I think he refers to the fact that any OEM installation, any installation you yourself don't do from scratch, will always be full of crap.

So like he said: Redeem the OEM Windows license, install whatever you want, maybe actually Windows, from scratch, and you should be happy.

I just bought a Carbon X1, nuked Windows and installed Ubuntu. Not sure if I can redeem the Windows-bit or not, but I'm definitely not plagued by crapware anymore.
