When you boot up your computer the the overall boot up time depends a lot on the various services that are started during boot process. Generally we are not even aware of these services. You can reduce the boot time of Windows(Vista/XP) or make Windows XP/Vista boot faster by disabling some of unneeded services. Below are the same. You may find some of these present in XP but not in Vista and vice versa. Thats ok. Do take a look at small description given for every servcie and then decide whether you want to disable it or not.  You can also make a note about the services which you changed so that the same can be reverted back to original setting if required.

Got to ‘Start menu’ –> Run  –> Services.msc and press ‘Enter’. Alternatively you can opt for ‘Right click My computer’ –> ‘Manage’ –> ‘Services and Applications’ –> ‘Services’. This will open the services windows. Below are the action that you can perform for the services.

1) AdobeLM Service: Not all computers have this service, still it is useless, just disable it if you have it.

2) Alerter: Disable this one if you are not on a network because you will not receive alerts.

3) Application Management: Set this to manual.

4) ClipBook: Disable this if you are not on a network, since you don’t need to share anything.

5) Computer Browser: Disable this too if you are not on a network, as you don’t need to browse and monitor connected computers.

6) Cryptographic Services: Set this to manual if you are not sure you need it.

7) Distributed Transaction Service: Set this to manual.

8 ) DNS Client: Set this to manual if you are not on a network.

9) Error Reporting Service: Disable this useless service for reporting errors to Microsoft, because they will hardly even reply to you for any error you get. Also saves lots of bandwidth.

10) Help and Support: Set it to manual or turn it off if you do not use the help feature often. You can turn it on again when you want help.

11) HTTP SSL: Set it to manual.

12) Fast User Switching Compatibility: Disable it if you have only a single user on your computer, or if you do not use fast user switching feature much. That is, if you completely log-off and then allow other users to use your computer, then you do not need this. Note that this service is completely useless for low memory computers.

13) FTP Publishing: Disable this if you do not use FTP.

14) Human Interface Device Access: Turn it off if you do not use hot-keys or remote systems on your computer; if you use them sometimes, it is better turn it to manual.

15) InstallDriver Table Manager: Disable it, it does no harm in doing so.

16) IPSEC Services: Set this to manual.

17) Windows Messenger: Disable this if you are not on a network, it uses too much memory and it is a hog. Also, it does no good and sometimes it is likely to become a security threat.

18) MS Software Shadow Copy Provider: Set this to manual.

19) Net Logon: Disable if you are not on a network.

20) IMAPI CD-Burning COM Service: Set this to manual to save memory and time. Do not turn it off if you have a CD writer or a DVD writer attached to your computer.

21) Indexing Service: Turn it off, it uses lots of CPU. If you are an avid searcher, like a maniac, on your computer, leave it on since it will help you. If you know where your files are and do not use search that often, then disable it for your good.

22) NetMeeting Remote Desktop Sharing: Disable this if you do not use Remote Desktop feature; in my opinion, it is a pretty useless feature.

23) Network Provisioning Service: Disable this, iti s useless if you are not on a network.

24) NT LM Security Support Provider: Disable this, its of no use.

25) NVIDIA Display Driver Service: If you do not use the features of nVidia Desktop, this service must be disabled. It is a big hog of memory.

31) Remote Registry: Serious security threat if turned on, you must disable it.

32) Secondary Logon: Useless feature for most, disable it or turn it manual.
