It's not only start-up that you'd like to speed up; you can also make sure

that your system shuts down faster. If shutting down XP takes

what seems to be an inordinate amount of time, here are a couple of steps

you can take to speed up the shutdown process:
Don't have XP clear your paging file at shutdown. For security reasons,

you can have XP clear your paging file (pagefile.sys) of its contents

whenever you shut down. Your paging file is used to store temporary files and data,

but when your system shuts down, information stays in the file.

Some people prefer to have the paging file cleared at shutdown

because sensitive information such as unencrypted passwords sometimes

ends up in the file. However, clearing the paging file can slow shutdown

times significantly, so if extreme security isn't a high priority,

you might not want to clear it. To shut down XP without clearing your paging file,

run the Registry Editor (click Start > Run, then type regedit in the Run box) and go to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
Change the value of ClearPageFileAtShutdown to 0. Close the Registry,

and restart your computer. Whenever you turn off XP from now on,

the paging file won't be cleared, and you should be able to shut down more quickly. Note: Please be careful when editing the Registry; you can do a lot of damage here. Don't change or delete anything unless you know exactly what it is.

Choosing between CDMA and GSM

GSM and CDMA are the two main digital technologies that cell phone carriers in the United States use to transmit calls. Of the major operators, T-Mobile and Cingular use GSM, while Sprint and Verizon Wireless use CDMA. Nextel uses another technology called iDEN, but it will be phased out around 2010 due to Nextel's recent merger with Sprint. Since GSM and CDMA transmit calls using different methods, they are incompatible, so a phone used on one network cannot be used on another. And while there are some complex variations, on a more surface level, each technology offers distinct advantages to consumers.GSM is the dominant cell phone technology globally. GSM is the standard in Europe, but it's also present in North and South America, Africa, Asia, Oceania, and the Caribbean. So GSM is a much better choice for global travelers who want to take their phone when they go abroad. GSM phones also use SIM cards, which make it much easier to switch your phone number and contacts list between two handsets.CDMA is used in fewer regions around the world, but it has a very strong footprint in the United States. In fact, its national coverage area here is larger than GSM when you take into account analog networks. Though they won't be around forever, analog networks provide better coverage in rural areas. Also, CDMA carriers have been quicker about rolling out 3G networks. Though the GSM players will catch up eventually, they lag behind as of now.
