I asked this question in the hard drive forum, but its not strictly a HDD or OS question. What I am asking here is is it OK to run the same programs installed on a partition from both Windows 7 and XP? For instance, I have an XP, windows 7, programs partition, a games partition, a downloads partition, all on the same HDD. I installed Steam on windows xp, then installed it on windows 7 into the same folder. Launching Steam on both OS's works fine. Can I do the same for simple programs such as firefox or microsoft office? I would hate to have to create a windows 7 programs folder as well as a windows xp programs folder. Does anyone know if this is OK to do and if it is, how do you set up your partitions accordingly? Am I overkilling it, or having a bunch of partitions is probably a smart and organized idea. HDD is Caviar Black 640GB. Thanks!
