Not at all. They showed me the whole list of all the components it found that it needs to install and let me check/uncheck each one. They are all Toshiba drivers and software, like the DVD player and disc creator, camera software, audio drivers, video drivers, ethernet drivers, Intel chipset drivers, and registry patches. No 3rd party software.
EDIT: Next step it listed all the components it needs to UNinstall before proceeding. They are essentially most of the components they just downloaded, mostly drivers. It's uninstalling them now.
I can't imagine if I did a clean install having to track down and uninstall and then download and reinstall 16 drivers and components. Definitely more room for error if I'd done it manually.
This is all automated.
Well they made one huge mistake. After the Upgrade Assistant completed uninstalling the components and W7 installation was ready, I got a dialog asking me to insert the disc (which was already in -- I'd never been told to remove it). The disc started spinning but the dialog would not go away. The disc was not recognized in Computer. I tried removing and reinserting the disc -- same thing. I could not get past the "insert disc" dialog and I could not get the installation to run. I tried restarting, same thing. I was stuck in an endless loop.
I decided to go to Toshiba Support to look for an answer but the forum did not recognize my ID & password. So I clicked "forgot password" and it didn't recognize my email. So I started all over again with a new registration. I got the validation email, validated it, and went to log in. Password not recognized. So I clicked forgot password and went to enter my email again to get a new password and it said user ID not recognized. So I went back and started all over again, went to the registration page, and entered my email. Of course, it said "user already registered." So I clicked forgot password again. I got the email with my password and went to log in and, you guessed it, password not recognized. The very same one they had just emailed me.
I gave up on the forum and called them. First I gave him a good piece of my mind. After finally getting to where he understood what I was saying, it turned out that all I needed to do was remove the disc, restart, and then insert the disc. Then it was recognized and the W7 installation began.
I had tried reinserting the disc with the computer on, and I had tried restarting the computer with the disc in. The only thing I hadn't tried was restarting the computer without the disc. Now, why did they not say in the dialog, " remove disc, restart, insert disc." Simple.
At any rate, W7 is installing now and will hopefully transfer all my settings, files, and programs.
Boy, when they said it could take up to 6 hours they were right.
