Today I installed Windows 7 RC1 with a clean install. I next installed MS Office 2007 and Outlook 2007.
Then I downloaded the Avast 2009 Anti-virus Professional and at completion of the install I got the dreaded blue screen of death. After rebooting, I uninstalled Avast and everything is running okay. I just wanted you to know there is an issue with the new windows 7 RC1 software.
