I would probably need to reinstall Windows as a last resort to fix update-errors. The computer does NOT have a recovery CD or a recovery partition on the HDD. So I would need to download an online ISO and re-install using a DVD.
Can anyone confirm for sure that:
As long as I still have the OEM product key on the bottom of the PC, I can use that to activate Windows Vista once I have re-installed it using a downloaded Windows Vista ISO?
I am getting conflicting info online; some say OEM and downloaded Windows ISOs are different when it comes to the product key. Some say as long as you still have the key it is OK.
Ummm… that PC seems to be custom built and does not even have the Product Key on the bottom. From what I can see on the HDD it seems like it has been upgraded from XP to Vista.
Just to make sure I dont mess things up, I have decided not to reinstall Windows. Instead, I would leave it without the ability to install Windows updates; but I have installed Comodo Firewall and Avast av as another layer of protection (Windows firewall and Windows Defender can not be updated). Also, I asked the clients to use Chrome and Dragon instead of IE.
