Mine came with Win7 Pro and I could also have installed Win8 instead. That was some time ago as they had to provide dual paths as Win8.0 had serious issues - Win8.1 has really improved versus the original 8.0 Win7 Pro is VG operating system, Pro is premium. Love the machine after year of use.

The three that I've purchased all came with Windows 7 Professional. They've been working great.

I have bought 2 of these ... the first came with Win 7 Home and the second came with Win 7 Pro. It was very clearly stated in the product description which version it was shipping with.

came with window 7 pro pre-installed, and with a windows 8 disk - I assume there's a downgrade license from window 8 to windows 7 - not sure otherwise

When I purchased this PC in July, 2014, it was Windows 7 Pro. I would check very carefully now because Windows 7 may not be available from manufacturers now. Windows 8 isn't too bad, and with the right start menu software that can be found online for free, it actually works better than I thought. Besides,a free upgrade to Windows 10 will be available very soon.

Has Windows 8 Professional. Not sure if the other answerers are just looking at the spec sheet which is misleading. I own this laptop.

Actually this comes with both! It's the only computer I found like that. Windows 7 is preloaded, and then there is a disc included if you prefer Windows 8. I actually like this model very much. It is very durable and easy to access internal parts with a service door. My only negative comment is that it is a tad slow for my personal liking. But I am biased because I am a multitasker. Most people would enjoy it just fine.

Not a big difference. Win 7 pro has more applications for business needs. Also, Windows 7 pro will recognize more than 16gb system memory Thank you

Hi Jeff, by default the unit runs with Windows 8 pro. Windows 7, however, is also pre installed on the unit. But to be able to use Windows 7, you need to do a downgrade process.Thanks, PCrush

Yes, it has Windows 7 Professional installed; however, the back-up disc, should reinstallation be required, is Windows 8 "upgrade."

Windows 7 Pro comes installed on this computer. The license is attached to the computer.

No, this model comes with Windows 8.1, 64-bit. You can upgrade rather easily using the link in the System control panel. However, it may be less expensive for you to just buy a PC with 8.1 Pro pre-installed. Good luck!
