I got the key for downloading Win7 and couldn't get it to launch so I looked at some of the files and found setup.exe in one of the files and clicked on it. Without thinking, I clicked on it and ended up downloading it over the top of Vista. Now I have Windows 7 Ultimate as my operating system and fortunately I have the Recover Disks to fall back on. So please follow the directions on how to dowload Win7 safely. So far I have had no problems with it and will have till August to take a good look at Win7. I like the new paint job and hope MS fine tunes the engine before the release. It will be interesting to see if they have paid any attention to our feedback regarding our findings to date and what the cost of Win7 will be.
