Hello and welcome Ilia but I think you have been sold a pup because that is the version of 7 without the Service Pack 1 (SP1) - the buil should read 7601 not 7600.

OS Version: 6.1.7600.2.0.0.256.1

I would even go as far as saying the version is a pirated one but I don't know how you got this copy so I am assuming there.
Please go to Control Panel open System and see what is in that screen - see my pic

Your system is quite out of date and this can lead to stability issues, so before you continue, go to Windows update in your control panel and check for and install all Windows updates.

You will need to buy a genuine copy as we provide no help for illegal copies.

As SGT Oddball says mate and you can use this tool Genuine Windows - Windows Help as well to check. If you want to go the whole hog then there is this too Activate Windows on this computer - Windows Help

In either case it will soon show if you have a legit copy. Just out of interest where did you get the copy from??
