Okay! Major surprises with Vista. The Administrator privileges are for the most part gone, and now the System owns many of the Legacy devices and software to stop errant programs. 

 

This is a serious implication for those who install and upgrade Vista over an Older Version of Windows that contains older software and devices. Older versions of Widows use a different version of Installer than Vista. Unfortunately Vista does not make a distinction when upgrading. This means that if you want to uninstall the old software after the upgrade, you cannot is some cases. 

 

Vista has a new Installer permission and you cannot delete the registry keys without the original installer which is to uninstall the remnants left in the Registry using the special permissions. Another surprise is that if you shutoff the Service and then try to hack the registry to delete these Keys you will not be able to do so in some cases. This will leave a lot of junk in your registry, which in my case is logging Warnings and Errors at the rate of hundreds per day, 1520 in the past 5 days. 

 

Therefore, if you are going to install Vista, then do a clean install and avoid all of this headache!!
