OEM install win7HP64 AU to Ultimate. Need to do fresh install.

[Bubba2112]

Our Acer came with & home pro 64. we did a AU to ultimate64. The laptop is slowing way down and needs a fresh install. Not sure how to do this. Do i use my original BU disks then use my same AU code and redownload or will i need to call microsoft? the Acer also has a 0 partition. so i'm just lost any help would be great.

Thanks!

I would use the original BU disks. If you have a problem just call MS, it is a very fast and quite simple thing to call them.

ok, but then how do i get ultimate back on the laptop. wife uses the functions of ultimate, so we need that back on and i'd rather not pay for it again.

Take a look at this:
Windows Download and Shop - Microsoft Windows

No install files needed.
Only the Upgrade key is need.
Anytime upgrade only adds-on the Programs & Features from version to version.

The Backup Disks reinstall the factory image which is a corrupt install to begin with, larded with bloatware that smothers Win7 native performance.

I would instead take the opportunity to Clean Reinstall - Factory OEM Windows 7.

After install use Anytime Upgrade to Professional if you need the expensive extra features, which most consumers don't. Compare Windows 7 Editions - Windows 7 Forums

Then after its all set up and running best, save a Win7 or other backup image externally so you don't have to go through it again. Backup Complete Computer - Create an Image Backup
