Clear Out Forgotten Programs
The first step in tuning up your computer's performance is to remove any unnecessary programs. I install new programs all the time. Sometimes I'm thrilled with the new program and I continue to use it. Other times, it doesn't do what I hoped, and the program sits on my computer consuming resources and hurting performance.Follow these steps to remove unneeded programs:
1. | Click Start, and then click Control Panel. |
2. | Click Add or Remove Programs. |
3. | Scroll through the list and examine each program. Windows XP lists how often you use a program and what day you last started it. As shown in Figure 1, the Age of Mythology Trial is a good candidate for removal from my computer. Though I liked the game, I haven't used it recently and it's consuming a lot of disk space. You shouldn't remove anything labeled as an Update or Hotfix, however, because they improve the security of your computer. Figure 1: The Add or Remove Programs window. |
4. | Click each program you no longer need, click the Remove button, and then follow the prompts to uninstall it. |
Free Up Wasted Space
Removing unused programs is a great way to free up disk space, which will speed up your computer. Another way to find wasted disk space is to use the Disk Cleanup tool by following these steps:1. | Open My Computer, right-click Local Disk, and then click Properties. |
2. | On the General tab, click the Disk Cleanup button. Disk Cleanup will spend a few minutes examining your disk. |
3. | The Disk Cleanup dialog box opens. As you can see in Figure 2, it found almost three gigs of space on my computer that it could free up! Figure 2: The Disk Cleanup tool. |
4. | Select the desired check boxes in the Files to Delete list, and then click OK. Disk Cleanup will spend several minutes clearing space. |
5. | If you have more than one hard disk, repeat this process for each hard disk listed in My Computer. |
Defragment Your Computer
I hate newspaper articles that start on the front page but continue somewhere in the middle of the newspaper. I could get through the article much faster if it was printed on consecutive pages like a magazine article. Files on your computer can either be fragmented like a newspaper, or unfragmented like a magazine. Over time, more and more files become fragmented. When a file is fragmented, it takes longer for the computer to read it because it has to skip to different sections of the hard disk—just like it takes me a few seconds to find a page in the middle of a newspaper. Figure 3 compares how a computer reads unfragmented and fragmented files.Figure 3: Fragmented and unfragmented files compared.
1. | Open My Computer, right-click Local Disk, and then click Properties. |
2. | On the Tools tab, click Defragment Now. The Disk Defragmenter opens. |
3. | Click your first hard disk, and then click Defragment. As shown in Figure 4, Disk Defragmenter will work for at least several minutes, though it may take several hours. Figure 4: The Disk Defragmenter tool. |
4. | If you have more than one hard disk, repeat this process for each hard disk listed starting at Step 3. |
Disconnect Unused Network Connections
If you've ever had a network with more than one computer, you probably found it useful to share files between the computers by mapping a network drive. Network drives allow one computer to read and write files to another computer's hard disk as if it were directly connected. I use network drives all the time, and for me, they were the most significant source of slowness.The problem with network drives is that Windows XP will attempt to connect to the network drives when Windows starts. If the remote computers don't respond immediately, Windows will wait patiently. Additionally, some programs will attempt to connect to the network drives when you browse for files and folders. If you've ever tried to open a file and had to wait several seconds (or minutes!), it's probably because the program was trying to establish a network connection—even if the file you are opening is on your local computer.
I am not as patient as Windows, and I'd rather not wait for unused network connections to respond. To reduce this problem, disconnect any unused drives by following these steps:
1. | Open My Computer. |
2. | On the Tools menu, click Disconnect Network Drive. |
3. | Select the network drives that you no longer need, and then click OK. |
Remove Autostart Programs
The next step in restoring your computer's performance is to identify any unnecessary programs that start automatically. Often, programs configure themselves to run in the background so that they appear to start quickly when needed. Some of these programs show an icon on your taskbar to let you know that they're running, while others are completely hidden. These autostart programs probably won't noticeably slow down your computer as it starts up, but they will steal away trace amounts of memory and processing time as your computer runs.Windows XP comes with the System Configurationtool (Msconfig.exe), an excellent way to manage the startup process. To start it:
1. | Click Start, click Run, type Msconfig, and then press Enter. |
2. | On the Startup tab, you'll see a list of all the programs and processes that are set to run when Windows XP loads. |
3. | Speed up your overall start time by clearing the check box next to any item you think you don't need. |
4. | Click Apply, and then restart your computer for the changes to take effect. |
For example, Figure 5 shows Autoruns revealing a file called nwiz.exe that is set to start automatically. I visited The Startup Applications List, typed in nwiz and discovered that it's used to set my desktop layout preferences. I'd like to keep this functionality, so I won't delete it.

The Startup Applications List may provide instructions for removing the startup program. If available, you should follow those instructions instead of deleting the link by using Autoruns.
