Is it running Windows 8 64-bit or 32-bit?

64-bit. It's a full Windows 8 installation, which is usually 64-bit. The only 32-bit systems you might see these days are netbooks with Win 8 RT. The Inspiron 15z is a full laptop, though, not a netbook. The word 'Ultrabook' might seem to suggest it's a netbook but no, it's a full laptop.

Well, it can definitely run a 64 bit os, and, as for Win8: http://www.biostar.com.tw/app/en/mb/introduction.php?S_ID=618#spec The short answer is yes.

It runs Windows 7 Home Premium 64-bit. Not Windows 7 Pro. I guess it was something wrong by who first listed this product on Amazon marketplace.

It can be either 64 or 32. Go here for complete instructions on how to tell which you have: http://pcsupport.about.com/od/windows-8/a/windows-8-64-bit-32-bit.htm

They say it isn't. But it runs fine if changed in compatibility mode. Quick and efficient fix. (Windows 7 64 bit)

I think it is Windows 8, but my son-in-law fixed it so it looks and acts like Windows 7. The instructions for how to do that can be found online. I just don't know where...he took care of it for me!

Yes. I installed it on 64 bit. If I remember correctly there was something special I had to do like "run as administrator", but yes it worked.

I don't know about Windows 8 but it definitely works with 64-bit Windows 7.

Mine is Win 7 64 - just like it says in the product features and product info sections.

I am running it under Windows 7 Professional 64 bit. It also works under Windows 8.1 Pro 64 bit.

Not sure; I run Win7-64bit on all my machines. Looking at Jeffery's post, I'm thinking "yes" but you may have to run it in Win7 "compatibility" mode.

I had 64 bit Windows 7 installed. Since it's a custom build you can tell them what you want.
