Need help in pre-installed Windows

[Anis94]

Hi,
I'm in a situation where I have to delete my laptop HDD completly and reinstall windows. But this laptop came with preinstalled and prevaricated windows 7 pro.

I'm not sure how I can reactivate new windows after installation.

You need a valid key

this windows is preinstalled by the manufacturer and product is now out of warranty hence manufacturer is not ready to help regarding this.

so now there is no chance to get valid key from manufacturer.

Is the laptop still running at all , if so run speccy to get the key.

OS copy will need to come from manufacturer.

Yes. but the question is and i'm also not sure that this way windows will accept the key and activate it or not.
if newly installed windows which same as old one doesn't accept key then nothing i can do due to reformat of all existing partitions.
