To change drive letters

To change drive letters (useful if you have two drives and have partitioned the boot drive, but the secondary drive shows up as "D")

Go to Start > Control Panel > Administrative Tools > Computer Management, Disk Management, then right-click the partition whose name you want to change (click in the white area just below the word "Volume") and select "change drive letter and paths."
From here you can add, remove or change drive letters and paths to the partition.

How to Convert FAT to NTFS file system

To convert a FAT partition to NTFS, perform the following steps.

Click Start, click Programs, and then click Command Prompt.

In Windows XP, click Start, click Run, type cmd and then click OK.

At the command prompt, type CONVERT [driveletter]: /FS:NTFS.

Convert.exe will attempt to convert the partition to NTFS.

NOTE: Although the chance of corruption or data loss during the conversion from FAT to NTFS is minimal, it is best to perform a full backup of the data on the drive that it is to be converted prior to executing the convert command. It is also recommended to verify the integrity of the backup before proceeding, as well as to run RDISK and update the emergency repair disk (ERD)

Rename a Series of Files

When you download photos from your digital camera, they often have unrecognizable names. You can rename several similar files at once with the following procedure. This also works for renaming other types of files.

1.Open the My Pictures folder. (Click Start, and then click My Pictures.) Or open another folder containing files that you want to rename.
2.Select the files you want to rename. If the files you want are not adjacent in the file list, press and hold CTRL, and then click each item to select it.
3.On the File menu, click Rename.
4.Type the new name, and then press ENTER.

All of the files in the series will be named in sequence using the new name you type. For example, if you type Birthday, the first will be named Birthday and subsequent files in the series will be named Birthday (1), Birthday (2), and so on. To specify the starting number for the series, type the starting number in parentheses after the new file name. The files in the series will be numbered in sequence starting with the number you type. For example, if you type Birthday (10), the other files will be named Birthday (11), Birthday (12), and so on.

Speed up your Windows 2000/XP system and save resources at the same time

You can improve performance of your Windows 2000/XP and reclaim memory by simply disabling the services that is also known as "System Services" you don't need which Windows 2000 or XP automatically provide by default.

What Are System Services in the 1st place
System services are actually small helper programs that provide support for other larger programs in Windows 2000. Many of the services are set up to run automatically each time you start Windows 2000. However, if you're not using the larger programs that these services are designed to support, these services are simply wasting RAM that could be put to better use by your applications. While the word "Disable" is used here to describe the idea that you'll remove these services from memory, what you'll really be doing is changing the startup setting from Automatic to Manual. When you do, the services won't automatically start each time you launch Windows 2000 Professional. However, Windows 2000 will be able to manually start the services if they're needed. That way you won't be unnecessarily wasting RAM, but you won't be crippling your system either. Note: If you're running Windows 2000 Professional on a corporate network, you may not be able to adjust system services. Regardless of whether you can or not, you should check with your system administrator before attempting the make these changes.

Changing the startup type of a service from Automatic to Manual is a relatively simple operation. To begin, open the Control Panel, open the Administrative Tools folder, and then double click the Services tool. When you see the Services window, set the View to Detail if it isn't already. Then click the Startup Type column header to sort the services by Startup Type. When you do, all the Services that start automatically will appear at the top of the list.

As you scan through the list of services on your system whose Startup Type setting is set to Automatic, look for the services in listed in the Table below. These are some of the services are good candidates to be set to a Manual Startup Type.

Examples of services that can be safely changed to Manual :-
DHCP Client -- You're not connecting to a specific DHCP server on your local network

Distributed Link Tracking Client -- You're not connected to a Windows 2000 domain

DNS Client -- You're not connecting to a specific DNS server on your local network

FTP Publishing Service -- You don't need your system to act as an FTP server

IIS Admin Service -- You don't need your system to act as an WWW server

IPSEC Policy Agent -- You're not connected to a Windows 2000 domain

Messenger -- You're not connected to a Windows 2000 domain

Remote Registry Service -- You don't remotely access the Registry of other systems on your local network

RIP Service -- You don't need your system to act as a router

Run As Service -- You don't use any applications that run as an alias

World Wide Web Publishing Service
You don't need your system to act as an WWW server
If you find a match and think that your system doesn't need that particular service, right-click on the service and choose the Properties command from the shortcut menu. When you see the Properties dialog box for that service, click the Startup Type drop down list and select Manual. Then click OK. As you change the Startup Type for any service, take note of the service's name. That way you'll have a record of which services you changed and can change them back if you need to, as I'll explain in a moment.

Using the Windows Task Manager
Trick : To determine the amount of RAM you'll regain by disabling unnecessary system services, use the Windows Task Manager. Here's how: Before you disable any system services, reboot your system and don't launch any applications. If you have applications that automatically load when you start Windows, hold down the [Shift] key to bypass the Startup folder. Then, right click on the task bar and select Task Manager from the shortcut menu. When you see the Windows Task Manager dialog box, select the Performance tab. Now take note of the Available value in the Physical Memory panel. After you disable those system services you deem unnecessary, reboot your system in the same manner and compare the Available value in the Physical Memory panel to the one that you noted earlier.

Final thoughts
Keep in mind that you may not find all the services listed in the Table set to Automatic on your system. In fact, you might not even see some of the services listed present on your system. If that's the case, don't worry about it. Each Windows 2000/XP installation is unique depending on the system and installed software, and different sets of services may be installed and set to start automatically.
On the other hand, you may find services other than those listed in Table set to Automatic that you may think are unnecessary. If so, you can find out what each service does by hovering your mouse pointer over the service's description. When you do, a tool tip window will pop up and display the entire description of the service. You can then better determine if the service is unnecessary. Remember, by changing the Startup Type to Manual, Windows 2000 can still start the service if it's needed. If you decide to experiment with changing the Startup Types of certain services, you can monitor the services over time by launching the Services utility and checking the list of running services. If you consistently find one of the services you set to Manual running, you may decide to change the Startup Type back to Automatic.

Set up and Use Internet Connection Sharing

With Internet Connection Sharing (ICS) in Windows XP, you can connect one computer to the Internet, then share the Internet service with several computers on your home or small office network. The Network Setup Wizard in Windows XP Professional will automatically provide all of the network settings you need to share one Internet connection with all the computers in your network. Each computer can use programs such as Internet Explorer and Outlook Express as if they were directly connected to the Internet.
You should not use this feature in an existing network with Windows 2000 Server domain controllers, DNS servers, gateways, DHCP servers, or systems configured for static IP addresses.

Enabling ICS

The ICS host computer needs two network connections. The local area network connection, automatically created by installing a network adapter, connects to the computers on your home or small office network. The other connection, using a 56k modem, ISDN, DSL, or cable modem, connects the home or small office network to the Internet. You need to ensure that ICS is enabled on the connection that has the Internet connection. By doing this, the shared connection can connect your home or small office network to the Internet, and users outside your network are not at risk of receiving inappropriate addresses from your network.
When you enable ICS, the local area network connection to the home or small office network is given a new static IP address and configuration. Consequently, TCP/IP connections established between any home or small office computer and the ICS host computer at the time of enabling ICS are lost and need to be reestablished. For example, if Internet Explorer is connecting to a Web site when Internet Connection Sharing is enabled, refresh the browser to reestablish the connection. You must configure client machines on your home or small office network so TCP/IP on the local area connection obtains an IP address automatically. Home or small office network users must also configure Internet options for Internet Connection Sharing. To enable Internet Connection Sharing (ICS) Discovery and Control on Windows 98, Windows 98 Second Edition, and Windows Millennium Edition computers, run the Network Setup Wizard from the CD or floppy disk on these computers. For ICS Discovery and Control to work on Windows 98, Windows 98 Second Edition, and Windows Millennium Edition computers, Internet Explorer version 5.0 or later must be installed.

To enable Internet Connection Sharing on a network connection

You must be logged on to your computer with an owner account in order to complete this procedure.
Open Network Connections. (Click Start, click Control Panel, and then double–click Network Connections.)

Click the dial–up, local area network, PPPoE, or VPN connection you want to share, and then, under Network Tasks, click Change settings of this connection.

On the Advanced tab, select the Allow other network users to connect through this computer's Internet connection check box.
If you want this connection to dial automatically when another computer on your home or small office network attempts to access external resources, select the Establish a dial–up connection whenever a computer on my network attempts to access the Internet check box.

If you want other network users to enable or disable the shared Internet connection, select the Allow other network users to control or disable the shared Internet connection check box.

Under Internet Connection Sharing, in Home networking connection, select any adapter that connects the computer sharing its Internet connection to the other computers on your network. The Home networking connection is only present when two or more network adapters are installed on the computer.

To configure Internet options on your client computers for Internet Connection Sharing

Open Internet Explorer. Click Start, point to All Programs, and then click Internet Explorer.)

On the Tools menu, click Internet Options.

On the Connections tab, click Never dial a connection, and then click LAN Settings.

In Automatic configuration, clear the Automatically detect settings and Use automatic configuration script check boxes.

In Proxy Server, clear the Use a proxy server check box.
