaying the directories available to you. Now you know you can shut it down remotely.
Let’s say that you need to cancel a shutdown in progress. Go to the computer in question, hit Windows Key + R then type command below:
This will abort the shutdown, assuming there is a counter and it hasn’t reached zero yet!

How do I really disable auto-play in Windows XP - Ask Leo!TweakUI, one of what Microsoft calls "Power Toys for Windows XP". It's more than a toy. It allows you to adjust (or 'tweak') several settings that aren't exposed directly by the Windows tools.
Once you've installed TweakUI you'll find a lot of options in it. For our current problem, in TweakUI expand My Computer, and then AutoPlay. Click on Drives and uncheck the drive letter that you no longer want to AutoPlay. Click on Apply and that's it. No more "what would you like me to do" dialogs.
TweakUI has a number of other settings, I encourage you to install it and browse around in it. It's something I install on every computer I run. (The PowerToys page has a number of nifty tools as well, have a look while you're there).

It would be great to download drivers that sped up your hard-disk access by 10's of percent wouldn't it? Well perhaps you can, Intel has made their Application Accelerator (IAA) available since last September. It reduces storage sub-system bottlenecks apparently. If you have a compatible Intel chipset (810 to 860) and a Pentium Celeron, III , 4 or Xeon chip then get on down to :
Read through everything before you start downloading and installing. You may need to pre-install the Intel Chipset Software Installation Utility if you have XP running on a 830 or 845 chipset. Intel also provide a chipset identification utility if your unsure of what you have - it's linked from the same page.
Intel claim very significant increases in boot times and application speed. On a personal note, on my P4 2GHz, applications do start a lot faster. I suggest you do some benchmarking first (a stopwatch is an easy way to measure boot time). I would be interested in results people have had. This also works for 98SE,ME,NT4 and 2000.
NOTE: IAA works well for most, but not all. Judge for yourself. It's easy enough to uninstall if you don't like it.
Microsoft created the Shared Computer Toolkit to help make shared computers more reliable and less time-consuming to maintain. Unlike personal computers, shared computers are:
- Used by many different people who generally don't know or trust each other
- Used in public places where personal privacy and security are big concerns
- Subjected to greater wear and tear due to their frequent use and public availability
The Shared Computer Toolkit is ideal for computers in schools, public libraries, community technology centers, and Internet cafés. It allows those who manage shared computers in these environments to easily:
Constantly running in the background of XP are services--processes that help the operating system run or that provide support to applications. Many of these services launch automatically at start-up. While you need many of them, some are not required, and they can slow down your system when they run in the background.
You can disable services at start-up by using the system configuration utility, similar to the way that you halt programs from running at start-up, except that you use the Services tab instead of the Startup tab. But the system configuration utility doesn't necessarily list every service that launches on start-up. A bigger problem is that disabling services is more of shot in the dark than disabling programs. When you disable a program, you can get a sense of what the program does. But when you disable a service through the system configuration utility, there's often no way to know what it does.
Here is a list of some common services you might want to stop from running at start-up.
- A better way of disabling services at start-up is via the Services computer-management console. Run it by typing services.msc at the command prompt. The Services computer-management console includes a description of all services so that you can know ahead of time whether a particular service is one you want to turn off. It also lets you pause the service so that you can test your machine and see whether that service is needed.
- After you run the console, click the Extended tab. This view will show you a description of each service in the left pane when you highlight the service. The Startup Type column shows you which services launch on start-up--any with Automatic in that field. Click that column to sort together all the services that automatically launch on start-up. Then highlight each of those services and read the descriptions.
- When you find a service you want to disable, right-click it and choose Properties. In the Properties dialog box that appears, choose Manual from the Startup Type drop-down list. The service won't start automatically from now on, but you can start it manually via the console. If you want the service disabled so that it can't be run, choose Disabled. To test the results, turn off any services that you don't want to run by clicking Stop The Service in the left pane, or by right-clicking the service and choosing Stop.
Service What it does Portable Media Serial Number Retrieves the serial number of a portable music player attached to your PC. Task Scheduler Schedules unattended tasks to be run. If you don't schedule any unattended tasks, turn it off. Uninterruptible Power Supply Manages an Uninterruptible Power Supply (UPS) connected to your PC. Automatic Updates Automatically checks for Windows updates. (You can check manually by going to http://windowsupdate.microsoft.com/.) Telnet (service available on XP Pro only) Allows a remote user to log in to your computer and run programs. (This will not be found on all versions of XP Pro.) Wireless Zero Configuration Service Automatically configures a Wi-Fi (802.11) network card. Disable this only if you're not using a Wi-Fi network card.
Try a clean-boot troubleshooting. Clean-boot troubleshooting is designed to isolate a performance problem. To perform clean-boot troubleshooting, you must take a number of actions, and then restart the computer after each action (to test whether the action resolved the problem). These two articles will help you isolate the problem.

For more troubleshooting on shutdown issues, I recommend you visit MS-MVP James Eshelman's Shutdown troubleshooter page here: SHUTDOWN WORKS, BUT IT'S REAL SLOW.
One of the most common causes of Windows shut down problems is a bug in RoxioТs Easy CD Creator (particularly version 5).
Roxio does have a patch available at http://www.roxio.com/en/support/ecdc/software_updatesv5_2.jhtml Keep in mind though that the patch has been known to disable RoxioТs Take Two backup software that came with Easy CD Creator 5 Platinum. You should also keep in mind that version 5 is an old version that Roxio no longer supports. The current version is Easy Media Creator 7. If you suspect that Easy CD Creator may be causing your problem, then I recommend upgrading to a newer version rather than patching an old version.

The quickest way to speed up boot times is to use the free Microsoft utility BootVis.exe. Although it's intended primarily for developers, anyone can use it to analyze their boot times and see where there are slowdowns. More important, the tool will also automatically make system changes to speed up your boot time, so you don't need to go into a lengthy analysis of where your slowdowns are and how to solve them
Depending on your system and how it's set up, you may see only a moderately faster startup time, or you may speed up boot time dramatically. I've seen reports of improvements ranging from a little over 3 seconds to more than 35 seconds. The improvements I found on my systems were moderate-7 seconds faster on one, and 10 seconds faster on another. Think of all the things you could accomplish with another 10 seconds in the day!The BootVis utility traces boot time metrics and then displays the results in a variety of graphs showing total boot time, CPU usage, disk I/O, driver delays, and disk utilization. Download it from www.microsoft.com/whdc/hwdev/platform/performance/fastboot/default.mspx and extract it into its own folder. Go to the folder and double-click on BootVis.exe. To analyze how your system boots, choose Trace → Next Boot. (Choose Trace → Next Boot + Driver Delays if you want to trace delays caused by drivers as well as your normal boot sequences.) Tell the program how many times to reboot and run the test (the more times it runs, the more accurate the results, although the longer the test takes to run). Click OK, and your system will reboot.

Administering Windows platforms using scripts can be a big productivity booster or a headache. Mitch Tulloch, author of Windows Server Hacks, sits down with Don Jones, a Microsoft MVP and the creator of ScriptingAnswers.com, for a no-holds barred interview about the future of scripting.
Removed from client, but will survive on the server: "On the operating system side of things, Monad is then expected to be included in Windows Server Longhorn, expected in 2007"
Just one day after the first public reports of viruses being written for an upcoming feature of Microsoft Corp.'s Windows operating system (see "First Windows Vista viruses unleashed"), the company said it will not include the feature in the first generally available release of Microsoft Vista, due out in the second half of 2006.
The feature, called the Monad Shell, provides a way for users to access the operating system using text-based commands rather than the traditional Windows graphical user interface. In the past, Microsoft has said that Monad will be part of Longhorn, the code name for both the next client and server versions of Windows.
In an interview Friday, Microsoft director of product management Eric Berg said Monad will not be included in the first commercial version of Windows Vista when it is released.
But the product is expected to be included in Windows over the next "three to five years," he said. "Our intention is to synchronize it with both client and server operating systems."
Security experts had worried that if Monad were included in a widely used client, it might become an attractive target for hackers -- especially if the shell were enabled by default.
Whether it will be enabled by default is unclear. "There are multiple ways that we could introduce this technology to the client stream," Berg said.
The first Microsoft product to use Monad will be the next release of Microsoft's Exchange messaging server, code-named Exchange 12, which is also due in 2006, Berg said.
On the operating system side of things, Monad is then expected to be included in Windows Server Longhorn, expected in 2007, and could be available in a future Windows Vista release, said Rob Helm, director of research at Directions on Microsoft Inc. "Presumably, as time goes on, all of Microsoft's products will have Monad scripting interfaces," he said.
Black Viper (amongst others) runs a Windows tweaks page offers many changes and customizations that users can make to MS Windows in the name of greater performance. BV recommends that many active-by-default Windows services be set to manual activation or disabled altogether, to save on memory useage and CPU cycles.
I have taken three systems with clean installs of Windows XP and reviewed these tweaks. Well, the third isn't really a clean install, it has a bunch of software running which any typical user would run e.g. firewall, antivirus, speedfan, etc. The first two are lower-end systems that should theoretically benefit most from this treatment, neither has the prefix “giga” in either its CPU speed or RAM capacity. The last one is a modern system (at the time of writing, anyway).

UPX (the Ultimate Packer for eXecutables) is a free, portable, extendable, high-performance executable packer for several different executable formats. It achieves an excellent compression ratio and offers very fast decompression. Your executables suffer no memory overhead or other drawbacks because of in-place decompression.
Petite is a Win32 (Windows 95/98/2000/NT/XP) executable (EXE/DLL/etc...) compressor. The compressed executables decompress themselves at run time, and can be used just like the original uncompressed versions. Petite also adds virus detection to the compressed executables - they will check themselves for infection every time they are executed.
Changing Windows XP settings should be done very carefully. Tweaking windows is probably more about getting right set of application and scripts and avoiding overloading the system with too many "greedy" applications then about Registry changes. Run disk defragmenter, disk cleanup and registry cleanup. Do not install unnecessary of "bloated" software. Delete applications that you do not need.

Windows Vista will include a new technology known as Freeze Dry designed to maintain application states and unsaved documents even when patches are automatically applied and PCs are rebooted.
Speaking at the Australian Tech Ed conference on the Gold Coast in Queensland this week, senior product manager Amy Stephan offered a preview of the Freeze Dry technology.
Many IT managers plan to automatically install patches and updates on machines during periods when they are inactive, such as overnight or on weekends. However, as some patches require machines to reboot, users who leave documents open and unsaved run the risk of losing that data if the machine is automatically updated.
Freeze Dry eliminates that problem by automatically saving application state and documents and then restoring them once the system restarts, Stephan said.Read Full Story at ZDNet
Defend shared computers from unauthorized changes to the hard diskUnauthorized changes to a hard disk can make shared computers less reliable. Windows Disk Protection helps to prevent users, viruses, spyware, or other programs from making permanent changes to the hard disk by clearing changes each time the computer restarts.
Because certain changes, such as critical updates and antivirus signatures, need to be permanently saved, Windows Disk Protection allows you to schedule such changes to occur automatically at whatever time you choose.
|•||Helps protect operating system files|
|•||Clears changes when the computer restarts|
|•||Automates critical and antivirus updates|
|•||Lets you choose to save changes to disk|
The toolkit also helps to protect user privacy by refreshing the desktop, user settings, and user data each time a new user logs on. Plus, it consolidates several accessibility features into one user interface, so users can more easily access the features they regularly use. For users who are new to computers, the toolkit also provides a variety of suitable online learning resources.
