CD Writer only good for single session

[sweets]

I recently reinstalled the OS on my Dell Dimension 4550. I used the Resource CD to reinstall my programs.
I used the reinstallation disc for Windows XP Home Edition
I dont know how to change the CD writer from single to multisession use. I record one program and cant use the same CD again to add more programs. Please if anyone knows tell me how this is done. Thank you

CD-R can be written to once.

CD-RW can be (re)written to multiple times.

Perhaps I didnt make myself clear... In the past I was able to record multiple programs on one CD until it was full. However since I reinstalled the Windows XP OS I'm only able to record once on any single CD no matter how small the program leaving a tremendous amount of free space useless. I want to know how to change the CD burner from single session to multi session use.
