First, create a shortcut on your desktop by right-clicking on the desktop, choosing New, and then choosing Shortcut. The Create Shortcut Wizard appears. In the box asking for the location of the shortcut, type shutdown. After you create the shortcut, double-clicking on it will shut down your PC.

But you can do much more with a shutdown shortcut than merely shut down your PC. You can add any combination of several switches to do extra duty, like this:

shutdown -r -t 01 -c "Rebooting your PC"
Double-clicking on that shortcut will reboot your PC after a one-second delay and display the message "Rebooting your PC." The shutdown command includes a variety of switches you can use to customize it. Table 1-3 lists all of them and describes their use.

Use this technique to create two shutdown shortcuts on your desktop—one for turning off, and one for rebooting. Here are the commands :

shutdown -s -t 03 -c "Bye exil0r"
shutdown -r -t 03 -c "We'll meet soon ;)!"

What it does

Shuts down the PC.

Logs off the current user.

-t nn
Indicates the duration of delay, in seconds, before performing the action.

-c "messagetext"
Displays a message in the System Shutdown window. A maximum of 127 characters can be used. The message must be enclosed in quotation marks.

Forces any running applications to shut down.

Reboots the PC.

Defragmenting on hardisk won't do much to improve your Windows XP performance. It is better to buy several part of your computer rather than to buy defragmentation software. Here are some tips to improve pc. This is not step by step but free to start on which is more possible and easy to done.

  • If a PC has less than 512 MB of RAM, add more memory. This is a relatively inexpensive and easy upgrade that can dramatically improve system performance.
  • Ensure that Windows XP is utilizing the NTFS file system. If you're not sure, here's how to check: First, double-click the My Computer icon, right-click on the C: Drive, then select Properties. Next, examine the File System type; if it says FAT32, then back-up any important data. Next, click Start, click Run, type CMD, and then click OK. At the prompt, type CONVERT C: /FS:NTFS and press the Enter key. This process may take a while; it's important that the computer be uninterrupted and virus-free. The file system used by the bootable drive will be either FAT32 or NTFS. I highly recommend NTFS for its superior security, reliability, and efficiency with larger disk drives.
  • Disable file indexing. The indexing service extracts information from documents and other files on the hard drive and creates a "searchable keyword index." As you can imagine, this process can be quite taxing on any system. The idea is that the user can search for a word, phrase, or property inside a document, should they have hundreds or thousands of documents and not know the file name of the document they want. Windows XP's built-in search functionality can still perform these kinds of searches without the Indexing service. It just takes longer. The OS has to open each file at the time of the request to help find what the user is looking for. Most people never need this feature of search. Those who do are typically in a large corporate environment where thousands of documents are located on at least one server. But if you're a typical system builder, most of your clients are small and medium businesses. And if your clients have no need for this search feature, I recommend disabling it. To disable file indexing double-click the My Computer icon. Next, right-click on the C: Drive, then select Properties. Uncheck "Allow Indexing Service to index this disk for fast file searching." Next, apply changes to "C: subfolders and files," and click OK. If a warning or error message appears (such as "Access is denied"), click the Ignore All button.
  • Update the PC's video and motherboard chipset drivers. Also, update and configure the BIOS.
  • Empty the Windows Prefetch folder every three months or so. Windows XP can "prefetch" portions of data and applications that are used frequently. This makes processes appear to load faster when called upon by the user. That's fine. But over time, the prefetch folder may become overloaded with references to files and applications no longer in use. When that happens, Windows XP is wasting time, and slowing system performance, by pre-loading them. Nothing critical is in this folder, and the entire contents are safe to delete.
  • Once a month, run a disk cleanup. Double-click the My Computer icon. Then right-click on the C: drive and select Properties. Click the Disk Cleanup button it's just to the right of the Capacity pie graph and delete all temporary files.
  • In your Device Manager, double-click on the IDE ATA/ATAPI Controllers device, and ensure that DMA is enabled for each drive you have connected to the Primary and Secondary controller. Do this by double-clicking on Primary IDE Channel. Then click the Advanced Settings tab. Ensure the Transfer Mode is set to "DMA if available" for both Device 0 and Device 1. Then repeat this process with the Secondary IDE Channel.
  • Upgrade the cabling. As hard-drive technology improves, the cabling requirements to achieve these performance boosts have become more stringent. Be sure to use 80-wire Ultra-133 cables on all of your IDE devices with the connectors properly assigned to the matching Master/Slave/Motherboard sockets. A single device must be at the end of the cable; connecting a single drive to the middle connector on a ribbon cable will cause signaling problems. With Ultra DMA hard drives, these signaling problems will prevent the drive from performing at its maximum potential. Also, because these cables inherently support "cable select," the location of each drive on the cable is important. For these reasons, the cable is designed so drive positioning is explicitly clear.
  • Remove all spyware from the computer. Use free programs such as AdAware by Lavasoft or SpyBot Search & Destroy. Once these programs are installed, be sure to check for and download any updates before starting your search. Anything either program finds can be safely removed. Any free software that requires spyware to run will no longer function once the spyware portion has been removed; if your customer really wants the program even though it contains spyware, simply reinstall it.
  • Remove any unnecessary programs and/or items from Windows Startup routine using the MSCONFIG utility. Click Start, click Run, type MSCONFIG, and click OK. Click the StartUp tab, then uncheck any items you don't want to start when Windows starts. Unsure what some items are? Visit the WinTasks Process Library. It contains known system processes, applications, as well as spyware references and explanations. Or quickly identify them by searching for the filenames using Google or another Web search engine.
  • Remove any unnecessary or unused programs from the Add/Remove Programs section of the Control Panel.
  • Turn off any and all unnecessary animations, and disable active desktop. In fact, for optimal performance, turn off all animations. Windows XP offers many different settings in this area. Here's how to do it: First click on the System icon in the Control Panel. Next, click on the Advanced tab. Select the Settings button located under Performance. Feel free to play around with the options offered here, as nothing you can change will alter the reliability of the computer only its responsiveness.
  • If your customer is an advanced user who is comfortable editing their registry, try some of the performance registry tweaks offered at Tweak XP.
  • Visit Microsoft's Windows update site regularly, and download all updates labeled Critical. Download any optional updates at your discretion.
  • Update the customer's anti-virus software on a weekly, even daily, basis. Make sure they have only one anti-virus software package installed. Mixing anti-virus software is a sure way to spell disaster for performance and reliability.
  • Make sure the customer has fewer than 500 type fonts installed on their computer. The more fonts they have, the slower the system will become. While Windows XP handles fonts much more efficiently than did the previous versions of Windows, too many fonts -- that is, anything over 500 -- will noticeably tax the system.
  • Do not partition the hard drive. Windows XP's NTFS file system runs more efficiently on one large partition. The data is no safer on a separate partition, and a reformat is never necessary to reinstall an operating system. The same excuses people offer for using partitions apply to using a folder instead. For example, instead of putting all your data on the D: drive, put it in a folder called "D drive." You'll achieve the same organizational benefits that a separate partition offers, but without the degradation in system performance. Also, your free space won't be limited by the size of the partition; instead, it will be limited by the size of the entire hard drive. This means you won't need to resize any partitions, ever. That task can be time-consuming and also can result in lost data.
  • Check the system's RAM to ensure it is operating properly. I recommend using a free program called MemTest86. The download will make a bootable CD or diskette (your choice), which will run 10 extensive tests on the PC's memory automatically after you boot to the disk you created. Allow all tests to run until at least three passes of the 10 tests are completed. If the program encounters any errors, turn off and unplug the computer, remove a stick of memory (assuming you have more than one), and run the test again. Remember, bad memory cannot be repaired, but only replaced.
  • If the PC has a CD or DVD recorder, check the drive manufacturer's Web site for updated firmware. In some cases you'll be able to upgrade the recorder to a faster speed. Best of all, it's free.
  • Disable unnecessary services. Windows XP loads a lot of services that your customer most likely does not need. To determine which services you can disable for your client, visit the Black Viper site for Windows XP configurations.
  • If you're sick of a single Windows Explorer window crashing and then taking the rest of your OS down with it, then follow this tip: open My Computer, click on Tools, then Folder Options. Now click on the View tab. Scroll down to "Launch folder windows in a separate process," and enable this option. You'll have to reboot your machine for this option to take effect.
  • At least once a year, open the computer's cases and blow out all the dust and debris. While you're in there, check that all the fans are turning properly. Also inspect the motherboard capacitors for bulging or leaks.

Sality virus discovered in June 4 2003. This virus has keylogger and backdoor capability. Infecting all *.exe (applications) files and running windows infected program in background such as moviemk.exe and run duplicated windows system files.
This virus also disabled task manager and regedit, make folder options change no effect and make computer run slower off course. This virus spread by network connections that have file sharing enabled or by removable media such as zipdisk, diskette and CD (rarely).

When infected zipdisk plugged in to clean computer it will run automatically controlled by autorun.ini and search and kill any active antiviruse software even if it has an uptodate virus definition database. In norton antivirus it will prompt error in autoprotect (navapsvc.exe) but that is ok just let the error prompt open and don't press any command button because if you do the virus will kill norton autoprotect service and control your computer, begin scan imedietly in infected media. It will usually find one or more hidden undeletable file by antivirus thats mean we have to delete it manually. Go to folder options --> view --> select show hidden files and folder and uncheck hide protected operating system files. Go to the locations where antivirus detect it and delete it.

How to avoid it.
  1. Disable autorun for any removable media by pressing shift key while inserting CDROM or zipdisk to avoid running autorun.ini program.
  2. Change folder options setting to view all hidden files including protected windows system files and show the file extensions to see if a file have double extensions.
  3. Antivirus software with up to date database.
  4. Be very aware before running unknown program.
How to disinfect.
  1. Uninstall any antivirus that already been taken over by sality.
  2. Because task manager and regedit disabled, install process explorer. See the process and kill any suspicious software or any uncritical windows program.
  3. Reinstall your antivirus and update with the latest virus database.
  4. Disable system restore. The virus might hide there.
  5. Complete scan your computer. If access denied or unable to repair or delete because the infected file running, kill using process explorer.
  6. Restart after completing complete scan.
  7. Check your antivirus software. If its still running the virus has been destroyed if not follow the next step.
  8. Take the hardisk out and put in clean computer with update antivirus software and scan there. After scan finished put the hardisk back to its origin CPU.



Windows Task Manager is a task manager application included with Microsoft Windows NT family of operating systems that provides detailed information about computer performance and running applications, processes and CPU usage, commit charge and memory information, network activity and statistics, logged-in users, and system services. The Task Manager can also be used to set process priorities, processor affinity, forcibly terminate processes, and shut down, restart, hibernate or log off from Windows. Windows Task Manager was introduced with Windows NT 4.0, previous versions of Windows NT included the Task List application, which had far fewer features. The task list was capable of listing currently running processes and killing them, or creating a new process.

When task manager disabled its very hard for us to see the running process and or to kill not responding process. Task manager disabled may because of virus or intentionally disabled by the administrator. The second causes was rarely case because task manager wasn't critical temper to windows system rather than regedit (registry editor) that can make change to the system behavior. Several virus such as W32.sality.AE make registry and task manager not working. The virus will take control the registry and disable task manager so the change in registry to enable the task manager will be no use.

When hard to re-enable task manager why don't just another better "Task Manager"? My solution for this case is using process explorer. Process explorer has more functionality to see the process in tree mode and the DLL's handles, it also can search the process and handles, kill any suspicious background program and off course it has functionality to replace our troubled task manager ^_^.
To replace task manager with process explorer go to options in process explorer and click/check replace task manager and process explorer will active whenever Ctrl+Alt+Del combination pressed.
To download process explorer click here.
