Make Windows XP Services Effiecient

Windows XP is providing a lot of services....u can find them using the following steps...

Run->type msconfig



You may able to see all the services provided by Windows XP

Here you can view turn on/off ur services...but this is not the right procedure to do so...

Instead try the following step

Run->type services.msc


As you can see, for each services there is a lot of information (this information is not always clear, but gives you an idea whether you probably need it or not...). Here you can change the services start-up type to automatic, manual or disabled. Some services depend on other services to work properly (that's the reason not to turn off services in MSConfig) and others are normally disabled. Right click on a service and pick Properties to make changes to the startup type (first check the tab Dependencies!). Switching a service from automatic to manual makes the service available when needed but disables it on startup by default. To monitor the effect of a service, stop the running service by right clicking on it and select Stop.
Disabling services to recover system resources
There are many Windows services. Most of them you will need for a good functioning Windows system, but some can be turned off safely. Here are services mentioned, which can be switched (almost) safely to manual or even disabled. Read the information carefully and make sure you understand what the service does and/or does not! Keep in mind that possible problems in the future start here (so you will have to fix them here as well). If you are not sure about a service, then don't make any change to the startup type! Don't change them all at a time, if you are not sure what they are for. Don't turn off services which are depended on by other services!
Alerter: Most times this service is not used. It takes care of administrative alerts over a network for administrative purposes.
Automatic Updates: Downloading and installing Windows updates. If you think you don't need this service, you can disable it. Remember that the Windows update website doesn't work anymore without this service, since the introduction of Windows XP SP2. I advise to keep it unchanged. To work properly, the Automatic Updates service also needs Background Intelligent Transfer Service, Event Log and the Cryptographics Services.
Computer Browser: This services lists all computers in a network and gives this information to other computers in the network, when asked for. This makes browsing on the network faster. There is no need for this service, and especially not if you don't have a network situation. With this function disabled, you are still able to browse your network!
Distributed Link Tracking Client: This service is only applicable when you make use of the NTFS file system. If you don't use this file system, you can switch off this service. This services makes sure that linked files on different volumes (possibly somewhere on the network) stay connected. If a file has been moved to another location, the link will be updated by this service. There is probably no need at all to for this services on your computer, so disable it.
Error Reporting Service: Enables the option to report system errors to Microsoft. There is no need to do this, enough reason to disable this service.
Event Log: This services logs issues in the log files, which can be viewed with the Event Viewer (Control Panel, Administrative Tools, Event Viewer). Although you might think it's not useful, do not disable this service but keep it automatic.
Fast User Switching Compatibility: If you don't need the fast switching between user accounts, disable this function. Fast switching of user accounts makes it possible to leave your application open without saving your data. If not needed, don't use this function, it doesn't always work properly.
Help and Support: Without this service, the Windows Help and Support center will not be available. If you don't need this help, switch this service to manual.
IMAPI CD-Burning COM Service: This function is used to able to burn CD-ROM's with the Windows Explorer (copy-paste files to your CD burner). If you don't have a CD-burner, you can disable this service (or switch to manual). It is possible that this service causes troubles in combination with other burning software.
Indexing Service: With this indexing service, you are able to search faster on your computer. The faster searching comes at a cost: the indexing of the content, which slows down your computer. This services is not needed, I advise to disable it for better overall performance.
IPSEC-services: Manages IP security policy, possibly not needed for your system.
Messenger: The Messenger service makes it possible sending messages over the network (it has nothing to do with Live Messenger). This function works by the following command: NET SEND 127.0.0.1 Hello (Start, Run,..), a new message Window should appear if this service is enabled. This service is also available from the internet, which makes it possible to receive strange messages: reason enough to disable this service.
NetMeeting Remote Desktop Sharing: This service provides the possibility to invite others to access your computer as a remote desktop. There is no need for this service. For security issues, you better disable this option.
Performance Logs and Alerts: The making off performance logs will probably lower your systems performance: reason enough to disable it, especially if you never read the log files.
Portable Media Serial Number Service: Needed to reed the serial number of any portable media player. If this function is disabled, there is a chance not to open (downloaded) protected content. You probably can disable this service without any noticeable consequences.
Print Spooler: Necessary for printing. If you don't want to have the option to print, you can disable it.
Protected Storage: This service provides the possibility to safe passwords (email, websites, dial up,..). Remember that passwords can be easily retrieved with freeware software (see the item Forgotten passwords). Although this issue, I prefer to keep this option on automatic.
QoS RSVP: QoS is probably not needed for your network traffic, so you can disable this service.
Remote Access Auto Connection Manager: If you are getting troubles with your internet connection, leave this service on automatic. If you are using a router: disable this service.
Remote Desktop Help Session Manager: If you don't need remote assistance (the other person controls your computer by your invitation), disable this function.
Remote Registry: Thanks to this service, external users are able to make changes to the registry keys over the network connection. This option is not safe, therefore it is better to disable it.
Routing and Remote Access: If there is no need to dial in by others into your computer, disable this service.
Security Center: Service Pack 2 provided Windows XP with the Security Center. The Security Center monitors the proper functioning of your system security (Windows updates, firewall and virus scan). If something is not working properly, you will be informed continuously. I can't imagine why you can't do it yourself, reason enough to disable it.
Server: For sharing local files and printers with other computers on your network. If there is no need to share, disable this service.
Shell Hardware Detection: Essential for automatic playing of connected devices (memory cards, CD/DVD).
Smart Card: No reason to run this service when you don't use a smart card (e.g. for telebanking purposes).
System Event Notification: Almost never used. Leave the service on automatic if you have a network or a portable PC, else disable it.
System Restore Service: This service makes it possible to restore your system to an earlier date if something did go seriously wrong. This service consumes a lot of your system performances while the System Restore doesn't always function properly (and you can loose data!). Disabling this service is a relief for the system performances!
Task Scheduler: This service enables automatic scheduled tasks (like regularly downloading of virus definitions, but also the prefetching which improves sytem performances!). Many applications need this service. If you prefer to do everything yourself, you can disable this service. I prefer automatic.
Theme's: If you don't need the XP look, disable this function. I prefer automatic.
Windows Audio: needed for playing sounds, up to you.....
Windows Firewall (ICF) / Internet Connection Sharing (ICS): This services provides your computer with a software firewall for your internet connection. You can disable the firewall service if you use a third party firewall (do NOT go online without a firewall!). Besides the firewall function, the service provides you with the possibility to share the internet connection with other computers, which is not needed when your network is provided with a router.
Windows Image Acquisition (WIA): This service is used for transferring images from your camera/web cam or scanner. Leave this service on manual if you have one of those devices, else disable the service.
Windows Installer: Needed for installing MSI setup files. Do not disable this option, else windows updates won't be installed.
Windows Search (if installed): For indexing and quickly extended searching through (personal) files. If this search feature is not used, it is better to disable it. Remove the shortcut to Windows Search in the folder Startup (Start, All programs) and deactivate the toolbar Windows Search Toolbar (right click the taskbar, sub Toolbars) as well.
Windows Time: If you prefer to keep you system clock up to date manually (if needed.....), there is no need for an automatic update: disable it as you wish.
Wireless Zero Configuration-service: Needed for automatic configuration of your wireless network connection. If you don't have any wireless network adapter, disable this service.
WMI Performance Adapter: No need for performance information, only the performances? Disable this service.

Windows XP registry tweaks

Most settings can be done easily within Windows. However, for some setting you need to dive into the registry or use one of the many registry tweak utilities (like the Windows XP powertool TWEAKUI). On this page (and other pages), I have described some interesting registry tweaks which you can do yourself, using the registry editor.
NOTE: Be careful editing the registry. Worst case scenario: Windows won't boot anymore. If you are not sure, leave things unchanged! My advise: create a system image before making major changes!

Speed up browsing AVI files (audio/video)

By default, opening folders containing AVI files (audio/video) can be very slow because Windows is trying to extract non important information. This can be solved, by deleting the following key:
HKCR\CLSID\{87D62D94-71B3-4b9a-9489-5FE6850DC73E}

Automatically expanding folder trees

The folder view on the left in Windows Explorer automatically expands if you click on a folder containing sub-folders. You can disable this function with a registry tweak: change the DWORD-value FriendlyTree to 0 (instead of 1) in the following key:
HKEY_CURRENT_USER\Software\Microsoft\ Windows\CurrentVersion\Explorer\AdvancedAutomatically expanding folders will be disabled, expanding a folder is now done by double clicking the folder.

Windows search optimization

Within Windows XP you are able to search your computer for files (Start, Search), but takes some clicking to get what you want! To optimize the search function, you have to make some registry changes. To make changes, navigate to the following key:
HKEY_CURRENT_USER\Software\ Microsoft\Windows\CurrentVersion\Explorerwhere you will find some important DWORD-values. Change these values to optimize your Windows search:
SearchSystemDirs=1
SearchHidden=1
IncludeSubFolders=1

CaseSensitive=0
SearchSlowFiles
=1 (if you have a tape drive, else: 0)

Remove shared folders My Computer

To remove the shared folders in the My Computer view, delete the value {59031a47-3f72-44a7-89c5-5595fe6b30ee} in the following key (export to a reg-file first, to have a backup):
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ Windows\CurrentVersion\Explorer\My Computer\NameSpace\DelegateFolders

Saving Notepad settings

If you are a heavy user of Notepad, you probably like saving the Notepad settings on exit. To make sure your settings are saved, add/Change the DWORD-value fSavePageSettings=1fSaveWindowsPositions=1 in the following key: and
HKEY_CURRENT_USER\Software\Microsoft\Notepad

Disable the balloon tips

Already irritated by the information balloons, covering the important buttons in the Start Menu? Start the registry editor and navigate to the following key:
HKEY_CURRENT_USER\Software\Microsoft\ Windows\CurrentVersion\Explorer\Advanced
change or add the DWORD-values EnableBalloonTips and ShowInfoTip, both with value 0.

Disable the useless Security Center warnings

If your Windows is not provided with one of the well known virus scan and/or firewall software, the Security Center will come with useless repeating reminders. The reminders can be disabled by changing the values AntiVirusDisableNotify and FirewallDisableNotify1 in the following registry key: to the DWORD-value
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center

Remove the low disk space warning

Probably you have seen the irritating 'low on disk space'-warning before, if your hard disk reaches full capacity. This warning message can be turned off by adding the DWORD-value NoLowDiskSpaceChecks with value 1 in the following key:
HKEY_CURRENT_USER\Software\MicroSoft\ Windows\CurrentVersion\Policies\Explorer

Disabling wrapping icon/shortcut labels

Probably your desktop contains icons (shortcuts) with long names, which aren't shown completely (the are wrapped......). With a registry tweak you can disable the title wrapping, create a String value IconTitleWrap with value 0 in the following registry key:
HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics

Disabling the blocking of pop-ups from secured sites

By default Internet Explorer blocks the pop-ups because they are mostly used for irritating advertising purposes. For secured pages (e.g. the login to a bank account), this behavior is not wished. The URL of a secured page is preceded by HTTPS instead of HTTP. The blocking of pop-ups for these HTTPS-pages can be disabled by changing the DWORD-value Allow HTTPS to 1 in the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\New Windows

Command Console tweak

If you are a frequent user of the Command Console (the MS-DOS screen, Start, Run, command CMD), the following tweak will be valuable. To change folders is difficult, using the Command Console. By changing the DWORD-value CompletionChar to 9 in the following registry key
HKEY_CURRENT_USER\Software\Microsoft\Command Processor
With the command CD followed with the first letters of the folder name, you are able to select the folder with the TAB-key (also works with other commands).

Activated NUM-LOCK

To automatically switch on the NUM-LOCK, change the value InitialKeyboardIndicators to 2 in the following key:
HKEY_CURRENT_USER\Control Panel\Keyboard

Automatically defrag system files

To defrag the system files automatically at every boot (to optimize you system), change the value Enable to Y in the following registry key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Dfrg\BootOptimizeFunction

A faster Windows shutdown

Shutting down Windows can take a long time. You can speed this up (at your own risk) with the following tweaks in the registry key:
HKEY_CURRENT_USER\Control Panel\Desktop
Change the following String values:
AutoEndTasks=1
HungAppTimeout=4000
WaitToKillAppTimeout=4000
WaitToKillServiceTimeout=4000

(the last registry value is also present in HKLM\SYSTEM\CurrentControlSet\Control)

Fix for shutting down your computer automatically

In most cases, automatically shutting down can be fixed by installing the motherboard drivers (if not done already). If your computer still doesn't shut down correctly, try this registry tweak. Change the value PowerdownAfterShutdown to 1 in the following key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon

Fix for shutting down Windows slowly (or not at all)

If shutting down Windows takes a long time (or doesn't shut down at all), change the value PowerOffActive to 1 in the following registry key:
HKEY_CURRENT_USER\Control Panel\Desktop

Finding out the reason of a Windows crash

If you would like to know the reason why there was a sudden crash of Windows, change the DWORD-value ShutdownReasonUI temporarily to 1 in the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\ Microsoft\Windows\CurrentVersion\ReliabilityAfter a reboot you will find the reason why your Windows shuts down suddenly in the log files (Control Panel, Administrative Tools, Logfiles). If you are finished analyzing, change the value ShutdownReasonUI back to 0.

A faster NTFS file system

You probably use the NTFS file system (see the properties of your C: partition). You can improve performance by making some changes in the following registry key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Filesystem
Change the following registry values, as you wish:
DisableNTFSLastAccessUpdate = 1 (last file access is no longer registered).
NtfsDisable8dot3NameCreation = 1 (no more double filenames: long names and the old 8.3 variant (the 8.3 file notation is used for the older Windows versions).
NtfsMftZoneReservation = 2 (if there are many files on a partition, the master file table (MFT) can get fragmented, with this tweak there will be no more fragmenting of the file master file table (default value = 1, range 1-4).

GMail introduces Gmail Delegation – Grant access to Gmail Account

                 What is Email Delegation?
Assume that you have two Gmail accounts accountone@gmail.com and accounttwo@gmail.com. If you are signed in accountone@gmail.com and you want to access the emails of accounttwo@gmail.com then the only way is to sign out and re login to the second account or Open these two Gmail accounts on different browsers (for ex: Chrome and Firefox).

Access Multiple Gmail accounts at a time using Email Delegation

With Email Delegation feature from GMail, one can access both Gmail accounts from either of the Gmail account by adding the secondary Gmail account in the primary Gmail account. Below are the steps on How to achieve it…



  1. Visit gmail.com and login using Gmail account which you want to treat it as Primary account
  2. Now go to Settings by clicking on the link (you can find it on the top right corner)
  3. Now go to Accounts tab
  4. You should see a section “Grant access to your account”
  5. Now click on Add another account and key in the secondary Gmail account email address
  6. You should get a verification email on the secondary Gmail Inbox. You should open that email and click on the link to confirm the verification process
  7. Once done, you should see small down arrow will appear beside the email address on the top right corner.
  8. Click on that will open the other Gmail account in one more browser. You can start access Emails from both the accounts.

Is Yahoo! Chat safe...?

Lets start from the networking perspective. As most of you know, any data in network is passed as a packet. Every packet has a destination IP address, source IP address and the message itself.
In this case yahoo chat messages are also transmitted as packets.
On the net you can find yahoo sniffer which sniffs packets to capture yahoo chat packets.
Now the question is… If you have sniffer running on your PC, sniffer can read only those packets that are coming to your system i.e., only your buddy’s messages. then how come you can get your neighbor’s chat messages?
he answer lies here…. the type of hardware device used to connect multiple PC’s (your, neighbors) by your internet provider.

There are two types of devices that can be used :

  • Hub (Ethernet hub)
  • Switch
Hub is a dumb device and Switch is an intelligent device.
Switch uses a mapping table that contain entries of IP address and Lan card MAC address. As packet arrives, switch decides to which PC the packets need to be directed to by looking into Mapping table. There are few sniffers on the web that can modify the mapping table in the switch device to direct all the packets to a hacker PC who has installed this sniffer.
Sniffers that modifies mapping address in the switch are detectable and can be caught.
Sniffers
that only rely on Hub can’t be caught or detected because, they are just sitting on the hackers PC.
Lets take an example. A, B and C are using X ISP and all are connected to the internet by the hub.
What a hub does is that it gets packets from outside world and sends them to all the connected devices without checking the destination IP address embedded in the packet. A, B and C will receive the packets and the LAN card will check the destination IP address to decide whether to discard the packet or not. Lets say, A is chatting with his friend. A,B and C gets A’s friend message but A’s PC accepts the packet, decodes it and shows up the message. B’s and C’s PC will discard it.

What sniffer does is, it sits at the gate of the PC that is on the LAN Card, captures all packets (in this case yahoo sniffer), if it detects yahoo packet, it will decode and show the message.
If B’s PC has installed yahoo sniffer, B can read A’s message and his friend’s message.

Switch device takes the packet check the destination IP address and sends it to only respective PC.
So, if you wanna know whether your network is connected via hub or switch, just run the sniffer and check it for 1 or 2 hours. If you see only your and your buddy’s message then a switch is used; if you see others messages as well then a hub is used( in which case you are in a danger as your messages are leaked).
