Reboot my computer come with vista home premium it now have vista ultimate with is expired how do i get back the home premium without the cd

You *DO* have a "boot-disk".

Put the original Microsoft Vista Home Premium DVD-ROM into your drive, and tell the computer to boot from the CD/DVD drive.

you need to use another cd

If you have the windows vista disk, you can reinstall windows to restore it to the original state.
Just be sure you've backed up any data first.

if u mean by the windows vista cd to start it up like reboot, all any of your buddies that work on computers to ask if they have one, or go to your local computer store, ((best buy)) or something else

go to " MY COMPUTER" and alternate click the drive icon select properties and you can eject or stop from there

OK. Hi, You can actually keep upgrade but you have to buy a license from Microsoft.

When you are asked to register you can option to call 800 phone number & explain that you want a license for a second computer. They can issue a new key to activate your upgrade.

Hope This helped If you need more assistance please comment back. Please rate. Good Luck!

It Happens sometime because Machine does not pass information properly so we need to restart our system to reset all settings again.
and Vista still has many bugs on it so these cases are normal until next version release.

Thank you,

just right click my computer then select properties and click the upgrade
