timppu: Yeah I prefer a clean install, I don't need the extra ASUS or Acer crap, and if I do, I can download and install them separately.
I once tried to download Windows 7 ISO from that MS site, but when I entered my Win7 key (that site required it before letting me download it), it complained the ability to download the ISOs are only for retail keys. Fjuck MS.
Snickersnack: You must have had an install disc/ license key mismatch. M$ got retarded with activation around the time of XP. Win XP/ Vista/ 7 have a number of different types of install media and you need the correct one for your key. IIRC it was Retail, OEM, Royalty OEM, and VLK. I actually fled to the Linux world around 2005 over this mess. Not being able to reinstall your OS without jumping through hoops is intolerable.
Microsoft changed their system again with Windows 8 and I think that's still the one they use today. I haven't explored this system but I think there are now actual license keys in the BIOS of PCs from big OEMs. Hopefully it's not such a PITA.
It was not that the Windows 7 installation or activation failed, but I wasn't allowed to download the Windows 7 installation media from Microsoft site, because my Windows 7 key (that is on the sticker of my laptop) wasn't a retail key, but OEM (I guess). The Microsoft site at least back then required you to enter the key, before even allowing to download the installation media. I don't recall there being any option "go here if you have a retail key, or go here if you have an OEM key". Microsoft just does not allow downloading of Windows 7 installation media if you have an OEM key, period. Might even be that the site said I was supposed to contact the PC vendor (ASUS) to get (=buy?) Windows 7 installation media for my system?
I did not get any Win7 installation media (DVD or anything) with my laptop, Win7 was preloaded on the system, and in order to make installation media, I was supposed to run an ASUS utility on the laptop that makes a bootable USB recovery media. So if I have to "reinstall" Windows 7, I was supposed to use that recovery media. (Also that "recovery media creation tool" had some stupid restriction that you were able to run it only once. So what happens if I misplace that USB stick?)
However, when I obtained the Windows 7 installation media (DVD ISO image) elsewhere, I could install Windows 7 clean and then activate it with my legit OEM key.
With Windows 8.x and 10, Microsoft wisened up and lets anyone download the installation media with the MS Media Creation Tool, and install it. Activation is separate from that. (The only exception is Windows 10 Enterprise which can't be downloaded with the MS Media Creation Tool; I learned this last week when at work I was supposed to create two identical Windows 10 Enterprise virtual workstations for our client; sysprep still gives me nightmares, yikes).
