I wanted to demo Windows 7 Ultimate, and now I cannot return to Windows 7 Home Premium?

You will have to reinstall windows 7 home premium and all

the drivers required by your hardware to function correctly.

Windows 7 Ultimate contains many networking components

that are not needed in a home computer,

it is a complete waste of resources for something completely unnecessary.

A list of Legal and official Windows 7 .iso download links

can be found here > http://www.heidoc.net/joomla/technology-science/mi...

a few more (same)

can be found here > http://www.mydigitallife.info/official-windows-7-s...

To make or create a bootable Windows 7 USB flash drive or DVD to install Windows 7

use the Windows 7 USB/DVD Download Tool (WUDT),

which is also known simply as ISO Tool

which you can get from here > http://download.cnet.com/Windows-7-USB-DVD-Downloa...

or here > http://images2.store.microsoft.com/prod/clustera/f... (direct download from microsoft)

the drivers you will have to download from the computer manufacturers website.

save them either to a DVD or to a usb device,

ready for installation after you have installed windows 7 home premium.

Note: the copy of windows 7 you will download will be a retail version

not oem,

it will probably have to be activated by telephone.

Windows 7 Home Premium SP1-U is what you need to get.

.

Wherever you chose to get W 7 Ultimate from, that was your HUGE mistake. When you installed it, it replaced your LEGAL W 7 Home Premium with the PIRATED W 7 Ultimate. And W 7 Ultimate likely destroyed the hidden Factory- supplied Recovery partition with your factory-supplied copy of W 7.

"I do not have Genuine Windows." means that W 7 Ultimate was a pirated copy, but you likely knew that. And, you obviously didn't read your PC's User Manual when you first bought it, or you would have BURNED your very own EMERGENCY W 7 Home Premium RECOVERY DVDs, as recommended.

So, call your PC manufacturer, and order replacement Factory Recovery DVDs, they are not free.
