The key for windows 10
By the way, I have a license key for Windows 7, can exchange, I now still do not use the 7th version, on the eight I'm hung tight. I decided to upgrade to Windows 10, and there is no license key for it, and my version of Windows 8 does not allow me to upgrade to Windows 10 for free. In general, anyone who needs a license for Windows 7 is ready to switch to the 10th version.
I do not think that one of the visitors will simply give you a license key for the 10th version free of charge. Use the search, 2 weeks ago I looked and found myself, the working key, put Win 10, especially I did not like. I put it on a laptop, I did not decide to install it on my work computer. I think another half a year, and you can put it on a working computer while it's still damp.
