Last week's column about downloading the test version of the Microsoft's new Windows 7 operating system prompted some questions.
Jerome Franklin of Green Valley, Ariz., asked: "Will I need to unload Windows Vista from my PC before installing Windows 7?"
A No. Just download Windows 7 at www.microsoft.com/windows/windows-7/download.aspx, burn it on a CD, put the disk into your DVD or CD drive and follow the on-screen directions. But you will need to back up your data to avoid losing them. Put the data on a burnable CD, external disk drive or finger-sized flash drive.
Kale Danberg of Brooklyn Park asked: "If I download the Windows 7 test version to replace Windows Vista on my laptop, will the PC automatically return to Vista when Windows 7 test version expires on June 1, 2010?
A No, installing the test version of Windows 7 will erase Windows Vista. Microsoft says you should be "prepared to reinstall a prior version of Windows or the final released version of Windows 7 before the expiration date."
Linda Freeman of Excelsior asked: "If I did download this test operating system and use it instead of Vista, would I have to reinstall my PC's programs? Also, I'm wondering if I should download Windows 7; I'm not a techie."
A You shouldn't have to reinstall any programs that worked on Windows Vista. If you're not technically inclined, it might be better to wait for the final version of Windows 7 to be released later this year.
People who download the free version are essentially volunteering to help Microsoft fix any remaining flaws in Windows 7.
