I was trying to upgrade from Vista Ultimate to Win7 32 ultimate. During compatibility check it listed out a number of programs (itunes, google toolbar, intel pro-wireless,etc.) I went and removed them from the Control Panel-> Progams and Features and restarted the upgrade. Again the compatibility check failed and this time only google tool bar was showing though it has been uninstalled from the system. To make be completely sure, I went into the registry and checked on all things google and deleted relevant data. Also ran a registry cleaner. But running the upgrade again, I had the same result with google toolbar. Why is it happening ? Thanks for any inputs..
