I've recently been having problems with my registry permissions on my Vista machine. The problems first occurred after updating iTunes to the latest version. Since then, every time I opened iTunes I received a message saying "Please wait while Windows configures iTunes..." 10-15 seconds later iTunes would open normally but I didn't think this was normal. I Googled my problem and found a fix which turned out to be loss of permission to a registry key. I restored permissions and have had no trouble since then with iTunes. Yesterday I installed Office 2007, and the problem has returned. With any of the Office programs that I open, I get the same configuration notice. Again, I scoured the internet and discovered that many of my registry keys have lost full control, and some I can't even assign an owner to. I can't uninstall Office because of a registry error. I get the same error when trying to repair the installation. I am running Vista Ultimate with one user account. Is there a general fix for this problem?
