Windows 7: lost original disks vista business and office 2007, need to upgrade

I have lost all original software for Vista and office 2007, and i bought windows 7 home premium to upgrade, i realize now that i need to clean install it when i don't have the originals what to do?

Contact your system manufacturer - most sell replacement recovery media for $25-$30.

If full retail versions, contact Microsoft - How to replace Microsoft software

Hi xena , Welcome to the forums , have a look at this tutorial Clean Install with a Upgrade Windows 7 Version It will be of great help to you

Yes, follow pepplys link.

Its easy to do, done it many times for friends or clients that want to wipe and perform a clean install.

The .isos for Windows 7 can be downloaded from the usual, famous legit site run by Microsoft. You bought a key, so you are valid to install.

As for Office, do you need an Office suite installed? If you only do minor tasks, Office Live is free.

I bought the laptop in 2007, the software (including a separate MS project and MS Access) were in disk format and the keys lost along with the covers, i have no copy of the invoices! the fact is all of the software was lost while relocating and shipping! my vista is so slow that i thought if i move to windows 2007, i will be able to transfer my data to another laptop with a better performance.

For your Office, you are probably out of luck. The least you would need is the product key. But you can always use Open Office. That is freeware.

Regarding the upgrade, you can go ahead with a clean installation. But it must be on the same PC where the Vista was. It is an honor system, and you don't want to stretch it.

If it were possible to exchange the Windows 7 home premium with Windows 7 professional, do i still need to do a clean install, and if not do i need to back up my data before upgrading?

Hi xena , Always back up your data first ,It usually is better to do a clean install

Thank you, one more question, most of my history is on my outlook: 6GB although disected into archives, is there a software that i can download that can easily copy the .pst files on my external HD?
