I have an HP clone desktop running xp pro. This is a SATA drive type. The issue is that none of the programs that were written to the HDD and none of the programs I install are in the ADD/REMOVE list. The OS uses WMP 10. I prefer WMP 9. Since it is not on the list I cannot remove or rollback. When I try to install 9 the program quits. Apparently the OS cannot handle 9 and 10 at the same time. It CAN handle 6.4 and 9 though. Any ideas? On a different note I ordered a ZORIN CD because it is open source. Any ideas as to how I can make it look and act like XP/ I prefer to download programs from the built in browser as well as download other browsers instead of using the download manager which are more trouble then they are worth. Are there similar backgrounds?
