Can I upgrade from Vista to Win 7 without installing Vista SP1 first? Whn I ran Win 7 Upgrade Advisor it said I needed to install Vista SP1 first. Problem is that I had to uninstall Vista SP1 after I installed it to begin with when it first came out because it caused a myriad of problems which never existed prior to my installing it. After I removed it wth the help of a $49 call to MS and multiple conversations with Dell support. I have had no issues. I am now worried. I want to upgrade to Win 7 but, given my past problems, am not sure its worth it if I have to have SP1. I am ruling out a clean install of Win 7.- Too much work to reinstall all the programs and customize them as they currently are. I will stay with Vista first. Win 7 Upgrade Advisor indicated no other serious issues with upgrading. A very knowledgeable techie friend told me that my problemwith the Vista SP1 install might have been caused by Norton. Any chance that he was right? I would sacrifice Norton 360 to have Win 7. Thanks in advance for helping me resolve this dilemma.
