My computer suffered a serious problem today. It recovered, but, it took about 35 minutes, and I used Startup Repair, then it still took two reboots. I'm thinking of doing a complete system restore to factory, due in part to this issue, and some other issues I've been having. What if anything do I need to back up from my iTunes to make sure that I don't lose anything from my iPad? Is it necessary to save anything or do I just need to do a backup again once I get done reinstalling my Windows system? I'm running on a Windows 7 64bit PC with iTunes 10. My iPad is running Stock Apple OS, 3.22. Thanks so much. Thanks!
