Windows Explorer Tip
When launched in Windows Millennium/Win2k/WinXP,Explorer by default will open the "My Documents" folder. Many people prefer the behavior from previous versions of Windows, where Windows Explorer would open and display "My Computer" instead of the new way. To revert to the old way [My Computer by default rather than My Documents as the default], simply edit the shortcut to Windows Explorer, by right clicking on it, and left clicking "Properties" and changing the "Target" box to: "C:\WINDOWS\EXPLORER.EXE /n,/e," [adjust the path/drive letter if needed]. The key is to add the "/n,/e," to the end of the shortcut (don't type the quotes).
Backup your Fresh install
After you complete your clean install and get all your software installed I would recommend that you use something like Drive Image 3 or 4 to do an image of your install partition, then burn the image to CD and keep it. XP is a different creature for some people. If you mess it up when playing around with it, just bring the image back. You can be up and running again in 20 minutes vs. the two to three hours it will take to get the whole thing and all your stuff installed again.
Note the default install of XP is about 1.5gigs and the DI image may be larger that 700 meg. So don't install too much on the OS partition. To help downsize the Image I run the System file checker and reset the cache size to 40 or 50 meg (It's well over 300 by default).
To run it open the command prop and type:
SFC /?
SFC /purgecache
SFC /cachesize=50
and finally rebuild the cache with SFC /scannow (have the CD ready)
I also Delete the Pagefile.sys and hibernate.sys files before running Drive Image..
