I have Windows 7 Professional installed on my Laptop. I know it is not a good practice to use a non genuine version. However, my query is about the "Get a free upgrade to Windows 10" pop up I have received on my laptop. Can I upgrade to Windows 10 via this pop up? Will it affect the performance of my PC in anyway?
More importantly, is the free upgrade available as of now (because I guess the upgrade was available long back)?
