Windows 7: OEM clean install

OEM clean install

Hello, i have a few questions regarding the clean install:

I was wondering the following:

My brother bought a computer with windows 7 home premium x64 (norwegian version) installed on it, but it did not come with an install CD\DVD. Will i able to run a clean install with the ENGLISH home premium x64 ISO version and then use the old product key which originally was for a norwegian version on this new english version? (for some reason there is no norwegian ISO version available it seems).

Also, the windows update function on the computer stopped working properly some time ago and therefore the computer does not have Service pack 1 installed. Will my original OEM product key for windows7 be valid for a english version install which also install service pack 1?

The computer came with a recovery partition, however my brother didnt make a recovery cd which it seems one has to in order to perform a recovery. The computer does not seem to find any image to recover from the boot menu. Also system restore is not an option because the OS is unable to identify any earlier points to actual restore.

thank you for your time.

Clean Reinstall - Factory OEM Windows 7

The .ISO file contains Service Pack 1, however, the .ISO which you install must match the edition stated on your COA sticker (sticker which contains a product key of letters and numbers). The languages are available via Windows Update.

Windows 7 Official .iso Files (Digital River)

A clean reinstall is much better than recovering from the recovery partition or factory recovery disc, as your system comes pre-installed with OEM bloatware which can reduce your performance and corrupt your system.

Furthermore, if you plan to do a complete reinstall, then I would download the latest Ethernet and Network drivers for your model and then save them to another device externally, so you are able to access the Interent straight after the clean install.

1. You can reinstall directly from the recovery partition. What is the make of the PC - every make has a different procedure.

2. You can also burn a recovery/installation disc from the recovery partition.

3. Yes you can also reinstall with any other Home Premium installation disc. The product key you must use is on the COA sticker that is somewhere on the box. The OEM key is useless in that case.

By edition on the coa sticker you simply mean Home premium right? Not the x17-+++?

Regarding the languages, i tried to do a install repair, but it wouldnt work because the system language of the iso i was using was english, and the original which i had installed was norwegian..hopefully that wont be a problem when installing.

Regarding accessing Internet after clean install, is it enough to take a backup of the "drivers" folder in system32 and then just copy it into the system32 folder after i reinstall windows?

No- if you have special drivers that are not already in win7 installation media - you have to reinstall them.

COA sticker must be on the machine somewhere - perhaps under the battery. It is 5 sets of 5 characters. It will be for the Edition that was factory installed.

So if you had Home Premium from the factory - then you must reinstall Home premium for the product key to work

1. I litteraly dont know what the make of the pc is...is there an easy way to find out? It doesnt say in the msinfo32 file.

3. Oh, i thought that was the OEM key. I'm clueless about this stuff.

Yeah, the key sits right below the home premium and some other numbers (on the coa), i just wondered if there were any other criteria that had to match besides both the iso and coa being home premium (and x64).

thx

That's all you need to match.

And how come you don't know the maker of your PC. There must be a name somewhere on the box - unless it is a home built PC.

There will be another sticker on the PC with the name and model number to use when importing any drivers or other software needed after all Important and Optional Windows Updates are finished.
