After having some problems with the smart card reader in my Tablet PC I have decided to move my development to a virtual environment. That way I can format the host OS as many times as I need to (and it seems the only "supported" way to fix the smart card reader problems is to format the machine). I decided that I wanted to move the settings I have for blocking cookies in Internet Explorer. I have spent some time going through the logs from Adaware and SpyBot and trying to keep the cookies that they say are spyware off of my machine. I found that the settings for each cookie are stored in the registry under [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\P3P\History]. Each site has a separate key with a value that shows whether the cookie is blocked or always allowed. I plan on backing up this part of the registry and making sure that I move it to all of the machines that I normally log into to keep the spyware and ad tracking to a minimum.
