Change Your USB port

You can associate your USB device with a different port but it will still only function on one port.  To change what port your device works on, try this:

1.      Download the free application called USBDeview.  This is a tiny app that runs from a single .exe file so nothing is installed on your computer.

2.      Run USBDeview AS ADMINISTRATOR.

3.      Locate the column titled “Last Plug/Unplug Date.”  You may need to use the scroll bar at the bottom because there are dozens of columns that you can’t see.  Now sort on this column by clicking on the column header so that the most recent times are at the top.

4.      Plug-in your USB device using the port that it currently functions on and see what device jumps to the top of the list.  You may need to hit the refresh button in the tool bar.  It may also be helpful to wait a couple minutes if you have plugged-in several devices recently so that there is more of a time offset.

5.      Once you identify the device, look at the columns to the right and write down the device’s vendor ID and product ID.  You need both. For example, my Logitech sound bar vendor ID is 046d and the device ID is 0a23. 

6.      Open device manager and locate your device.  Uninstall the device driver.  Plug-and-play devices will reinstall the driver automatically in step   or the computer will do an online search and download it.  Don’t let this step scar you.

7.      After uninstalling the device you should see it disappear from the device manager.  Now UNPLUG the device from the computer and reboot.  DO NOT plug your device back in after the reboot completes.

8.      Run USBDeview AS ADMINISTRATOR with your device still disconnected.

9.      Sort by Product ID and “Uninstall” all of the entries that have the same vendor & product ID that you wrote down from step 5.  There may be several.  For example, my Logitech sound bar had 6 entries.  If BOTH the vendor and product ID match, uninstall it.

10.  Now decide what USB port you want the device to function from and plug it into that port.  In some cases (like with my sound bar) you may need to go to the control panel and reassign that device as the “default” audio device.  If your device is a printer then you will need to use control panel to re-assign that printer as your default printer etc...

10 Ways To Improve Performance in Windows XP


1. Defragment Your Hard Disk

Imagine you are in a shopping mall, and the person you are with wants to visit fifteen different shops. However, this person ends up walking you up and down the mall six times. Does that make sense? Of course not - as human beings, we like to do things in order to save time.
When your hard drive becomes fragmented, it is literally wasting time by looking in all kinds of places on the disk for all of the pieces of one file. Defragmenting your drive is a great solution to speed up your computer as it puts all the files together in order.
• Click Start > All Programs > Accessories > System Tools > Disk Defragmenter
• Click the drives you want to defrag and click Analyze

• Click Defragment

2. Defragment

 you Hard Disk on BootTo make windows XP start more quickly, you can defragment your boot files. This will decrease the time it takes for your computer to boot.

Boot defragment should be enabled by default; however, it might not be enabled on your computer. To ensure that boot defragment is enabled:
• Hold the Windows Key and press R.
• Type in Regedit
• Go to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction
• Ensure the Enable string value is set as Y
• Exit the Registry
• Reboot

3. Detect and Repair Disk Errors

Over time, your hard disk develops bad sectors. Bad sectors slow down hard disk performance and sometimes make data writing difficult or even impossible. To detect and repair disk errors, Windows has a built-in tool called the Error Checking utility. It’ll search the hard disk for bad sectors and system errors and repair them for faster performance.
• Follow Start > My Computer
• In My Computer right-click the hard disk you want to scan and click Properties
• In My Computer right-click the hard disk you want to scan and click Properties
• Click the Tools tab
• Click Check Now
• Select the Scan for and attempt recovery of bad sectors check box
• Click Start

4. Use a Flash Memory to Boost Performance.

Windows Vista comes with ReadyBoost; Windows XP does not have a tool like this - that’s why we’ll need eBoostr. eBoostr uses a USB thumb drive to create an extra cache of the most commonly used data.
Solid state memory (what your USB drive uses) has excellent transfer speeds; therefore, it can be used to store and access data that is needed quickly. Unlike RAM, the data is stored on your thumb drive and can be used next time you use your computer — a great time saver.
• Plug in a flash drive
• Windows XP will use eBoostr to utilize the flash memory to improve performance.
• Your drive will be configured and you are good to go. Don’t expect miracles - but stick with it and your computer will begin to perform more efficiently.

5. Optimize Your Pagefile.sys.

The pagefile is used as another cache as well as RAM. The pagefile stores data on commonly used applications. If you have less than 512mb of ram, then your page file will be automatically configured. If you have more than 512mb of ram, please continue.
• Right click on My Computer and select Properties
• Select the Advanced tab
• Under Performance choose the Settings button
• Select the Advanced tab again and under Virtual Memory select Change
• Highlight the drive containing your page file and make the initial Size of the file the same as the Maximum Size of the file.
Windows XP sizes the page file to about 1.5X the amount of actual physical memory by default. While this is good for systems with smaller amounts of memory (under 512MB) it is unlikely that a typical XP desktop system will ever need 1.5 X 512MB or more of virtual memory - so change the ratio to 1:1 page file size to physical memory size.

6. Disable Indexing Services

Indexing Services is a little application that uses a lot of CPU. By indexing and updating lists of all the files on the computer, it helps you to do a search for something faster as it scans the index list. But if you know where your files are, you can disable this system service. It won’t do any harm to you machine, whether you search often or not very often.

• Go to Start
• Click Settings
• Click Control Panel
• Click Control Panel
• Double-click Add/Remove Programs
• Click the Add/Remove Window Components
• Uncheck the Indexing services
• Click Next

7. Speedup Folder Browsing

You may have noticed that every time you open My Computer to browse folders that there is a little delay. Windows XP automatically searches for network files and printers every time you open Windows Explorer. To turn this off, do the following:
• Go to My Computer, click Tools > Folder Options…
• Click the View tab.
• Now find Automatically search for network folders and printers and uncheck the box.
• Press OK
• Problem solved!

8. Disable Performance Counters

Windows XP has a performance monitor utility which monitors several areas of your PC’s performance. These utilities take up system resources so disabling is a good idea.
• Download and install the Extensible Performance Counter List
• Then select each counter in turn in the ‘Extensible performance counters’ window and clear the ‘performance counters enabled’ checkbox at the bottom button below.

9. Optimize Display Settings

If you are happy to remove some of the flashy looks of Windows XP, do the following.
• Right click on the desktop and click Properties…
• Click on the Appearance tab.
• Click Effects
• Uncheck the following:
• Show shadows under menus.
• Show windows contents while dragging.
You may see other options you feel you can disable.

10. Remove Unused Fonts

Fonts, especially TrueType fonts, use quite a bit of system resources. For optimal performance, trim your fonts down to just those that you need to use on a daily basis and fonts that applications may require.
• Open Control Panel
• Open Fonts folder
• Move fonts you don’t need to a temporary directory (e.g. C:\OLDFONTS) just in case you need or want to bring a few of them back. The more fonts you uninstall, the more system resources you will gain.
Your computer will be running faster already!
