Whenever you install new software, it is possible (but not likely) that its installer will overwrite crucial Windows files. To protect yourself from potential problems you can use the Windows System File Checker utility to verify the proper DLL\’s are active.

1. Make sure your Windows CD is in the CD drive
2. Open Start > Run
3. Enter this command: sfc /scannow

What happens if Windows XP is already pre-installed and the company you purchased the computer provides no installation programs whatsoever? I have an AMD processor and have installed SP 3 since as well as a HP computer. The results were disastrous until the patch came out and I lost a lot of programs that had activation codes!
