I downloaded all the necessary files and had the iCloud menu and iTunes store added to my Windows 7 PC just as instructed. The synching worked perfectly but the next day, my computer took a very, very long time to startup. Somehow, there was a problem with the Apple files conflicting with the computer. I uninstalled all the programs, but still had the problem. I even did a system restore - to a date prior to adding these files - and still no luck Has anyone else experienced this? And if so, any suggestions about what to do to repair the problem?
