Thanks @kooshad. I'm still a user of Windows 7 Professional on my desktop and laptop as I've resisted Windows 10 right from that time when Microsoft in a very devious way tried to force me to upgrade through its naughty update system.
I'll probably not have a choice to upgrade once I upgrade my hardware one day, but I don't look forward to the change. I'm hoping that by that time I'll be much more proficient with using Linux and be able to create a desktop environment with Linux. Thing is however there seems to be the same greediness for making lots of money like Microsoft did, for developing Linux kernels into desktop applications and charging for it.
